Historic Masonry Workshop Overview:

Masonry is considered permanent but is still subject to deterioration, especially the mortar joints. Students learn the process of changing limestone into traditional putty for replacing these joints. They start by constructing a small kiln for burning the stone and slaking lime. Then they mix the resulting lime putty into a mortar for repairing historic masonry. This workshop provides a comprehensive study of the conservation and restoration of historic masonry by providing classroom instruction and hands-on experiences. The hands-on project is a late 1800”s historic masonry house.
