A tool used to grind or crush substances into a fine powder, often used in art studios, pharmacies, or kitchens.
From Old French 'moldre' (to grind), related to the Latin 'molere.' The tool's name describes its primary function of grinding or pulverizing materials.
Medieval alchemists and apothecaries developed the muller because grinding substances by hand was inefficient—the flat head design allows gravity and pressure to do precise work, which is why the basic design hasn't changed in 800 years.
