The process of calcining.


Etymology: L, calcinare, to burn lime
the heating of inorganic materials to drive off water. It is used in dentistry to manufacture plaster and stone from gypsum. Compare calcification.


The process of heating a solid (e.g., an ore) in air below its melting point to effect thermal decomposition, phase transition or remove volatiles, thereby changing the original solid into something else—e.g., heating calcium carbonate to release CO2 gas and form calcium oxide.

calcination (kal´sinā´shən),

n a process of removing water by heat; used in the manufacture of plaster and stone from gypsum.
