Calcination

Calcination – Burning Limestone. Quarried stone is crushed and transported to a lime kiln. The lime burning process within the kilns requires enough heat to be transferred to the limestone in order to decompose the calcium and magnesium carbonates. Heat transfer for lime burning can be divided into three main stages:

Lime burning | Industrial History of Cumbria

In some places the limestone was simply burnt in clamps or pye kilns, in which coal slack and limestone were burned in an enclosed heap. It was the agrarian revolution of the eighteenth century, when vast areas were enclosed for farm land, that created an enormous demand for lime which would reduce the acidity of the soil and make it more fertile.

Lime Kilns in Cumbria | Visit Cumbria

Limestone was burnt in kilns wherever fuel and raw limestone could be brought together easily. Burning limestone, which is calcium carbonate, gives you quick lime, calcium oxide. Mixed with water this produces slaked lime, calcium hydroxide. When slaked lime or quick lime was added to the land it raised its pH and so improved its fertility.
