    • n crucible A vessel or melting-pot for chemical purposes, made of pure clay or other material, as black-lead, porcelain, platinum, silver, or iron, and so baked or tempered as to endure extreme heat without fusing. It is used for melting ores, metals, etc. Earthen crucibles are shaped upon a potter's wheel with the aid of a templet or molding-blade, or under pressure in a molding-press. Metallic crucibles, especially those of platinum, are chiefly used in chemical analyses and assays.

LL. crucibulum, a hanging lamp, an earthen pot for melting metals (cf. OF. croisel, creuseul, sort of lamp, crucible, F. creuset, crucible), prob. of German origin; cf. OHG. krūsul, LG. krüsel, hanging lamp, kroos, kruus, mug, jug, jar, D. kroes, cup, crucible, Dan. kruus, Sw. krus, E. cruse,. It was confused with derivatives of L. crux, cross (cf.
