There are different types of casting used for different types of materials and metal. We are interested in those used to form cast silver. Silver has considerable strength and a low melting point to which makes it an ideal metal to be cast without difficulty. Here we will be looking into the technical background of the process that is casting.

Casting Silver

In its simplest form casting silver is when liquid metal is poured into a mould and is left to set until it hardens. The liquid once set takes on the form of the shaped mould. If you think about water being poured into an ice tray and then left to set; this is how casting works. The disadvantage of this is that objects were flat on one side, to get a full 2D object two halves of a mould are made symmetrically and locked together. Interestingly, due to the mould being closed ventilation holes are placed to allow the metal to set and gases to escape. Due to this sprues are left behind which have to be cleaned off the finished product produced.
