  Limestone and seashells (the latter used at the Maya ruins at Comalcalco) are calcium carbonate, which is heated to produce quicklime (calcium oxide). The quicklime is slaked under water to produce lime mortar (calcium hydroxide). When the mortar sets it becomes stucco (calcium carbonate again; the cycle is complete).
