GLASS GRINDERS - designed for grinding dry pigment mixed with a binder on a glass surface to create paint or enrich it. Grinding further breaks down the pigment and ensures it blends well with the binder. The grinding dish is made entirely of crystal glass. It is available in two base diameters: 79 mm and 114 mm, with a frosted base.
