Meter & Pestle
A mortar and pestle is a tool used to grind and mix substances, including chemicals in a laboratory and also food in the kitchen. The pestle is a heavy small bat, made from porcelain, wood or other materials, whose rounded end is used for pounding and grinding. The mortar is a bowl, which can be made from porcelain, wood, carved stone or other materials. The substance is ground between the pestle and the mortar by rubbing or pounding the substance with the pestle against the wall of the mortar, thus turning it into a fine powder.
