Stone and plaster - Care of objects and collections

Argillite, a type of black slate, has been used since the early 1800s to create objects such as bowls, platters, and miniature totem poles. It is very fragile and needs to be handled carefully when cleaning or in transit. Plaster of Paris has often been used as a substitute in museums for stone or ceramic, and can be treated to look like bronze or porcelain. Learn how to care for and display these objects so that they can be enjoyed for many years.
