Mullers act as flat-bottomed pestles, which are used to grind pigment into a binding medium, suspending it evenly to create a uniform covering of binder around each pigment particle. Using a muller and slab, rather than simply mixing pigment and binder together, will create a more homogenised and stable paint. Roberson Glass Mullers are handmade using superior boro silicate laboratory glass, which is 40% harder, more heat resistant, and offers better clarity than soda-lime glass. The base of each muller is ground perfectly flat, and sand-blasted to create a fine tooth to facilitate the grinding of pigments.Use in conjunction with a Cornelissen Glass Slab to make paint efficiently. The sand-blasted texture of the muller and plate helps to push and distribute the pigment throughout the binder quickly. This will mean less grinding, and more painting! NOTE: Sizes may vary slightly as these are handmade products. Learn More
