Acanthus: The acanthus is one of the most common plant forms to make foliage ornament and decoration. Both Acanthus mollis and the still more deeply cut Acanthus spinosus have been claimed as the main model, and particular examples of the motif may be closer in form to one or the other species; the leaves of both are in any case rather variable in form. The motif is found in decoration in nearly every medium.
Adam Style: A Neo-classical architectural style based on the work of Robert Adam (1728-1792) and his brothers. The style was predominant in England in the late 18th century.

Alpaca Silver: Nickel silver, also known as German silver, Argentan, new silver, nickel brass, albata, alpacca, or electrum, is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. Nickel silver is named for its silvery appearance, but it contains no elemental silver unless plated. The name "German silver" refers to its development by 19th-century German metalworkers in imitation of the Chinese alloy known as paktong (cupronickel) All modern, commercially important nickel silvers (such as those standardized under ASTM B122) contain significant amounts of zinc, and are sometimes considered a subset of brass.

Brass: Brass is an alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, for plumbing and electrical applications.
Bronze: Bronze is principally an alloy of copper and tin, resulting in a more reddish tone than brass. Bronze does not necessarily contain tin, and a variety of alloys of copper, including alloys with arsenic, phosphorus, aluminum, manganese, and silicon, are commonly termed "bronze".
