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.

The perfect introduction to working with pigment, this selection of thirty pigments provides a wide range of colours for the production of paint. Each colour is supplied in a 15ml plastic jar, and the set includes both natural and synthetic colours. Recipes can be found on our homepage, with instructions for making different paints, including watercolour, egg tempera and oil paint. Learn More

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.
