What is limestone made from

Lime is made by first burning chalk or limestone to form quick lime (calcium oxide) and then slaking the quicklime with water (forming calcium hydroxide). If no clay is present in the original limestone or chalk, the resulting lime is said to be 'non-hydraulic'. This form stiffens and eventually hardens by reacting with carbon dioxide which is ...
