Casting is a fundamental jewelry-making process where molten metal is poured into a mold to create jewelry pieces. It's like making ice cubes, but with precious metals - you pour the liquid metal into a prepared shape and let it solidify. This method is widely used in both small jewelry studios and large manufacturing facilities to create multiple identical pieces efficiently. When jewelry makers mention casting, they're referring to this process of transforming metals like gold, silver, or brass from their liquid state into solid jewelry pieces.
