Cornelissen Professional Glass Mullers are handmade and have an ergonomic handle to ease fatigue when grinding large amounts of pigment. The base of the muller is ground flat and has been sandblasted to create a fine tooth to facilitate the grinding of pigment. Mullers are used to grind pigment to a floury consistency for mixing in a suitable oil or medium. In order for a pigment to color the medium richly and evenly, it must be finely ground.
