Goyt Lane field kiln

Lime from the Buxton area brought down Goyt Lane and coal may have been from the Wildmoorstone Clough workings.
Loaded from above, heated initially heated gently to dry off and then heated fiercely to calcine the limestone the draught being controlled by partially blocking the stoke hole.
Calcining usually took 36 to 48 hours and then a further 48 hours cooling down.
After cooling the quick lime (CaO) was raked out. These field kilns have no waste heaps because normal agricultural practice was to spread both the lime and ashes onto the fields. It was only commercial kilns that separated out a purer product.
The quick lime was dispersed in the fields in small heaps, often covered with earth and left to slake, producing a powder and ploughed in.
The slaked lime was also mixed with riddled ashes and limestone dust to make a mortar.
