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

Finest quality gouache paints, available in 48 shades, all of which are fully inter-mixable with the HORADAM® WATERCOLOUR range. Made following a traditional gum arabic recipe, they are naturally opaque, without the addition of white. They provide a luminous, velvet-matte finish, drying to a slightly lighter shade than when wet. 

Schmincke recommends the following:

"The application possibilities of HORADAM® GOUACHE are extremely versatile. Although it can be heavily diluted, gouache is mainly intended to provide opaque application of colour. Opaque, in this case, means that it is not impasto, because impasto application tends to produce cracking, unless the percentage of binder is increased by adding gum arabic (50302). While watercolour painting work goes from light to dark (the white paper is the light), in gouache painting, any process can be used. While “back painting” of lights is limited in watercolour painting, when working in gouache (and other opaque colours), light values and lights can be added later using colours."

Prussian Blue is a synthetic organic pigment that was discovered by the paint maker Diesbach, apparently by accident, in Germany in the early eighteenth century. For many years, it was used not only as a colour in its own right, but also as a component of the original Hooker's Green. The other ingredient, gamboge, is highly fugitive, which is why many watercolours painted with Hooker's green have taken on a bluish tone with with age.  

It is a very transparent and heavily staining colour. It dries quite quickly in oil, and can therefore wrinkly if applied too quickly. It is suitable for use in oils, watercolour, and egg tempera. However, it shouldn't be used in conjunction with alkali substances, such as Lead White or Calcium Carbonate as it can turn brown, so it isn't suitable for fresco. For the same reason, it isn't used with acrylic resin binders due to their alkaline nature, so most paint manufacturers will replace Prussian Blue with a mixture of Phthalo Blue and black in their acrylic ranges. It requires a wetting agent to fully disperse into a binder.

Cobalt Blue is an artificial mineral pigment, produced by the calcination of cobalt oxide and aluminium oxide. It has been widely used since the early 1800s, following its discovery by the French chemist Thenard at the beginning of the century. The name Cobalt has its roots in the German word Kobold, meaning imp or evil spirit. German miners named it to in the late-Middle Ages, as the presence of cobalt ore in the mines made the extraction of silver more difficult. They were possibly also aware of the toxic properties of the mineral that was frustrating their efforts.

Cobalt remains a very popular colour today, and is present in most ranges of paints, being a semi-transparent pigment that is stable in all media. As a watercolour, all cobalt pigments tend to granulate. As an oil paint, it requires less oil content than most other pigments, and dries quite quickly. Like Cerulean Blue, some artists may choose to bind it with poppy oil, to avoid any possible colour changes brought about by the yellowish cast of linseed oil and the pigment's weak tinting strength.

Casein is a protein derived from dried milk, which has been used in painting since ancient times. It can be combined with Ammonium Carbonate to form an emulsion, which acts as a durable, non-resoluble binder for pigments, producing a matte, fast-drying paint, similar in appearance to egg tempera. We use casein as a binder for our L. Cornelissen & Son Pigment Colour Charts, as it is a medium that clearly showcases the characteristics and behaviour of each pigment in its pure form. Casein paints can be applied in thin layers to watercolour paper, but would require a more rigid support, such as a gesso panel, to be applied thickly, as the comparative inflexibility of the paint layer means that it can be prone to cracking. Subsequent layers of paint should be more diluted to aid adhesion, and impasto effects are not recommended. It is possible to varnish casein paintings using an acrylic or damar varnish to obtain a glossy surface if desired, although this is not a necessary step. Casein can also be used as an ingredient in gesso, and is a suitable binder for fresco secco techniques.

Some pigments may require a wetting agent in order to fully disperse within the binder, in which case alcohol may be used.

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.
