Cornelissen Glass Mullers

Starting at: £24.50

Cornelissen 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. The tall handle features an ergonomic top, to ease fatigue when grinding large amounts of pigment. 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. 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! Learn More

Colophony

Starting at: £7.30

Colophony is a by-product of the distillation of turpentine. It is soluble in most solvents, but considered an adulterant in varnishes and paints, as it forms a weak surface that is prone to darkening and cracking. It is, however, a key ingredient in wax-based etching grounds, imparting hardness, and can be used in powdered form (rosin) to make aquatints. Learn More

Microcrystalline Wax

Starting at: £8.50

Microcrystalline Wax is related to paraffin wax, and is used as a plasticiser in some recipes. It is characterised by the fineness of its crystals in contrast to the larger crystal of paraffin wax. It is generally more viscous, denser, tackier and more elastic than paraffin waxes, and has a higher melting point. Learn More

Carnauba Wax Grey

Starting at: £8.40

Carnauba Wax is the hardest wax commonly used in the production of artists' materials, with a melting point of 83-86°c. It is derived from a tree native to South America, and is available in a natural colour (grey), or a refined colour (pale yellow). Small amounts of carnauba wax are commonly used in both oil painting mediums and encaustic painting, usually in conjunction with beeswax to add toughness, durability and sheen to the paint film. It creates an inflexible surface, so works best on rigid supports such as gesso panels, and it should be noted that it will raise the melting point of encaustic mixtures. It can produce a glossy finish; as such it is used in waxes and polishes for shoes, cars, musical instruments, furniture, and wooden floors, especially when mixed with beeswax and turpentine.

Genuine Malachite Pigment

Starting at: £14.90

Malachite is a naturally occurring copper carbonate, closely related to Azurite. It has a weak tinting strength, is quite opaque, and works best in aqueous media. Larger sizes available on request. Learn More

Gypsum

Starting at: £5.70

Gypsum is powdered Calcium Sulphate, a traditional ingredient in gesso grounds used in southern Europe. One of the advantages of preparing your painting surface with gypsum is that it allows for a particularly even absorption of the paint film. It can also be added to acrylic primers to increase absorbency or add tooth to a surface. 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

Stil de Grain

Starting at: £12.20

NY13:75640 Stil de Grain is a natural yellow pigment derived from unripe buckthorn berries, which were also once used to produce sap green pigment before the introduction of synthetic alternatives. Stil de Grain may also be known as brown lake, yellow lake, Persian lake, buckthorn lake, Dutch pink, yellow carmine and Italian pink. It has a weak tinting strength, and is very transparent, especially in oil. When mixed with oil, the pigment becomes saturated, darkening considerably in colour and drying very slowly, whereas in a water-based paint it is appears as a warm yellow. It is very fugitive to light, and compatible with all media, except lime. Larger quantities are available by request. Learn More

Ivory Black Genuine Pigment

Starting at: £38.00

PBk9

Genuine Ivory Black is produced by burning reclaimed ivory, such as piano keys.

Isinglass

Starting at: £30.10

Isinglass is derived from the dried swim bladders of fish, with Salianski Isinglass being the highest grade available. In the Russian Icon tradition, it commonly provided the glue component in gesso recipes, and was sometimes mixed with pigment to make tempera paints, due to its high binding strength. It can be used to make a pale, clear glue, which is less prone to darkening than other animal glues, and which is particularly flexible, making it a useful material for repairing textiles.

Alumina Hydrate Light

Starting at: £8.30

Alumina Hydrate is an inert pigment with highly absorbent properties, which can be ground into oil paint as an almost colourless extender. It is often used as an additive in commercial oil paints, particularly in conjunction with transparent or lake pigments, as it provides stability and a homogenous consistency without effecting colour or gloss, although it may effect the pigment strength. When combined with linseed oil, it produces an almost transparent painting medium for extending oil colours. Sometimes referred to as Lake Base. Learn More

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

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

Paraffin Wax

Starting at: £6.60

Paraffin Wax is a by-product of the petro-chemical industry. It has a low melting point of 50-60°c and a brittle texture, making it unsuitable for encaustic painting or as an additive to oil paints, but it can be used to impart softness to lithographic crayons. As a petroleum product, it is more inert than animal or vegetable waxes, and is therefore not saponified (turned into soap) by alkali substances. Learn More
