Lime And Cement Burning

Limestone is calcined (burnt into lime) in "clamps" or in "kilns" of different forms.. Clamps consist merely of heaps composed of alternate layers of limestone and coal, having a fire-hole below, and covered with clay or sods to prevent the escape of heat.. This is a very wasteful method of burning, and should only be used where limestone and fuel are abundant.

Lime and charcoal burning

Lime and charcoal burning. Considerable amounts of limestone and firewood made lime burning one of the activities with which the local people earned their living. Limestone was stacked into a special lime-kiln, called apnenica, and the fire was lit up. This released carbon dioxide and produced burnt lime – calcium oxide (CaO).
