Local exhibition time approaches, a couple of months' time, so I need to over-view my products from the past six to twelve months and decide what to frame up.
Today's pastel is a very simple one; just a pear on a plate. I had been tempted to add a spoon, or even a lump of cream to the plate, but somehow couldn't bring myself to do it. The surface is a sheet of watercolour paper that has been painted over with white gesso. I started the general drawing of the pear and plate with a Conte stick; once the outlines were in place, I began to lightly fill in colour on the pear using a few Rembrandt pastels. For the plate I put down a few blue-greys, and marked in a darker grey for the pear's shadow.
At this time I have been experimenting with using acrylic polymer medium as a fixative and also as a fluid for "painting" the pastel. Bill Creevy's 1990's book "The Pastel Painting Book" contains a number of examples where he has used acrylic medium as a fixative; and Dawn Emerson also talks about the use of acrylic matt medium as a "painting" fluid in her "Pastel Innovations" book.
The thing to keep in mind is that the medium will dissolve the pastel and muss up any patterning or fine detail that you may have laid in; so it's best not to do too much of that. Bill Creevy's aim was to build up pastel layers; you can add dry pastel on top of the acrylic-medium treated work with little problem, when it is dry.
In my case, I was just playing with the technique to see what would happen. After initial pastel layers were put down, I got a soft-ish brush and painted acrylic medium over the pear and over the plate. Now....at the moment I only have the gloss medium. It does work fine, but tends to leave some shiny areas. I will be getting myself some matt medium in due course. When dry, I continued pastelling. I coloured in the background around the plate; initially it was a red-brown with some deep-blue streaks, but I didn't like it and tried to add another colour on top to change it. As a result I filled the tooth of the surface.
So....after brushing a lot off, I painted over it with acrylic medium and left it to dry. Now, the whole picture had been fixed. A thought of further experimentation seized me and I picked up my pot of clear gesso, covering the whole painting with it and creating more tooth.
The rest of the painting was completed by adding the pear's markings with soft Unison pastels; putting in the plate's gold rim and indicating subtle shadowing on what was actually quite a flat plate; and finally going for a complementary deep blue background. In the end I am glad I added more tooth to the surface; and I also proved to myself that it could be done partway through a work.
