Re: Diane Townsend dry grounds
No, I haven't used it yet, but your post intrigued me. I can recall reading that many pastellists in the past, including Rosalba Carriera, would rub their papers down with a pumice stone prior to drawing & painting with pastels. According to Diane Townsend's website:
"The dry ground is a pumice based chunk of material made to be applied to paper and rubbed in with your hand. The purpose of such a ground is to give a bit of "tooth" to a surface which will grab the pastel and make it smooth for layering."
So, from what I can tell, Diane is providing a tool that allows us to revive a historical practice. Casey Klahn seems to be using the dry ground in his work with charcoal and pastel. I will order some this weekend and report back with results. For those working on paper, it sounds like another nice tool to have available.
