[Kavita Jain]

Lime is one of man's oldest and most vital chemicals. The ancient Romans used lime in building and road construction, uses which continue to the present day. From earliest times, lime has been made by heating limestone (calcium carbonate) to high temperatures. This process, known as calcining, results in quicklime, or calcium oxide. Hydrated lime (calcium hydroxide) is produced by reacting quicklime with sufficient water to form a dry, white powder.
