MORTAR & PESTLE

 A pestle and mortar is a lab device used to prepare ingredients or substances by crushing and grinding them into a fine paste or powder. The mortar is a bowl, typically made of hard wood, ceramic, or hard stone, such as granite. The pestle is a heavy and blunt club-shaped object. The substance to be ground, which may be wet or dry, is placed in the bowl of the mortar, where the pestle is pressed and rotated onto it until the desired texture is achieved. Alumina mortar and pestle is chemical resistant and can be working over 1000 C. Pestles and mortars have been used in cooking up to the present day; they are frequently also associated with the profession of pharmacy due to their historical use in preparing medicines. They can also be used in masonry and in other types of construction.
