High Pure Quartz Vacuum Crucible Furnace for Metal Melting

Crucible - Wikipedia

A crucible is a container that can withstand very high temperatures and is used for metal, glass, Crucibles used for copper smelting were generally wide shallow vessels made from clay that . These are triangular vessels made on a wheel or within a mould using high alumina clay and tempered with pure quartz sand.
