Lime plaster
A wall finish made from burnt limestone that slowly turns back into stone as it takes in carbon dioxide.
01 / Origin
Where it comes from.
Lime plaster is made by heating limestone to drive off carbon dioxide, giving quicklime, which becomes slaked lime when mixed with water. It has been used since antiquity.
It hardens in two steps: the water evaporates, then carbon dioxide from the air turns the lime back into calcium carbonate. Lime plasters were used for wall coverings, frescoes and decoration.
02 / Colour
