How should Granulation Medium be used?
Granulation Medium will cause colours which usually give smooth washes to granulate to a greater or lesser degree depending on the pigment. Generally the modern pigments, prefixed by ‘Permanent’ or ‘Winsor’ will be most affected by the medium. For maximum effect, wet the desired area of paper with the medium and then make a washes using the medium instead of water. Apply it and leave to dry. All granulated washes dry flatter, if this occurs, as the wash dries keep disturbing it with a brush. This will prevent the wash just flowing into itself and levelling out. Granulation is also increased by the roughness of the paper and by the absorbency. As with all techniques any new method needs practice and as with all water colour washes it can never be guaranteed to get exactly the same results every time.
