Lime Production from a Lime Kiln
The lime kiln constructed at Hobbs was used for the calcination of the quarried limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). Slaked lime (calcium hydroxide) was formed by mixing the quicklime with water.
Amongst other uses the lime was used in the farm fields local to Gloucester. Lime acts as a soil conditioner by neutralising soil acidity, countering the effects of acids produced by nitrogen fertilisers, slurry, and heavy rainfall. Additional benefits include enhanced earthworm activity, improved soil structure, and increased palatability of grass for livestock.
