Field lime kilns such as this well-preserved example near Long Ashes were built to burn limestone. The quicklime produced was then slaked with water to produce calcium hydroxide (slaked lime). This was mostly used to improve grassland by reducing the acidity of the soil, especially of intake land or reclaimed moorland during the enclosures of the 18th and 19th centuries. Slaked lime was also an important ingredient in making lime mortar.
