tabako-ire A Japanese tobacco pouch which was hung from a kurawa (ashtray) netwuke. A tabako-bon is a tobacco cabinet, which can also be called a tabaki-dansu and it has drawers for tobacco and a container usually metal or china for charcoal. It would also have hooks for hanging a pipe (Kiseru) 19th Century examples can be decorated in lacquer. A pipe holder would be known as kiseru-zutsu.

tabby Either a basic weave where the warp thread is woven alternatively over and under each weft thread. Or, it is a 17th Century name for silk taffeta which has a changeable surface similar to that of shot silk.

tabernacle clock A Renaissance period German clock in the form of a turreted tower, often with a dial on each of the four vertical sides, and with a balustraded gallery top that contains hour and quarter hour bells.

table clock A spring driven clock always set within a flat-based case of metal or wood. The dial would be on the upper or front surface, there could be subsidiary dials on the sides and back. They were first made in France and Germany in the 16th Century.

taffeta A fine tabby weave silk fabric, it was used in Britain from the 14th Century and more commonly used from the 16th - 19th Centuries for cushion covers and curtains. It was pulled and stretched from the 17th Century and a gum type substance was spread over it to make the appearance seem water finished.

Talbert, Bruce - (1838-81) Architect and furniture, metalworkand wallpaper designer. Talbert's furniture is simple and functional - a reaction against the overly elaborate gothic revival. It is bulky but practical and well-proportioned, and decorated with panels of lighter wood, tiles, Gothic tracery or shallow carving. Talbert published an influential pattern book in 1867.

talking doll - In the early 19thC, dolls that could say 'mama' or 'papa' were developed in Germany by Johannes Malzel of Regensburg (the sound was produced by a bellows when the limbs were moved), and in Britain by Anthony Bazzoni of London. Some talking dolls dating from the late 19thC contained phonographic wax cylinders.

Tallboy - High chest comprising one chest on top of another, with seven or more full-width drawers and a top pair of half-width drawers. The top chest is generally slighlty narrower than the lower one. Tallboys, also known as chests-on-chests, were introduced in the early 18thC and derived from the chest-on-stand - a chest of drawers on a stand like a lowboy.

tambour - 1A flexible shutter used for roll-top desk lids and sliding doors for cupboards. Tambour covers are made from narrow slats of wood glued to a canvas or linen backing, and were developed in France in the iSthC. 2 A pair of wooden hoops that form a frame to hold embroidery while it is being worked on. The resulting design, stitched in a continuous line of cross-stitches, is known as tambour work and was used to decorate white muslin dresses and accessories, especially 1780-1850.

tang - Long shank on sword blade to which the hilt is fitted.

tankard - Drinking vessel with handle for beer, ale or cider. The earliest surviving tankards from the 16th and 17th centuries retained the same basic form - straight, tapering sides with S-shaped handle, rectangular thumbpiece and a hinged lid - until lidded tankards went out of use in the 18thC. Open tankards or mugs were used from the 19thC.

tantalus - Decorative stand, case or box for cut-glass decanters, fashionable from the mid- 19thC until the Edwardian period in Britain. It is usually for two or three decanters, but can be for up to six. The decanters can only be removed by raising or lowering the overhead handle or bar which locks them in place.

Tapestry - Handwoven fabric in which a design or picture is worked in during manufacture using the weft (crosswise) threads, although the term is loosely used for any woven wall-hanging or upholstery. Tapestries are usually woven with wool, silk or both, and take the name of the factory that produced them, such as gobelin.

tapestry-weave - See kilim.

targe - Light Scottish circular shield made of wood and leather with central boss, used 16th to 18th centuries.

tastevin - Small, shallow bowl or cup for wine-tasting. The French version has a single ring handle and is often attached to a chain or ribbon worn around the neck. The 17thC British version has two scroll handles.

tÍte-a-tÍte - See cabaret.

tavern clock - Georgian wall timepiece with a weight-driven movement, which was developed c.1720 and made into the early 19thC. The large dial is unglazed and the trunk below it houses the weights and a seconds-beating pendulum. The clocks were also known as Act of Parliament clocks, after a 1797-8 Act which taxed clocks and timepieces. This supposedly resulted in private owners putting away their clocks and relying on public clocks. The Act was soon repealed, following a petition from clock-makers.

Tazza - Italian for 'cup', originally the name of a shallow drinking vessel used in 16th and 17thC Italy. It later came to refer to other shallow or virtually flat dishes raised on a central stem also known as comports.

tea bowl - Small, tapering circular cup without a handle and sometimes with a saucer, for drinking tea. The first European examples were based on the Chinese tea bowl and made in silver from the late 17thC and in ceramics and glass during the 18thC.

tea caddy - Box or casket with a hinged lid and lock used for storing tea leaves. Caddy is derived from the Malay kati, a unit of weight for tea. When tea was first introduced to Britain in the 17thC it was stored in porcelain jars, also known as caddies, which were imported from China. Tea was very expensive in the 18thC and kept in lockable silver or wooden caskets, originally known as tea chests. By the end of the century the name had changed to caddy.

tea ceremony wares - Pottery such as bowls, water jars, tea caddies (natsume), charcoal burners (hibachi), incense boxes (kogo and kobako), utensil box (satsubako) used for the traditional Buddhist tea ceremony. In Japan the ceremony is known as cha no yu (hot water for tea). Much Japanese tea ceremony ware, such as raku ware, is rough, irregularly shaped earthenware, in keeping with the simple origins of the ritual.

tea kettle - Large vessel resembling a teapot made for holding hot water, produced in ceramics, silver and sheffield plate from the early 18thC and electroplate from the mid-19thC. The kettles usually had a matching tripod stand and spirit lamp. The tea kettle was superseded by the tea urn c. 1760, but was revived in the 19thC.

tea table - Small, lightweight, easily moved table. tripod tables were replaced by four-legged examples with a galleried or tray top towards the end of the 18thC, and these were also known as silver tables or china tables. Some versions have a fold-over top -rather like a card table without the refinements for games.

tea urn - Large, pear-shaped, lozenge-shaped or spherical hot-water um with two handles, a domed cover with finial and a spigot and tap. Some examples have a red-hot iron inserted into a central tube in the body of the urn, others are heated by a spirit lamp.

Tea urns were made in silver, electroplate, copper, japanned metal or porcelain, largely replacing the tea kettle from the 1770s to mid-19thC in Britain and Europe.

tea-dust glaze - Greenish-brown glaze popular on Chinese 18thC porcelain. Known as cha ye mo, it was achieved by blowing green glaze powder through a fine gauze onto a brown glaze before firing.

teak - One of the hardest, strongest and most durable furniture timbers of all. True teak is from India and Burma, but other similar woods are wrongly called teak. It is usually golden-brown in colour and darkens with age to medium and deep brown, sometimes with dark markings. It is slightly oily and smells leathery. It is so hard that cabinet-makers often charged a higher price to cover the costs of the extra work involved and the repair of blunted tools. Teak was used sparingly in the 18th and 19th centuries for table tops, chairs, chests, and campaign furniture.

teapot - Covered vessel, generally of silver or ceramics, used for infusing and serving tea, and made in several different styles and sizes. Tea was first imported to Britain in the second half of the 17thC. Teapots are generally shorter and rounder than coffee or chocolate pots, and the spout, which is always opposite the handle, is positioned nearer the bottom of the pot. punchpots closely resemble teapots although they are usually much larger.

Teapoy - 1 Small tripod table which was introduced in the early 19thC. From the 1820s, the table top was replaced by a wooden box which was used to store tea. 2 Large, earthenware or porcelain tea caddy.

tear - See air-beading.

Telescope - Instrument for magnifying distant objects, invented in the early 17thC, and consisting of telescopic wooden or metal

tubes containing lenses.

temmoku glaze - Black or dark brown glaze found on Chinese 10th- 13thC (song dynasty) stoneware. The ware was also made in Japan for use in the tea ceremony. The glaze, when streaky, is known as a hare's fur glaze.

Tempera - Painting medium consisting of powdered colour pigments, egg yolk or egg white and water; used for panel painting until the 15thC when it was superseded by oil paint.

tenon - See joining.

tent stitch - Small diagonal stitch that spans one mesh of canvas or other material, worked in horizontal or diagonal rows.

term - Short for terminal figure, a half statue or bust on a pillar or pedestal.

Terracotta - The name, translated from the Italian as 'baked earth' for a low-fired unglazed earthenware. The clay used is often rich in iron and therefore fires brick-red. A vogue for Classical Greek style c. 1860-80 prompted British factories to produce terracotta wares, including wedgwood, minton, doulton and Torquay Potteries. Terracotta has been used for a wide range of wares - from figures, plaques, candlesticks and vases to garden urns and flowerpots. Terracotta can be made with a slightly glossy surface and is suitable for painted decoration without any need for subsequent glazing and firing. The body is usually left unglazed, but some practical pieces such as jugs are glazed on the inside in order to make them waterproof.

Tester - A wooden canopy over a bedstead, chair or pulpit. The tester is supported on four posts, or on two posts and a back panel or headboard. See bedstead.

Testoon - British silver portrait coin issued by kings Henry VII and Henry VIII, with a face value of 5p (12d), later known as the shilling c. 1550.

Thaumatrope - 1 Optical toy, developed in the late 1820s, consisting of a card or disc with two different figures drawn on each side. When it is rotated the two figures appear to combine into one. 2 Cylinder bearing a series of figures on the inside and a series of slits on the outside. The figures are viewed through the slits and when the cylinder is rotated appear to be moving. The effect is similar to that produced by a zoetrope.

The commode chair, - with a hinged seat enclosing a chamber pot, was introduced in the mid-Georgian period, and known by the Victorians as a night commode.

Thebes stool - Wooden stool with a thonged leather or wooden seat based on an Egyptian design and introduced by liberty in 1884.

Theodolite - Surveying instrument for measuring vertical and horizontal angles, invented in 1571 by a British mathematician,

Thomas Digges, but developed by engineer Jesse Ramsden c.1790. It incorporates a small telescope which moves horizontally and vertically, and often a magnifying lens and spirit level.

Thonet Brothers - Austrian furniture-makers established Vienna, 1842, which specialised in bentwood furniture, perfected by its founder Michael Thonet (1796-1871). Furniture was exported to the USA and Europe, especially after mass-production techniques were introduced in 1859. By 1871 Thonet Brothers was the largest furniture-making firm in the world. The company changed its name to Thonet-Mundus in 1923, producing tubular steel chairs designed by Marcel breuer, Ludwig mies van der rohe and le corbusier among others.

Threading - 1 Threads of molten glass used to decorate glassware, similar to, and often referred to as trailing. Threads or trails of glass are applied onto the glass body when it is still in its molten state, and can then either be left raised on the surface or rolled into the glass body. From 1876 threading was usually carried out by for the production of ceramic figures. In 1763, the factory made a definite move towards the luxury market, and wares imitating meissen, sËvres and Japanese designs were produced. These were often finished by outside decorators such as James giles. A new period began in 1783 under the Flight family and, from 1793, under the Flight and Barr families, with an improved soft-paste formula. Products ranged from simply decorated teawares to elaborate regency vases, and ornaments decorated in rich enamels and gilding by first-class artists such as Thomas Baxter and Samuel Astles. bone china was introduced in 1800 but only achieved pure translucency and whiteness from 1820. Some decoration was done by Robert Chamberlain's rival Worcester factory. The resulting ware, together with Chamberlain's own bone china produced since 1791, became known as 'Chamberlain's Worcester'. The two companies merged in 1840. New management in 1852 changed the factory's name to Kerr & Binns, and from 1862 it became the Royal Worcester Porcelain Company. Victorian Worcester is often richly gilded and painted in enamels - flushed colours against an apricot ground. Specialities included japonaiserie in the 1870s and 80s, figures, including children, modelled by James Hadley (1837-1903), parian ware ornaments and elaborate renaissance-style vases. High-quality painted decoration, often signed by the artist, was frequent at the end of the 19th and early 20th centuries.

thumbpiece - Metal knob or lever, also known as a billet, on the lid hinge of a vessel, allowing it to be opened with the thumb while holding the handle with the fingers.

thuya - Soft, close-grained, reddish-brown wood with a mottled figuring, imported from Africa and the USA and sometimes seen in veneers and inlaid decoration.

Tiffany & Co - Leading American jewellery firm founded 1837 in New York by goldsmith Charles Tiffany (1812-1902). The firm gained an international reputation for jewellery, especially diamonds, watches, gems and silverware. It introduced the sterling standard to the USA in 1850, which was later legalised for American sterling silverware. In 1886, Charles Tiffany designed the Tiffany setting with curved prongs to secure a solitaire diamond to a finger ring. Charles's son, Louis Comfort Tiffany (1848-1933), founded an interior design company in New York in 1879 which later became Tiffany Studios. In 1880 he patented favrile glass and for the next 20 years produced art, mosaic and stained glass pieces as well as art nouveau vases, bowls and lamps with glass shades. From 1902 he concentrated on jewellery, and also produced pottery and designed furniture, wallpapers and fabrics in art nouveau style. The studios closed in 1932, but Tiffany & Co still operates.

Tigerware - See salt-glazed stoneware.

Tigerwood - See zebra wood.

Tiles - Decorated ceramic slabs for roof, wall or floor decoration. maiolica tiles of 15thC Italy were designed for flooring, but their bright colours inspired Spanish and Portuguese pictorial wall tiles. The Dutch produced monochrome blue and white or manganese purple and white wall tiles which were exported throughout Europe from the 17th to 19th centuries. Key centres for decorative tiles in Britain were bristol, lambeth and liverpool from the late 17thC, and in France, rouen, nevers and Lisieux. In Germany and other parts of central Europe, tiles with incised or relief designs, covered with a green, yellow or brown lead glaze were made by the Hafner (stove-makers). Demand for decorative tiles fell in the early 19thC, but revived in the mid-century. The British output came from Staffordshire potteries, particularly minton. The medieval technique of making encaustic tiles, in which tiles are inlaid with clays of contrasting colours and fixed with heat, was also revived. At the end of the century glazed tiles were made in arts and crafts, aesthetic and art nouveau styles.

till - Locking compartments for keeping money, fitted into a medieval chest or casket - the forerunner of the drawer in a chest of drawers.

timepiece - Any timekeeping device, generally used to indicate one that does not strike the hours or quarters.

tin - Soft, brittle, silvery-white metal usually combined with other metals to make alloys such as bronze and pewter. Tin is also used to line other metals in a process known as tin-plating. This gives a rust-resistant finish or a protective covering to the interiors of brass or copper vessels.

tin toy trademarks - Initials or trademarks used by the most important makers of mechanical toys from the late 19thC. Some companies such as Bing, Carette and G¸nthermann, changed their marks from time to time, making accurate dating possible. Trademarks were applied in a variety of ways: stenciled or rubber-stamped on the body; applied as a transfer, a printed tin-plate lozenge or embossed brass plate; or impressed directly onto the body of the toy.

tin-glazed earthenware - Earthenware coated in an opaque white-ground glaze. The addition of tin oxide to a basic lead glaze resulted in an impermeable, more refined, white surface than previously achieved in the West. Tin glazes were used almost exclusively on earthenware, but were occasionally used by porcelain-makers to whiten a cream body, such as at chantilly c. 1730 and chelsea c. 1745. Tin-glazed earthenware was first made during the Mesopotamian civilisation, c.1000bc, but did not reach western Europe until the 8thC, when Moorish invaders introduced the techniques to Spain (see hispano-moresqueware). From the 13thC Italians began to develop their own style of tin-glazed earthenware which became known as maiolica; the French followed suit with their version, faience, the Germanic countries with fayence, and the Dutch and British produced delftware. Colours for decorating tin-glazed earthenware were at first limited to high-temperature colours. From the 18thC, enamel decoration was sometimes added after the tin glaze had been fired, and a second, lead glaze or kwaart was applied to give a brighter finish.

tinder-box - Wooden or metal box used from the 15th to 19th centuries for keeping tinder for fire-making. The box may be pocket-sized or larger for household use, and also contained a flint and steel for making sparks and sometimes brimstone matches for transferring the flame. Some 16thC boxes have a wheel-lock mechanism for producing sparks.

toaster - Long-handled toasting fork for holding bread, muffins or other food over an open fire from the 16thC. The toaster became increasingly popular from c.1720, and sometimes had a telescopic facility or a fitting for resting the fork on the bars of a grate or fender.

toasting glass - Tall, slender-bowled wine glass with a very slim stem used for drinking a toast, and made in Britain c. 1725-1800. Its capacity is 2-4 fl oz (50-115 ml). A toastmaster's glass dating from c. 1725-50, is similar but has a thickened base and sides allowing a capacity of only Ω-æ fl oz (15-20 ml), to ensure that the toastmaster remains coherent. See lglasses, drinking.

Toby jug - Earthenware jug shaped like a figure, usually a seated stout man in 18thC dress wearing a three-cornered hat. Recognisable Toby jugs were first made c. 1760 at Burslem, Staffordshire by Ralph Wood. Some female versions are known as Martha Gunn.

toddy - Stronger form of punch; drinking vessels for toddy are usually smaller than those for punch, and date from the late 18th to mid-19th centuries. A toddy lifter was used to transfer the punch from bowl to glass. Shaped like a miniature decanter with a slim neck, a bulbous body and a hole at either end, it operates on a siphon principle. A quantity of punch is drawn into the lifter by immersing the bulbous end into the punch, and closing the thumb over the neck hole. When the thumb is released, the liquid pours out.

Toftware - Late 17thC decorative slip-ware dishes made in Staffordshire by Thomas Toft (d. 1689) and others. The designs are executed in a naive style in brown and white slip. toile 1 Basic dress pattern made of muslin. 2 Linen cloth, or in the late 19thC, a fabric of silk and linen. 3 The pattern of a piece of bobbin lace. 4 Toile du Jouy is a printed cotton fabric made in France in the late 18thC, usually printed with romantic, figurative scenes in either red or blue on an ivory ground.

Tokyo School of Art - Japanese group of artists founded 1887 by Ishikawa Komei. The school was influenced by Western art and art schools while retaining the traditional skills of Japanese craftsmanship.

toleware - Name from the French tÙle peinte ('painted tin') for small objects of hand-painted tin-plate such as boxes, trays and

coffee mills. The technique originated in France c. 1740. Toleware was mass-produced from the 1760s into the 19thC in Birmingham and elsewhere in Britain.

Tompion, Thomas - (1638-1713) British clock and watch-maker who gained international recognition for his outstanding mechanical skills and craftsmanship. He was established in business by 1671, and was the first clock-maker to employ a system of serial numbers to identify timepieces. His system was continued by his successor in the business, George; graham. From 1674 Tompion worked with the British scientist Robert Hooke on various timekeeping improvements, including the balance spring, which helped to give the English a technical lead in watchmaking.

tooling - Work or ornamentation done with tools; especially stamped or gilded designs on books or leather.

Top-plate - The watchmaking equivalent of the back plate in a clock, so-called because a watch movement is assembled face down.

topaz - Precious gemstone, ranging in colour from white through to sherry-brown and blue. Orange-red varieties are the rarest and most highly prized. Pink or 'rose' topaz is the result of heat treatment applied to yellow topaz. Topaz is hard and polishes well, but it is highly susceptible to cleavage or splitting. It is usually cut as ovals or oblongs and is often confused with the abundant and less valuable citrine.

torchËre - Portable stand for a candle, also known as a candle-stand. TorchËres, can be in the form of standards to place on the floor or, especially from the mid-18thC, small enough to be set on a dressing or writing table.

tortoiseshell - Dark brown, mottled shell of certain species of sea turtle which can be moulded by heating, and thickened or enlarged by joining pieces together under pressure. It was especially popular for inlaid decoration on English and French furniture in the 17th, 18th and early 19th centuries (see boulle) , and for jewellery inlaid with piquÈ work in Britain in the 1860s.

tortoiseshell glass Mottled brown art glass developed in Europe and the USA c. 1880. It is made by rolling a gather of clear molten glass over broken pieces of brown glass, adding a yellowish-brown stain.

touch mark - See pewter.

touchpiece - A pierced coin hung from the neck of a supplicant at a touching ceremony. A piece touched by the monarch was thought to be a guard against disease.

Tourbillon - ee breguet.

Tournai - The leading porcelain factory of the Low Countries, from its foundation in 1751 to the end of the 18thC. It produced soft-paste porcelain tableware very much in the style of French porcelain of the time, particularly that of sËvres. Exotic birds, naturalistic flowers and pink monochrome landscapes are characteristic themes. Some of the figures made, particularly those left 'in-the-white', are similar to derby figures. In the 1790s, the factory merged with the nearby St Armand-des-Eaux which made reproductions of 18thC porcelain while Tournai made household wares until the mid- 19thC.

toys - 18thC English term for small ornamental objects and novelties crafted in materials such as porcelain, silver or gold, ivory or tortoiseshell. miniature ornaments, seals, scent bottles, decorative knife handles, thimbles and pomanders, for example, would be typical gifts bought from the 18thC 'toyman'.

tracery - rchitectural term dating from the 17thC and used to refer to the carved, ornamental stone openwork which decorates the top of a Gothic window. It is also found on vaulted ceilings, doors and panels. Tracery was used extensively during the first half of the 19thC on the backs of chairs and hall seats.

trader's token - An unofficial coin issued by an individual or company to supply a local need for small change.

trailing - See threading.

train - In clocks and watches, the series of wheels and driving pinions linking the source of power (a weight or a spring) to the hands, the strike or other end-function. A clock or watch may have a single 'going train', or may also have a striking, musical or alarm train. See box below.

transfer-printing - A method of printing onto solid objects such as ceramics and glassware which made the mass production of designs possible for the first time. Invented in Britain in the mid- 18thC, it was not used widely in continental Europe until the 19thC. The process involves taking a tissue print from a copperplate engraving, and transferring this to the receiving object. In ceramics this can be either over or under the glaze. Designs were initially monochrome, sometimes coloured in later. Multicoloured transfer-printing did not become established until the 1840s. A form of transfer-printing called bat-printing was used in Staffordshire in the early 19thC. The designs were transferred to the glazed earthenware by means of a flexible sheet - or bat -of glue or gelatine.

Transitional - Chinese porcelain, mostly blue and white, produced in the Transitional Period (c. 1620-80) covering the last two decades of the ming dynasty and the beginning of the qing dynasty. Imperial orders disappeared with the internal warfare following the fall of the Ming dynasty and were only partly replaced by orders from the scholar-gentry class. This move is reflected in the proliferation of wares for the writing table such as cylindrical brush pots and in painted decoration depicting more expansive landscapes and everyday rather than imperial scenes. Exports to the West were limited and were mainly of kraak porselein.

translucency - The term for the degree to which a substance such as porcelain or glass allows light to pass though it (thickness permitting) and the quality or colour of that light on passing out of the body.

treasure trove - Hidden or buried money, or precious objects whose owner is unknown.

treen - Derived from an old word for 'wooden', the term refers to small domestic articles made of turned or carved wood, such as bowls, platters and spoons.

Trembleuse - Silver or ceramic cup and saucer, fashionable in the 18thC, with a central raised ring in the saucer to hold the cup firm.

trencher salt - See salt.

trestle table - The earliest form of dining table, consisting of planks of wood held together by cross-bearers on the under-surface, and initially rested, unfixed, over two or more folding supports, or trestles. In the 16thC trestles were fixed to the table top. Trestle tables were reintroduced as part of the early Victorian gothic revival.

trial - An experimental coin, banknote or stamp, possibly of unfinished design, and often struck or printed on a material different to that intended for circulation.

Tribe, Paul - (1883-1935) French caricaturist and designer of jewellery, furniture, textiles and other interior furnishings. Tribe began working in a flowing art nouveau style, but his later, simpler forms influenced the art deco movement. He is noted for well-upholstered furniture with fine carving or inlaid woodwork. In the early 1900s. Tribe worked with French fashion designer Paul Poiret and from 1914 for American film director Cecil B. De Mille. In 1930 he went to Paris and made jewellery for Coco Chanel.

tricoteuse - Term used to describe a small, 19thC French work table with a rail bordering the edge. The term is from tricoteur 'knitter'.

tripod table - Small-topped table supported on a slender pillar and a tripod of outward-facing feet. These were popular occasional tables and for serving desserts and tea in the 18thC Georgian period. Some versions have a top that snaps or folds down vertically over the supporting pillar. See birdcage.

trivet - Wrought-iron stand with three or four legs on which to place pots or kettles taken from the fire.

trompe líoeil - Decoration on a flat surface that appears three-dimensional. The term is French for 'deceive the eye'.

troy weight - Traditional weight system used by goldsmiths, silversmiths and jewellers from 1526. The name comes from the

town of Troyes, France, and was probably brought to Britain by Henry V, c. 1420. The basic unit is the troy ounce (oz), divided into 20 pennyweights (dwt); 12 troy ounces make one troy pound (lb). A troy ounce is about 10 per cent heavier than an ordinary (avoirdupois) ounce. In some auction catalogues weights are quoted in troy ounces and decimal fractions. Troy weight is still used but metric grams are now taking over.

trumeau mirror - See pier.

trumpeter clock - A clock similar in design and appearance to the cuckoo clock, but with a model military bugler sounding a trumpet on the hour or quarter hour. The trumpet sound is operated by bellows. Another variant on the theme is a clock with mechanically played drums.

Trussel - See die.

Tsuba - The metal hand guard on a Japanese sword or dagger, often finely decorated. See kodogu.

tube lining - See slip.

tubular steel furniture - Furniture with a tubular steel framework, generally chromium plated. The earliest tubular steel chair was designed by the Hungarian Marcel breuer in 1925 and made by the thonet Brothers of Vienna.

Tudric - Trade name for table and decorative ware of pewter marketed by the London retail store liberty during the early 20thC to accompany its cymric silver range. Many of the Celtic-inspired art nouveau designs were created by Archibald Knox (1864-1933).

tulipwood - Hard, heavy wood, yellowish-brown with a pinkish tinge, from Central and South America. It was used for decorative veneers and banding during the 18th and early 19th centuries, especially on 18thC French furniture. See rosewood.

tulwar - The most common type of Indian sword, usually single-edged and often curved. The hilt is entirely metal with a flat disc-like pommel.

tumbler - Flat-based drinking glass with neither stem, foot nor handle. Tumblers are variously shaped and sized, but unlike beakers never have a flared mouth. In the 17thC, heavy metal tumblers with curved sides were designed to tumble back to an upright position if set down awkwardly.

Tunbridge ware - Articles such as trays, table tops, tea caddies, picture frames and games boards, decorated with a low-cost, mass-produced marquetry developed at Tunbridge Wells, Kent,in the mid-17thC. Rectangular-section rods of various woods were glued together then cut across in thin slices to produce a multi-coloured veneer. A similar technique was used in the 19thC for small stickwork articles, such as egg cups, turned on a lathe.

tureen - Circular or oval, deep, covered bowl of porcelain, pottery, silver or silver plate, made from the early 18thC for serving soup, sauce, vegetables or stew. Sauce tureens are smaller, plainer versions.

Turkish knot - See carpet knots.

Turkish style - An exotic furnishing style developed in mid-19thC Britain for the comfort of smokers. It drew inspiration from Middle Eastern themes probably because Turkey was associated with fine tobacco. The characteristic elements include fretted and arcaded woodwork; small four, six or eight-legged japanned tables inlaid with mother-of-pearl; upholstered chairs incorporating a panel of Oriental carpet; pierced brass incense burners and lamps. At first, the style was confined to the smoking room, but in the 1880s, as smoking became more widely tolerated, the Turkish corner became a popular feature in the drawing room. It centred on a high-backed corner divan seat with an Eastern-style canopy and frame.

Turkoman (or Turkman) - Generic name for nomadic tribesmen from central Asia known for their fine weaving. Turkoman carpets have a woollen pile and usually a red and black colour scheme.

turning - The shaping of wood and other materials such as metal and ivory on a lathe. The material is clamped onto the lathe and rotated, or turned, at an even rate while the craftsman shapes it by cutting or filing, so producing a symmetrically carved object. Wood turning has been a principal decorative effect on furniture since medieval times and developed particularly during the late 16th and 17th centuries. Different woods are more or less suited to turning but the introduction of high-speed, power-driven lathes in the 19thC enabled virtually any wood to be turned in a greater variety of shapes, and with a more uniform and symmetrical result than that achieved by the hand or foot-operated lathe.

turnip watch - See farmer's watch.

turquoise - Blue-green gemstone widely used, cut en cabochon (see jewel cutting), in 19thC jewellery. Turquoise probably takes its name from the French for Turkey, from where it first reached Europe. The bluer the colour the more prized the gem - the best-quality stones come from north-east Iran.

turret clock - A clock with its dial on the outside wall of a building and its movement inside.

twill - Fabric in which the weave forms diagonal, herringbone or diamond lines. The weft passes over two or more, and under one or more warps.

Twist - Form of decoration in the stem of a drinking glass, popular in the second half of the 18thC and revived in the 19thC. White or coloured glass rods are trapped in the glass while it is still in a molten state and then twisted. An air twist is a twisted air channel in the stem.

tyg - Two or three-handled drinking vessel, also known as a loving cup, usually large and of ceramic or silver, for passing from guest to guest at the end of a banquet. The term is loosely used for any two-handled cup. Earthenware tygs with slip decoration and sometimes initials or dates as part of the design, were common in the 17th and 18th centuries.
