Roberson Glass Mullers

4 Review(s) | Add Your Review

Starting at: £25.00

Roberson Glass Mullers are handmade using high quality-glass.

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.

Lapis Lazuli Pigment

Call to Order

PB29

Lapis Lazuli is a natural mineral pigment, mined in Afghanistan and South America. For many centuries it was the most reliable blue pigment available, and became particularly significant during the Medieval and Renaissance periods, when its inclusion in a work of art denoted the wealth and status of the patron, or the holiness of a painting's subject. In commercial paint production it has largely been replaced by the more affordable Ultramarine Blue, although it still has a place on modern palettes due to its unique soft violet tone. It is a transparent pigment, with a low tinting strength.

[We will have stock of Lapis Lazuli in September. If you would like to be called when it is available, please use our contact form to let us know.]
