What is slaking?
It is the process for making lime putty. Quick lime is added to water and a chemical reaction occurs resulting in the release of a large amount of heat from the quick lime creating a boiling liquid. The liquid is drained off through a sieve into a settling tank. Chemically the calcium oxide is converted into calcium hydroxide. The longer the slaked lime is matured in the tank the better the lime putty. We leave ours for around 4 months.
