Abacus
AbacusThe precursor to the pocket calculator is still sometimes found with wires across it, each threaded with ten beads. It is at least as old as the ancient Greeks (abacus is Greek for ‘cyphering table’), since it can also be used to teach writing and later modified by the Chinese. Crude examples from British schools and nurseries are common enough.
 
It is also used as a furniture term for a Roman sideboard, adopted from Asia where it was originally introduced around the 2nd century B.C.
 
 
Abalone
Abalone Shell
Abalone are small to very large-sized edible sea snails, marine gastropod molluscs in the family Haliotidae and the genus Haliotis. Common names for abalones also include ear-shells, sea ears, as well as muttonfish or muttonshells in Australia, ormer in Great Britain, perlemoen and venus's-ears in South Africa and pāua in New Zealand.
 
The shells of abalones have a low and open spiral structure, and are characterized by several open respiratory pores in a row near the shell's outer edge. The thick inner layer of the shell is composed of nacre or mother-of-pearl, which in many species is highly iridescent, giving rise to a range of strong and changeable colours, which make the shells attractive to humans as decorative objects, and as a source of colourful mother-of-pearl, which is used in jewellery making.

The flesh of abalones is widely considered to be a desirable food, and is consumed raw or cooked in a wide variety of dishes.

The haliotid family has a worldwide distribution, along the coastal waters of every continent, except the Atlantic coast of South America, the Caribbean, and the East Coast of the United States.
 
Abbotsford Furniture
Extravagant neo-Gothic furniture made during the 1820 – 30’s and named after the baronial house of Sir Walter Scott. It is heavy and spiky, and sometimes crudely made up from genuinely old fragments. The architect A.W.N. Pugin while admitting that he had designed such stuff for Windsor Castle, said of it ”All the ordinary articles of furniture which require to be simple and convenient, are made not only very expensive, but very uneasy.... A man who remains any length of time in a modern Gothic room, and escapes without being wounded by some of its furniture, may consider himself extremely fortunate.”
 
 
Abbotsford Ware
Brilliantly decorated pottery in the Wemyss style produced by the Fife Pottery’s neighbour and rival, the Kirkcaldy Pottery of David Methaven & Sons in the late 1800’s and early 1900’s. It is more likely that the two establishments used the same decoratons – all the owners were cousins. However Abbotsford does not seem to have produced the large pigs which are the best-known Wemyss products. The pottery had no connection at all with Sir Walter Scott – except to prove how bankable his name still was 70 years after his death.

Acanthus
AcanthusAcanthus is a classical ornament in the form of a stylised leaf decoration based on the scalloped leaves of the acanthus plant. Acanthus is the most prolific foliage to flourish as a decorative motif on architecture, furniture and works of art. Derived from the Mediterranean, in the hands of artists it can also resemble thistle, poppy or parsley leaves.
 
The acanthus leaf has been a motif that has continued in use for centuries. The use of acanthus leaf as decorative motif of a stylized leaf originated in ancient Greece where it was used as an architectural motif particularly on Corinthian capitals. Even Gothic and Romanesque architects and craftsmen employed it and from the Renaissance to the mid 1800’s it was constantly in favour. Eventually one critic was complaining of the inevitable scanthus leaf as if in the whole range of vegatable life this was the only kind of foliage worth imitating, and another that it requires so little thought.

Today the acanthus leaf motif is found most commonly on case goods, but you will find it in upholstery fabric patterns as well.
Acanthus 4It gained much popularity during the French Louis XVI period, and is still used to give a rich opulent touch as in this mirror frame from Pulaski. When you look at the gentle curves of an acanthus leaf you will understand why it has been such a favourite in carved, painted or gilded furniture. On textiles it can be woven embroidered or printed.

William Morris was an artist associated with the Arts and Crafts movement, and is famous for his textiles and wallpapers among other things.

Aesthetic Movement
Aesthetic Movement
 
 
 
 
This might be called the ’arty’ end of the Arts and Crafts Movement. It was a reaction to the flamboyant ornamentation loved by the Victorians. From the 1840’s a new purity of design was championed by Pugin and Owen Jones, and in the 1860’s the idea of Art for Art’s Sake was taken up by the culturally aware. The Movement drew on diverse sources from Japanese and Chinese to Queen Anne and traditional metalwork. Walter Crane summarised it well in 1889: ”plain material and surfaces are infinitely preferable to inorganic or inappropriate ornament.”

American Clock
American Clock
 
 
 
 
The term American clock was used in the Victorian era and afterward to refer to a particular style of clock design followed by the American clockmakers of the day.

In the 1800´s, many clocks and watches were produced in the United States, especially in Connecticut, where many companies were formed to mass-produce quality timepieces.

The most commonly found American clock in Britain is the mass-produced late 1800’s wooden wall or mantel clock by the American Clock Co. They may have pediments or flat tops and painted or transfer-decorated panels below the dials. However during the same period American makers were capable of better quality, and more impressive items.

Andirons
AndironAndirons are the forerunners of the fire basket and consist of two large wrought iron or cast iron supports for logs that stand in a hearth to contain logs. They were made in pairs from the 1400’s to 1700’s when coal replaced wood for heating most houses. They are vaguely dog shaped with upright stems usually on two feet and horizontal backs running to a hind foot. Their fronts are often made of reflective material such as silver, brass, polished steel or paktong. Most are simple and rustic, but great houses had grander versions in bronze, brass or even silver. Many of these were purely decorative and were replaced with smaller, humbler versions for actual use.
 
Andiron may be derived from Endiron, describing the end iron in the hearth.

Aneroid Barometer
Aneroid Barometer
 
 
 
 
 
 
A Frenchman, Lucien Vidie, invented the aneroid barometer in 1843. He produced a metallic barometer that he called an aneroid, from the Greek, meaning “without liquid”, and this form of barometer is so called because it uses atmospheric pressure on a partial vacuum rather than on mercury. The invention goes back to Leibniz (1646-1716), but its first commercial use was by Lucien Vidie, and his competitor Eugine Bourdon in the mid 1800’s.
 
 
The principle of the aneroid barometer is the change in height of a sealed metallic chamber that has flexible upper and lower surfaces. As the pressure changes, so the height of the chamber varies which, in turn, moves an index pointer. As there was no need for a long tube of mercury, it was possible to build a compact instrument. Aneroid barometers are less susceptible to shock and the transport problems associated with mercury instruments. All movements are tested and calibrated to sea level. Instructions are included so the instrument can be adjusted for height variations above sea level, as forecasts quote the sea level pressure, shown in isobars on a meteorological chart.
 
Desk or mantel versions with visible workings were popular, and pocket types were also made in many sizes with gold, silver or brass cases. They should not be confused with anemometers or wind gauges.

Annealing
Annealing is the process of heating a metal and then cooling it to make it more workable.

As metal is worked, hammered, rolled, forged etc. the stresses make the metal brittle (the metal molecules are pulled into random structures during the working). Annealing the metal make the metal re-crystallize, putting the molecules in an orderly structure.

The temperature and amount of time it takes for annealing a metal depends on the metal or metal alloy. Large pieces are annealed in an annealing oven; small pieces are annealed using a blowtorch.

Annealing is also used to remove tension in a piece of metal before brazing, helping to reduce warpage.

After annealing, quenching is not necessary but may be of advantage in helping to remove scale.

Anode Copper
Cast slabs of copper from the fire refining processes used as starters for electrolytic refining.
 
 
Anodized
Anodized metal has been through an electrochemical process that changes the molecular structure of the surface layer, giving it a thin, protective film.
 
In the anodization process, the metal is placed in an acid bath (at the "anode" or positive end of the electrical circuit) and an electrical current is passed through the tank. This process causes a controlled oxidation of the metal's surface to occur (oxygen atoms bond to surface atoms of the metal).
 
Aluminium is often anodized, as is magnesium, titanium, and tantalum.
 
Anodized metal has a lustrous sheen; the anodizing process can produce colourful surfaces.

Arts & Crafts
Arts & CraftsA group of 1800’s artists and designers, led by William Morris, who tried to restore interest in simple hand-craftsmanship, in direct conflict with the with the Victorian taste for over embelishment.
 
The Arts and Crafts was an artistic movement that produced hand-crafted pieces toward the end of the 1800's. The movement, led by William Morris and his artist and designer companions in UK, which sought to challenge increasing industrialisation by re-introducing the medieval concepts of craftsmanship. Pieces purposely look hand-made, incorporating hammer marks and simple cabochon settings. The Arts and Crafts movement also revived the art of enamel.
 
A prominent Arts and Crafts jeweller was C.R. Ashbee (1863-1942); Ashbee founded The Guild of Handicraft in 1888.
 
Other important Arts and Crafts jewelers include:
  • Arthur Gaskin (1862-1928)

Auction
Victorious Roman armies used to divide their loot, and slaves, by auction. In Britain the first record of auctioneering comes only at the end of the 1400’s, with an official of Henry VII’s court known as the King’s Over-Roper. To rope was to shout out for sale and the word survives in Scotland and northern England where sales may be called ’roups’. After the restoration of Charles II in 1660, auctions became common in London, with Covent Garden as the centre of trade. Amongst the oldest British firms to have survived are Sotherby’s which stems from Baker’s book sales beginning in 1744, and Christies, founded in 1766. Dreweatt Neate of Newbury also has its origins in the 1760’s. Bonhams, which in part is still a family run firm, and Phillips, founded by James Christie’s sales clerk, followed at the end of the 1700’s.

Bakelite
Bakelite, also called catalin, is the trade name for a dense, synthetic resin, phenol formaldehyde or phenolic, developed by the German chemist Leo Baekland and patented in 1907.
 
This hard non-flammable plastic could not be remoulded once set. It had a limited colour range, principally mottled brown or black, but also blue and green. When one Bakelite colour is inlaid into another, interesting designs like polka dots can be made.
 
Bakelite plastic is made from carbolic acid and formaldehyde, and when rubbed, Bakelite gives off benzene like smell.
 
Bakelite became popular in the 1920’s and 1930’s when it was used for domestic items, jewellery and electrical fittings.
 
Bakelite pieces are moulded, extruded, or carved.
 
Bakelite was first used to imitate amber.

The bamboo form as a leg or otherwise was popular during the influence of Eastern designs in 1740-1760, and again at the turn of the 1700´s into the 1800´s. It took the form of clustered columns in mahogany furniture, with small double collars turned to look like bamboo joints, or, later, single columns so turned. In the Regency period actual bamboo reproduction was made in other woods (or even iron). Bamboo furniture itself tends to be a Victorian manufacture, since much bamboo furniture was produced in the late 1800´s perhaps as a feature of the heyday of Empire.

Decorative feature of furniture where strips of veneer run around the edge of panels.
 
Used around the edges of tables or drawers for decorative effect, the art and proportion of the banding is vital to the success of the design. Straight banding is one which has been cut along the grain; crossbanding describes that where the wood has been cut across the grain.
 
Very decorative effects were obtained by using different and exotic woods for cross-banding. Herring-bone or feather bandings were used in walnut furniture.

Barometer
Barometer 1Barometers are used to measure atmospheric pressure.
 
Galileo¨s notes on measuring pressure were discovered after his death by an apprentice called Evangelista Torricelli (1608 – 1647) who improved on the master by using mercury instead of tubes of water. A scale was added to his first barometer only after his death, by the French philosopher Descartes.

Barometers were introduced to Britain in the 1680´s, in both the basic stick and the wheel types. The stick, which stands on three little legs, was popularised by the Irish scientist Robert Boyle (1627 – 1691). It had a visible vacuum at the top of the mercury column. The wheel type, invented by Robert Boyle¨s assistant, Robert Hooke (1635 – 1703) has a U-bend at the bottom of the tube.
 
In the 1800¨s, Clerkenwell was full of Italian barometer-makers as well as clockmakers. One of the most common mid to late 1800¨s types is the Fitzroy, invented by the commander of the Beagle on Charles Darwin¨s South American voyage. Most Fitzroy barometers have Victorian Gothic oak frames

Basse-Taille
Basse-taille, meaning "low cutting" in French, is an enamelling technique in which the underlying metal, usually gold or silver, is carved in low relief (the metal's surface is cut away by engraving or chasing, producing a sculpted surface). The highest point of the relief carving is below the surface of the surrounding metal. Translucent enamels are applied over the carved metal, allowing the design to remain visible through the enamel. The hue of the enamel changes with the depth of the glaze, resulting in subtle variations in colour over the high and low design elements.

Biedermeier
Derived from the name of a political caricature appearing in a German newspaper, who typified a well-to-do middle-class man without culture. Biedermeier furniture, which was in vogue from around 1815-1825 to about 1860, was always commonplace and a potpourri of some Sheraton, Regency, Directoire and Empire features.
 
 
Biedermeier Jewellery
Following the turmoil of the Napoleonic wars, many of the countries of Europe were in financial crisis and none more so than Prussia. Precious metals were unobtainable. Gold and silver jewellery had to be surrendered to the State to further the war effort, and the State provided substitutes in iron. The link between iron and patriotism was further reinforced by the introduction of the Iron Cross as the highest military honour.
 
Between 1813 until around 1842, enterprising jewellers and metalworkers set to work and produced some remarkable jewellery made from iron and steel. The finest jewellery was made at Gleiwitz in Silesia and also in Berlin. Casting was used to make much of the jewellery, and pieces of amazing delicacy were produced, attributable so it was claimed, to the type of sand used. Other pieces such as necklaces and brooches were made by drawing out the iron into fine wire, and weaving it to make a delicate mesh.
 
The quality of workmanship in the finest pieces is astonishing and deservedly finds a place amongst the jewellery made from gold and other precious metals.

Fire Dogs
AndironAndirons or Fire Dogs are the forerunners of the fire basket and consist of two large wrought iron or cast iron supports that stand in a hearth and were used for supporting either the grate or large logs directly. They were made in pairs from the 1400’s to 1700’s when coal replaced wood for heating most houses. They are vaguely dog shaped with upright stems usually on two feet and horizontal backs running to a hind foot. Their fronts are often made of reflective material such as silver, brass, polished steel or paktong. Most are simple and rustic, but great houses had grander versions in bronze, brass or even silver. Many of these were purely decorative and were replaced with smaller, humbler versions for actual use.

Andiron may be derived from Endiron, describing the end iron in the hearth.

The pointers – one for “Yesterday”, and the other for “Today” – enabled atmospheric pressure to be recorded on successive days.
