Watch glass

A watch glass is a concave and convex piece of glass used as a surface to evaporate liquids. They are also used to hold solids, for heating small quantity of any specimens or as a cover for beakers. However, one of the generic uses of watch glass is to act as a lid for beakers. When they are used as a surface for evaporation, watch glasses determine crystals and patterns of precipitation. Glass watch glasses can also be reused after sterilization either in a laboratory oven or in an autoclave.
