Our craftspeople will stoke the lime kiln until the iron doors bend. These days, 20 sterling firewood, many diligent hands, and countless liters of sweat turn 2.2 tons of limestone into about 1.5 tons of quicklime. After three days of stewing every 10 minutes, we let the fresh piece of quicklime cool from its 1200 ° C overnight, so that starting on Sunday afternoon we can begin with the cooling down of the lime. This stock of lime lime is enough to mix 8 tons of mortar to build up our outer walls for our medieval construction site.
