Pot metal is a slang term used to refer to cheap metal alloys with a low melting point. The low melting point makes this metal very easy to cast, but the generally low quality can cause problems during casting and at a later date. There is no formal definition of pot metal, so it can be hard to determine its contents. Some common metals included in such alloys include zinc, lead, copper, and tin, among others.

The mixed contents of pot metal make it highly unpredictable, which can be a problem for people who are trying to create specific items. It has a tendency to become very soft and porous, and over time, it is subject to deformity. Pot metal also tends to break or bend easily, making it unsuitable for many tasks, and because some of the metals commonly included are toxic, pot metal can also be hazardous to human health.

Rapid and easy casting is the primary advantage to pot metal. No sophisticated foundry tools are needed, as comparatively low temperatures are needed to turn it into a castable liquid, and specialized casts and molds aren’t necessary either. Some people like to use pot metal to play around in the foundry, experimenting with molds and ideas before using metals of higher quality, and this metal can be useful in the production of some items.
