When limestone/chalk (calcium carbonate) is burnt in the kiln it turns into quicklime (calcium oxide) and releases carbon dioxide. Water can be added to quicklime/burnt lime to produce hydrated lime (calcium hydroxide). Over the lifetime of lime products, carbon dioxide is gradually re-absorbed by lime from the air, which is known as recarbonation.
