Plaster and lime kilns
Lime is a product traditionally used in construction.
Mixed with water, it was used as whitewash, and mixed with water and clay or sand it was used to plaster façades and make cisterns and tanks watertight.
Lime is calcium oxide obtained by firing calcareous stones at a very high temperature, which form what we know as quicklime.
Lime kilns, built to fire these stones, were made of well-constructed stone piles. A false dome was built underneath, forming an appropriate space for firewood to be placed.
Plaster is hydrated calcium sulfate, and is obtained through the same process as the lime. Mixed with water, it makes a paste that hardens very quickly. Plaster was routinely used in construction for coating walls, building floors and cementing bricks.
