Quicklime is calcined calcium carbonate or limestone. It is unstable (wants to reabsorb the lost CO2) so must be used quickly or sealed from exposure to the air. It is used as a source of CaO in the glass and enamel industries and in refractories (often in combination with calcined dolomite).

If Quicklime is calcined higher than necessary for slaking (to make calcium hydroxide) it is referred to as dead-burned lime.
