Mixing Slab

2 Review(s) | Add Your Review

Starting at: £24.00

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.

Gesso di Bologna

Starting at: £12.00

Gesso di Bologna is a bright white Calcium Sulphate, or gypsum, from Italy, which can be used as a substitute for whiting in the preparation of gesso. It is ground to a particularly fine powder, which makes it a suitable ground for gilding, as the small size of the particles allows for greater compression when burnishing. Learn More

Natural Beeswax

Starting at: £11.20

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.

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.

Whiting

Starting at: £4.00

Whiting is powdered Calcium Carbonate, which can be mixed with rabbit skin glue to create a chalk-based ground for oil, tempera, distemper or encaustic painting. Traditionally, whiting was an important ingredient when preparing painting surfaces in the north of Europe, as opposed to gypsum (Calcium Sulphate), which was widely used south of the Alps.

Powdered Rosin

Starting at: £13.90

Rosin is the powdered form of colophony, which is a by-product of the distillation of turpentine. Its primary application is to create tonal areas on metal plates as an aquatint resist. It is also an additive in etching grounds, where it gives a hard surface to the otherwise soft wax. Learn More

Parchment Clippings

Starting at: £9.90

Parchment Clippings, usually waste goatskin vellum, were utilised throughout the Middle Ages to make an animal hide glue. This continued to be commonly used as a sizing for canvas before rabbit skin glue came to prominence in the nineteenth century. Parchment glue is comparable to isinglass glue, as it also produces a very pale, almost transparent glue with a degree of flexibility. Our parchment clippings are a mixture of vellum scraps, and may include goatskin, calfskin and sheepskin. Cennino Cennini gives a recipe for gesso using parchment in his treatise about painting; please see below for our recipe. Learn More

Lemon Shellac

Starting at: £8.20

Shellac is a natural resin that is deposited by the female lac insect on the branches of trees in India and Thailand. It is soluble with alcohol, but not with mineral spirits or turpentine. It forms a tough yet flexible film, with many applications. It is suitable as a top coat for gilding when applied thinly, a sealant for porous surfaces, an isolating layer for tempera paintings, a base for pigmented inks, a protective layer for collograph plates, and a warm varnish for wooden floors and furniture. As it is prone to darkening with age, it is not recommended as a varnish for oils, and its solubility can reduce over time. There are various grades of shellac. When mixed with alcohol, it may initially form a cloudy mixture, due to traces of wax in the shellac, but this should become clear once it has dried. The highest grades of shellac are Clear Dewaxed Shellac, which has been de-coloured using the carbon filtering method, Lemon Shellac, and Orange Shellac, which are pale in colour. Button Shellac is less refined and therefore produces a reddish varnish. It was, in fact, widely used as a red dye before synthetic dyes became available. Learn More
