Stone and muller

A stone and muller is a hand-operated tool used for mixing and grinding paint. The stone and muller was popular with artists and tradesmen from the late 18th through the 19th century.^[1] A stone and muller differs from a mortar and pestle in that the former consists of two flat stone surfaces which are rubbed together to create a paste,^[2] whereas the latter consists of a bowl and stick.
