Spelter, while sometimes used merely as a synonym for zinc, is often used to identify a zinc alloy. In this sense it might be an alloy of equal parts copper and zinc, i.e. a brass, used for hard soldering and brazing, or as an alloy, containing lead, that is used instead of bronze. In this usage it was common for many 19th-century cheap, cast articles such as candlesticks and clock cases and early 20th-century Art Nouveau ornaments and Art Deco figures.
