The gold found in pulled or discarded fillings, bridges and casting molds can be collected by dentists and sent to a recycler. The purity of dental gold is usually 16 karat, but it is slightly more complicated to recycle than jewelry because it may include nonmetal content like tooth enamel or porcelain.
Gold has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. Today, most of the gold that is newly mined or recycled is used in the manufacture of jewelry. About 78% of the gold consumed each year is used in the manufacture of jewelry. Special properties of gold make it perfect for manufacturing jewelry. These include: very high luster; desirable yellow color; tarnish resistance; ability to be drawn into wires, hammered into sheets or cast into shapes.
