CAL-CI-NA'TION, n. [from calcine.]

1. The operation of expelling from a substance by heat, some volatile matter with which it is combined, or which is the cementing principle, and thus reducing it to a friable state. Thus chalk and carbonate of lime are reduced to lime by calcination, or the expulsion of carbonic acid.
2. The operation of reducing a metal to an oxyd, or metallic calx. This, in modern chimistry, is called Oxydation.
