The Silverpoint Composite Underdrawing
June 6, 2022
I’ve finally completed the sixty-four silverpoint underdrawings in preparation for a painting – as yet to come. The panels were developed individually – and were based on black and white sectionals of a photograph. The MDF panels were all prepared with an acrylic ground tinted with a mixture of dry pigments to simulate terre verte, because the actual dry pigment, terre verte, reacts negatively with acrylic rendering it unworkable – in that particular medium. Of course, I could have used a tint of white for my ground colour but I already knew how much I enjoyed working from a toned ground. The silver lines could be used to subtly create linear form while then the addition of an acrylic wash of white highlights could help it to “pop”! In addition, I coated each tinted gesso panel with a transparent covering of Golden’s Pastel Ground, in order to create a fuzzy toothiness.

Assembling the panels on the backing board.
Now, since this level has been completed I’ve encountered two main problems-to-solve: 1) in the areas of darkest value which required a lot of cross-hatching of the silver particles, the image possesses a reflective sheen. Is it possible to minimise this reflectivity?; 2) even though silverpoint has the reputation for leaving an indelible mark, I have found that that is not really the case. Both water and a kneaded eraser can, in fact, diminish the image. So, before I proceed any further, I want to “fix” the drawing. What material should I use to do this? A traditional pastel fixative or a matte acrylic varnish? In addition, would this proposed fixative help to diminish my sheen problem?
After some research and consultation with the expert folks at the University of Delaware’s MITRA forum, I have decided to spray an adequate covering of Lascaux (an acrylic medium containing B-72) Fixative over the whole assemblage before proceeding any further. Because I anticipate further layers of abstraction, using a Liquitex transparent titanium white spray over the image my silver sheen issue may take care of itself?
Fast forward to a few months later. The fixative, fixed, and the matte spray pain reduced the sheen.
What remained was for me to throw some paint at it.
