A mortar and pestle is a set of tools for grinding substances to powder. The mortar is a hard, deep bowl; the pestle is a club, which does the grinding. They are usually found together, with the pestle in the mortar. Mortars and pestles are period charges: the illustration is from the arms of Wakerley, mid-16th C. [Bedingfeld 58]. See also bowl, cup.
