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.

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."
