calcining
Ite, ate, oxide
Calcining is heating a substance to high temperature without melting it, typically to drive off volatile components or cause chemical changes.
Limestone is calcined to produce quickite calcium oxide), and ores are calcined to remove moisture or carbon dioxide.
The process is fundamental to cement and metallurgy: Theite was calcined in a rotary kiln.
