Burning of Lime

Limestone is burnt in clamps or kilns. Fuel used is generally, coal-dust or fire-wood. Cowdung or litter should not be used with kankar. A clamp consists of a heap of limestone and coal stacked in alternate layers and is used for burning only small quantities of lime as it is a wasteful method.

out of 100 parts of pure limestone burnt, only 56 parts of lime are left behind.

After burning kankar lime it should be ground without delay as it deteriorates rapidly if left unground during the rains. The limes (both kankar and white lime) after being ground dry should be carried to the site of work in gunny bags, and not dumped or stacked on the ground.
