Brass is known to humans since prehistoric times, much before zinc itself was discovered. Previously, it was produced by melting copper with calamine, a zinc ore.
Brass is a yellowish alloy of copper and zinc in which small amounts of other metals are also present. Usually 67% copper and 33% zinc is present in brass. Polished brass finish is bright, shiny involving lacquer and polishing compounds. Difficult to perfect, polishing true brass is a unique art requiring skill and expertise. It is impossible to imitate finish using paint or other less intensive processes. Brass polished products have gold like appearance.
