| **Description:** Lime is manufactured by heating crushed limestone in a very hot fire such as is produced by coal or charcoal, inside an enclosure, usually a kiln. Such a kiln takes the form of a conical stone or brick structure, open at the top to form a chimney, and with an opening at the bottom. Alternating layers of crushed limestone and, e.g., charcoal are stacked inside, usually from the top, the fire is ignited, and the bottom opening is sealed up all but an airway. The contents are left to smolder until the limestone is reduced to a whitish powder. The powdered lime is then used in other processes/products such as agriculture, concrete and glassmaking, among others. | **Description:** Lime is manufactured by heating crushed limestone in a very hot fire such as is produced by coal or charcoal, inside an enclosure, usually a kiln.
