What is Metal Clay? 

Metal clay is a crafting material made from tiny particles of metal like silver, gold, copper, or bronze mixed with an organic binder and water, allowing it to be shaped like traditional clay to create jewelry and small sculptures, which then needs to be fired to burn off the binder and fuse the metal particles into a solid form; essentially, it's "clay" made of metal, not dirt, that can be molded and sculpted before being hardened through firing.
