A watch glass is a concave piece of glass in circular form. They are used for a variety of utilitarian purposes, including evaporate liquids, heating small amounts of substances, coving petri dishes or beakers or holding reagents for weighing.

Watch glasses get their name as they have similarities to the glass used in old pocket watches.

When used as an evaporation surface, one will be able to observe crystallization or precipitates and they are often placed on a colored surface to provide a contrast to aid in observation.

Another popular use is to cover whiskey glasses to concentrate aromas and prevent spills when swirling the whiskey.
