Oil paints are pigment mixed with oil (traditionally linseed). Oil paint slowly oxidises into a hard form but remains moist and pliable for a long time. It can be applied in thick layers called impasto. In this work you can see how a light colour can then be applied over a darker one to cover it completely.

Using traditional oil glazes of dull green (terra verte) colour or a brownish pigment (burnt umber) as an underpainting to form the basic blocks of the composition. Then the mid and dark tones, and finally the lights were added.

Oil paints can be diluted to form thin transparent glazes. A build up of 5+ layers creates the subtle modelling of the facial forms. A thin white glaze over the hair and face creates the transparent veil.

Action painting introduced by the American abstract artists in 1950s added a new element of freedom and experimentation.

Watercolour paints are pigment mixed with a soluble gum arabic or other fixative. Light from the white paper is reflected back through the pigment. Watercolours are light sensitive so will fade in strong light. Watercolour paints are very convenient and transportable for outdoor studies. This work is a tight watercolour controlled within drawn forms.

This is a loose watercolour in which the wet layers of paint are overlapped and fuse together.

Gouache is an opaque watercolour paint with fluid characteristics and a somewhat dry powdery finish.

This relief work is painted canvas which breaks out of the normal single picture plane format. Releif works incorporate sculptural elements, crossing the traditional category of painting/sculpture.

Assemblage of found objects (rain coats, saw, onion bags, cut out drum lid). Like relief works, it has sculptural elements.
