Bronze Clay

Bronze metal clay was the first of the base metal clays manufactured in America in 2008. Bronze is considered an “alloy” which is a material consisting of more than one metal. Bronze metal clay consists of 11% tin, 89% copper, an organic binder and water. Because copper readily oxidizes with the air, bronze clay must be buried in carbon in order to be fired. When fully sintered or fused a solid bronze piece is created with a density of 90% that of cast bronze. Base metal clays are not considered “precious metals” and are less expensive to work with.
