After an event you can either crush limestone or burn it in a kiln. If you burn it in a kiln you will need to slake it with water. It will then give off a great deal of heat. Be careful you do not get burned. Once it has been slaked you can use it on the garden or make lime mortar with it. If you don't have limestone you can use chalk. Burn in a kiln and slake with water as above. Be careful. Kenneth Eames.
