Crucible

In chemistry, a crucible is a kind of laboratory equipment that is usually a small cup, about the size of a shot glass, made of porcelain or non-reactive metal. Crucibles are used to heat chemical compounds to very high temperatures. Metals such as nickel and zirconium are also used as a modern crucible material.[1]
