"Cold-Casting" is a term used to describe the process of mixing metal powder with a resin to create castings that give the appearance of solid metal. The metal cold-cast process (also known as "bonded bronze") is faster and much less expensive compared with foundry casting of molten metal (lost wax process.) Different metal powders such as Bronze, Brass, Nickel Silver, Copper and Aluminum can be used depending on the desired effect.
