crucible,

vessel in which a substance is heated to a high temperature, as for fusing or calcining. The necessary properties of a crucible are that it maintain its mechanical strength and rigidity at high temperatures and that it not react in an undesirable way with its contents. Porcelainporcelain

Crucible

a vessel for melting, founding, or heating various materials. Crucibles are used, for example, for melting metals and alloys, for heat-treating metal objects in a controlled atmosphere or in liquid media (seeTANK FURNACE), for glassmaking, and for melting and calcining substances in the laboratory (seeLABORATORY VESSELS, CHEMICAL). Depending on the temperature of treatment and the chemical properties of the materials being treated, a crucible may be made of metal (pig iron, heat-resistant steels and alloys, or platinum), graphite, porcelain, or refractories. Crucibles are usually round in cross section and narrower at the bottom. In many industrial furnaces, materials are treated in crucibles inside the furnace itself.
