"Limekiln at Reay", watercolour, 16 x 26 cm Limekilns are found in limestone country, where the soils are thin, and they were used to produce fertiliser. The limestone was burnt at high temperature to produce lime, which was then mixed with water to produce quicklime. When it was spread on fields, it reduced the acidity and improved the fertility.
