Calcination is done in small saggers or clay pots with a lid.

12. Developing glazes 1993

Calcination takes place at 700° C for 3 hours, with the temperature monitored by thermocouples and controlled by an air blower and feed input.

Chapter 4 1988

Calcination takes 30-45 minutes, during which time the gypsum is turned over from time to time with a wooden rake: it is then left to cool and is bagged for sale or for block-making.

Chapter 9 1985

Calcination temperature and firing time: At any one particular temperature above the minimum necessary, the stone must remain at that temperature for a length of time sufficiently long to dissociate all the CO2 from the stone.

3. Technical and Production Information 1985

Calcination of dolomite: Dolomite is particularly difficult to fire satisfactorily since the temperatures necessary to dissociate the CO2 from the MgCO3 component of dolomite are lower than those necessary for the CaCO3 component.
