Lime kiln photos
Five photos of the old lime kilns in the grounds of 28 Westfield Road taken in 2018.
There were many more lime kilns than are in evidence today, the line of these extrending to where the house now sits. The lime was used for agricultural purposes and also for lime mortar. Lime in bricks can cause them to blow, see
Blowing of bnricks is caused when clay bricks contain small amounts of lime. When the bricks are fired, the lime is converted to calcium oxide (quicklime). When the bricks become wet the calcium oxide begins to slake. The process of slaking is vigorous and can cause an eruption on the face of the brick.
The blown bricks on the Old House might well have resulted from an experiment of adding lime.
