A glass slab with wooden cradle for the grinding of pigments.

The friction created between the sand-blasted surfaces of the glass slab and muller facilitates the thorough mixing of pigment and medium, creating a consistent and strong paint body. This slab can be used to manufacture many types of paint including watercolours, egg tempera and oils.

Mulling is of particular importance when making oil paint; simply mixing pigment and oil together using a palette knife will result in an unstable substance with poor plasticity, which contains a large amount of excess oil and unevenly distributed pigment particles. Thorough mulling in a figure-of-eight motion will enable the pigment to be fully combined into the binder, strengthening the resultant paint film.

PLEASE NOTE: The separate glass slabs are in stock but it is a call to order item due to the fact that we cannot guarantee its safe delivery, however well we package it. Please ring us to discuss your delivery options. In combination with the glass frame, delivery is more secure but we still cannot guarantee a delivery without breakage.

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.

Burnt Umber is a natural earth pigment from Italy, composed of iron oxide, manganese, and aluminium silicate. It is a form of Raw Umber that a has undergone a process of calcination, becoming warmer, more transparent and easier to disperse. It has a good tinting strength, and is very lightfast, quick-drying, and stable in all media. In oils it forms a hard, fairly flexible paint film, though it may be difficult to use in acrylic mediums.

Ivory Black is a natural pigment of impure carbon, derived from charred animal bones. It is semi-transparent, very lightfast, and offers good tinting strength. It is a particularly slow-drying pigment, which forms a soft, rather brittle paint film in oil.

Compared to other blacks, such as Vine Black, Ivory Black possesses warmer, brownish undertones. It should not be used at full-strength in an underpainting, as subsequent layers are likely to crack. Otherwise, it is a very useful all-purpose black for many types of paint, excluding mortar, fresco or cement.

Beeswax is derived from melted honeycomb, and is available in two grades. Bleached Beeswax Pellets are white, having been bleached by the sun, and are an appropriate choice for using with pale colours, although they may revert to yellow over time. Natural Beeswax Pellets are yellow in colour, and offer a more flexible structure with a higher resin content. Beeswax has a melting point of 63-66°c, and may turn brown if over-heated. It is the most widely used wax in artists' materials, having a wide range of applications. Please see below for more details.

Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

Zinc White, or Zinc Oxide, is an artificial mineral pigment that was first produced in France in the late 18th century. Its use in commercial watercolours as Chinese White pre-dates its inclusion in oil painting. It is a semi-opaque, lightfast pigment, which dries very slowly in oil. Of all white pigments, it produces the most brittle paint film, so is not recommended in large quantities for impasto techniques. However, it is a good addition to a palette which requires a less overwhelming white than Titanium White.
