Glass pestle for grinding pigments, diam. 5cm, extra heavy

Glass mullers are handmade. The bulbous handle is specially formed to provide a comfortable grip. The bottom of the glass muller is flat and sandblasted to provide an excellent grinding surface. Use the glass muller on the grinding plate to grind and disperse pigments and other materials into paint medium. Both surfaces of the muller and the grinding slab should be retextured periodically after use. To disperse pigments in paint medium, place a small quantity of powdered pigment and binder on the grinding surface. Begin grinding the paste in circular motion until the paste has a smooth consistency.
