Pastels- Sarah Brock
To produce strong colour using pastel one must use a good ground
with ‘great tooth’. Sarah had us experimenting with different gesso on canvas
glued onto board. The gesso was mixed with ‘grit’, pumice, oatmeal . We even
used hessian and calico instead of canvas. This of course dictated a bit the
type of image that would be better on the different rough surfaces, Images with
fine details would be hard to put onto the hessian however you could get quite
good detail on 1200 grit sandpaper.
The eye is instinctively attracted to sharp
edges and strong contrast. I had fun covering the boards we made in the first
few days, rabbits on the hessian, oranges on the grit covered canvas, a nude on
pastel paper and faces and lions on sandpaper.
