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 -

Gum Arabic
Starting at: £6.30
Gum Arabic is a resoluble binding agent, commonly used in the preparation of watercolours, but also useful as an adhesive, a size, and in the production of soft pastels. It is a natural product, harvested from the Acacia tree between October and May. The highest grade of Gum Arabic comes from the Kordofan region of Sudan. It is exceptionally pale and pure and therefore particularly suited to watercolour painting. Please see the Formulas & Recipes section on our homepage for a recipe to make your own watercolour paints using Gum Arabic (currently under construction). Learn More -
Gum Benzoin
Starting at: £14.70
Gum Benzoin is used as a fixative, slowing the dispersion of essential oils and other materials into the air. Is occasionally called for in some old varnish recipes where it was employed primarily for its odour. Learn More -
Gum Damar
Starting at: £10.00
Damar is a pale, almost colourless tree resin, which is soluble in turpentine, but not in alcohol or mineral spirits. It can be used as a varnish or as a glossy painting medium in conjunction with vegetable oils, and is generally preferable to other resin-based varnishes, such as mastic varnish, as it retains its colourless appearance for a longer period of time. In encaustic painting, the inclusion of damar resin imparts toughness and gloss to the paint surface. Learn More -
Gum Mastic
Starting at: £20.30
Call to Order
Gum Mastic is a tree resin, which dissolves into a clear varnish with alcohol or turpentine, but not with mineral spirits. Mastic varnishes are more prone to blooming and darkening with age than damar-based varnishes, and painting mediums that contain gum mastic can deteriorate in unpredictable ways. For this reason, it is primarily used in restoration, rather than in the production of artwork. Learn More -
Gum Sandarac
Starting at: £8.60
Gum Sandarac, derived from a coniferous tree, is available in powdered or lump form. It can be dissolved in alcohol to create a varnish that is suitable as an isolating layer in oil painting and as a traditional top coat for egg tempera. It forms a brittle layer, so is only suitable for use on a rigid support. Another application is as a surface preparation for calligraphy; the ground gum can be dusted across a piece of prepared vellum or paper to create a resist, which shrinks ink strokes slightly, making them appear finer, with crisp edges.

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 -
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 -
