Lime plaster

Burned limestone that sets back into stone.

Tool residues at Lagama North VIII in Sinai, around 14000 BCE, are interpreted as lime-plaster adhesive. By about 10000 BCE, Natufian people at Nahal Ein Gev II used high-quality lime plaster to cover burials. Lime binders later served in floors and statues, and eventually in mortar and Roman concrete.
