Genuine Indigo is a natural vegetable pigment derived from the Indigofera Tinctoria plant, which was first imported into Europe from India in the seventeenth century. It replaced woad, which had been grown natively in Europe for its blue dye. The leaves are soaked in water to ferment; upon drying, an oxidised residue forms on the dry leaves, which is removed, washed, boiled in water, and then dried to form cakes of pigment or dye.

Indigo is very transparent, with a good tinting strength. It requires a wetting agent to disperse, and in oil it dries very slowly. It is fugitive to light; this drawback means that it is no longer commonly available in commercial paints. It fell out of general use at the beginning of the seventeenth century, largely replaced by Prussian Blue, and synthetic Indigo was patented in the 1890s. However, it provides a subtle shade of blue that is still desirable in works that are going to be protected from light.

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.

Kölner Instacoll is a two-part system, consisting of a base coat and activator, that can be used on nearly all suitably prepared substrates to create weather-resistant, high gloss interior and exterior gilded surfaces. The Instacoll Tool is a double-ended tool with shaped tips made of elastic rubber, designed for pressing gold and silver transfer leaf into indentations when gilding uneven surfaces. The Instacoll Chiffonnette is an extra soft, lint-free cloth, used for polishing and burnishing surfaces gilded with Instacoll. *PLEASE NOTE - COLOURS OF THESE PRODUCTS MAY VARY SLIGHTLY FROM PRODUCTS PICTURED* Learn More

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.

** While stocks last ** Blue Verditer, sometimes referred to as Bremen Blue, is a synthetic form of Azurite, or copper-calcium carbonate. It has a weak tinting strength and is sligtly transparent. It works best in water-based binders, as the acidity of linseed oil can cause discolouration.

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

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.

Galkyd Light is produced by Gamblin. They write:

"Galkyd Lite thins oil colours and increases transparency and gloss. When used in moderation with oil colours, Galkyd Lite will retain brushstrokes. Galkyd Lite is more fluid and less glossy compared to Galkyd. Thin layers will be touch-dry in 24 to 30 hours."

Smalt is a kind of cobalt blue glass or frit, and its use as a pigment dates from the 1600s in the glass-making regions of Saxony. We offer two shades, light and dark, which are determined by the particle size of the pigment; the more finely ground the powder, the paler the colour. Before the introduction of Ultramarine Blue, Smalt was available in a wide variety of grades. It is a very transparent pigment, which is easily overwhelmed in mixtures due to its weak tinting strength. It works best in water based media. When ground in oil, it can become almost invisible in dried oil-paint films because its refractive index is so close to that of linseed oil.

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

Genuine Ivory Black is produced by burning reclaimed ivory, such as piano keys. These are antique, mainly Victorian pieces, using ivory with started out as hippo or walrus teeth, and offers a higher carbon content and greater tinting strength than modern-day equivalents, which are usually derived from animal bones. It is a particularly slow-drying pigment.
