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.

Limestone - The Bugsworth Legacy

Following the development continuous draw kilns in circa 1750 it became uneconomic for farmers to burn limestone in field Gypsumers and this practice eventually died out. However, intermittent kilns in some of the small quarries would, in all probability, have continued working and over the years these would have been replaced by continuous draw kilns as the quarries converted to properly constituted businesses.
