  2. Ammonium Carbonate

    Ammonium Carbonate

    Starting at: £9.70

    Ammonium Carbonate is a highly Alkaline substance that reacts with the lactic acid present in casein to form a robust binder for tempera paints. It should only be used in a well-ventilated area, please see below for the Material Safety Data Sheet. Learn More
  3. Paraffin Wax

    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
  4. Microcrystalline Wax

    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
  5. Orange Shellac

    Orange Shellac

    Starting at: £8.00

    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
  6. Lemon Shellac

  14. Colophony

    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
  15. Gum Tragacanth

    Gum Tragacanth

  16. Gum Sandarac

    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. Learn More
  17. Gum Mastic

    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
  18. Gum Damar

    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
  19. Gum Copal Manila

    Gum Copal Manila

    Starting at: £6.00

    Gum Copal Manila is derived from the resin of a coniferous tree native to the Philippines. It is not to be confused with other copals, which are the product of fossilised plant materials. It can be dissolved in alcohol to make a spirit varnish, to be used as a substitute for shellac, or as a fixative for pastel and charcoal drawings. Please note, that when used as a fixative it may darken the colour of the image. Learn More
  20. Gum Benzoin

    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
  21. Gum Arabic

    Gum Arabic

    Starting at: £4.25

    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, while Nigerian Gum Arabic (while stocks last) is better suited to stone lithography and other printmaking techniques. 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

    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.
