Granulation Medium. Granulation Medium gives a mottled or granular appearance to colours which usually give a smooth wash, such as Winsor Red or Winsor Blue. By adding granulations Medium to colours that already granulate, such as Viridian or French Ultramarine, the effect is further enhanced. Granulation is popular wherever you want to add interest or dimension to otherwise flat areas.
Lifting Preparation. Lifting Preparation allows dry washes, including staining colours, to be more easily lifted from paper with a wet brush or sponge. It is an ideal preparation with which beginners can prime the paper allowing corrections to be made to their painting.
Blending Medium. This liquid is used to slow the drying rate of water colours allowing more time for blending. It is particularly useful in hot climates where artists would like their water colours to stay open and workable for a longer period of time.
Texture Medium. Texture medium contains fine particles and can be used to give the impression of depth and structure to water colour paintings. It is ideal for emphasising areas such as sandy beaches or the bark of a tree in figurative paintings. Used with multiple washes, Texture Medium catches different layers of colour and really gives a new dimension to water colour painting.
Iridescent Medium. This medium gives pearlescent or glitter effects to your water colours. It can be mixed directly with water colours or applied over a dried wash.
Gum Arabic. A pale coloured solution that increases the gloss and transparency of water colour. It can be thinned with water. Adding Gum Arabic to a water colour wash will have the following effects:
it will slow the drying time of your paint, giving you slightly longer to work on creating your image or working wet into wet
it increases transparency and gloss to give greater brilliance of colour, giving you luminous colours
it reduces the staining of pigments, making washes easier to lift
Ox Gall Liquid. A wetting agent used to improve flow when mixed directly with water colours. It can also be used on very hard sized papers to reduce surface tension.
