Charcoal and silver leaf
I'm a charcoal portrait artist working on heavy tinted paper. I'm interested in experimenting with gilding silver leaf accents on my charcoal drawings.
I know that gold leaf will not tarnish and therefore requires no varnish. But I'm interested in silver leaf which will need to be varnished. I'm unsure of how this will affect my charcoal drawings.
Generally I frame my drawings without any fixative, but I have occasionally used a spray fixative. I doubt that spray fixative will be sufficient for the silver, but maybe I'm wrong. And I don't know how a brush applied varnish will affect the charcoal.
I'm going to do some experimenting on a small scale, but thought I'd check to see if any of you have experience with this.
