crystal
The Hebrew {kerach}, which generally denotes {ice}, doubtless here signifies crystal, [], from [], cold, ice, and [], to concrete,) as it is rendered by the LXX and Vulgate. It is a very large class of silicious minerals, hard, pellucid, naturally colourless, of regularly angular figures, and of simple plates; not flexible, not elastic, but giving fire with steel; not fermenting by acid menstura, but calcinable in a strong fire. There are three orders of pure crystal: the first is perfect columnar crystals, with double pyramids, of eighteen planes, in an hexangular pyramid at each end; the second is that of perfect crystals, with single pyramids, of ten or twelve planes, in an hexangular or pentangular column. [Terrible crystal] seems to denote that which was well cut and polished, vividly refracting the rays of light.
