Bronze Powder: also known as gold bronze powder, is a metallic pigment made from an alloy of copper and zinc. Its shimmering gold-like appearance makes it highly desirable in various industries, including printing, coatings, cosmetics, and arts. This article explores its composition, production, applications, and advantages.
