Over the last couple of months, weâve had the job of rebuilding The Grindon Limekiln near Butterton, which dates back to the early 19th century. (The kiln is at Butterton but called the grindon lime kiln)
The perimeter wall of the kiln, after standing for approximately 220 years with only a couple of repairs over time, was in need of some attention. We shored up the banks, propped the infill, and methodically dismantled it in sections before rebuilding it on a new footing. Once finished, it will include structural steelwork inside to support the inner kiln pot, as well as new brick built archways.
This design is fairly typical of limekilns from that period, which were used for the calcination of limestone to produce quicklime an essential component in construction and agriculture.
The limekiln is recognized for its historical significance and is listed as a Grade II building by Historic England. This designation highlights its importance as part of the regionâs industrial heritage.
Old fashioned lime kilns operated by heating limestone (calcium carbonate) in a chamber until it decomposed into quicklime (calcium oxide) and carbon dioxide.
Layers of limestone and fuel (such as coal, wood) were placed inside the kiln, with fuel layers providing heat.
The kiln was lit, and the fuel burned to produce high temperatures (around 900â1000°C).
The heat caused a chemical reaction in the limestone, releasing carbon dioxide and leaving behind quicklime.
Once the process was complete, quicklime was removed from the bottom of the kiln.
This process often ran continuously, with fresh layers of limestone and fuel added at the top as quicklime was removed from below.
The project will be completed in the spring, settling nicely back into its surroundings and preserving its story for future generations to see for years to come.
