Ca(OH)2 calcium hydroxide, made from quick lime slaked in water, to form the soft buttery mixture which is lime putty.
The plastic material resulting after the lime hydration process stops and the semi-fluid mass cools off. In t his form the hydrated lime is ready to be added to masonry mortar mixes (as a plasticizer) or can be used by itself as either base- or finish-coat plaster, especially in historical restorations.
Lime, which is moistened to a puttylike texture and, when added to mortar, keeps it workable by retaining water.

Lime putty is created by slaking quick lime. A mature Lime putty should have been slaked and stored for at least 2 years to give it the cottage cheese like consistency suitable for Fresco.
