Summary edit
| Description |
English: Lime kiln at South Barn. Most of the locally quarried limestone was, and still is, used for buildings and as aggregate, but limestone was also burnt in large kilns like the restored one here to produce quicklime (calcium oxide). A mixture of coal and limestone would have been fed into the top of the kiln and pass through the mixture that was already burning. It would be converted to quicklime, which would be shovelled out at the bottom. Addition of water produces slaked lime (calcium hydroxide) which could be applied to the soil to neutralise acidity. Quicklime is also used to make lime mortar and this has been used here to restore the kiln. A slurry of quicklime was also used as a lime wash to cover external and internal walls of buildings. |
