Methods and materials for pastel paintings:
A variety of water-colour papers, pastel papers and grounds are
employed. Sanders Waterford 90lb NOT surface is frequently
used, the white surface being useful for transparent effects.
The reverse of Canson pastel paper is a favourite for opaque
working in pastel. Both Sanders Waterford and Canson permit
easy blending of the pastel - a key element of the work featured
here.
Rougher surfaces stimulate broad and expressive treatment. Of the
'sanded' type boards, Art Spectrum Colourfix and Sennelier
pastel papers are used. The fine glasspaper type texture of
these grounds promotes direct treatment and inhibits blending.
Surfaces can be very lightly sanded to modify the ‘tooth’ when
required.
Unison pastels, supplemented occasionally by other makes, are used
most frequently. Unison offer a good range of lightfast
colours, are intermediate in softness and withstand reasonable
pressure without crumbling. The fine pigment structure
facilitates smooth blending.
I favour a white or very pale ground which permits the use of
semi-transparent techniques more usually associated with
watercolour. Allowances have to be made for the effect of the
white on tonal values. If preferred the white base can be
tinted with a base layer of pastel, water colour, gouache,
diluted acrylic paint or ink, to suit the working method.
Working on a darker, or coloured ground can be equally
stimulating and has been described as ‘sculpting with light’.
Some artists prefer to start on a mid-tone ground working
outwards towards the lighter and darker ends of the tonal
spectrum.
My work is rarely sprayed with fixative at any stage. Fixative
renders lighter surface colours transparent and highlights are
lost. When applied thickly, colours are less affected by
fixative. Some artists fix their work in the early stages while
continuing to build up colour. Unfixed work requires careful
management prior to framing, but once behind glass is no more or
less vulnerable than any other medium.
A key advantage of pastel over almost all other types of
painting medium is its unchanging state throughout the working
process. A pastel painting can be reworked with ease after any
period of time has elapsed.
