John Halliday, in his Warminster notes compiled during the 1980s, wrote:
“Lime. Made from strongly heating limestone to make quick lime, then soaking with water to form lime wash, or with sharp coarse sand, lime mortar; or finer sharp sand for plaster, often mixed with chalk (ground) and hair (cow). Lime kilns frequently found in the Warminster area. A good example on south slope of Arn Hill on old winter-used road.”
