Spelter been used since about the 1860s to make statues, tablewares, and lamps that resemble bronze. Spelter is soft and breaks easily. To test for spelter, scratch the base of the piece. Bronze will appear as bright yellow while spelter will show a silvery scratch. The word "pewter" is thought to be derived from the word "spelter". Zinc ingots formed by smelting might also be termed spelter. Spelter 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.
Brass balanced composition and proper production temperatures and parameters to avoid long-term failures. The high malleability and workability, relatively good resistance to corrosion, and traditionally attributed acoustic properties of brass, have made it the usual metal of choice for construction of musical instruments whose acoustic resonators consist of long, relatively narrow tubing, often folded or coiled for compactness; silver and its alloys, and even gold, have been used for the same reasons, but brass is the most economical choice. Collectively known as brass instruments, these include the trombone, tuba, trumpet, cornet, baritone horn, euphonium, tenor horn, and French horn, and many
