I enjoy using sanded pastel paper but the paper itself is super expensive so I make my own pastel ground/primer. This is typically apply it to the surface of watercolor paper, mat board, or illustration board to make an abrasive surface for better pastel use. This is a lot less expensive then buying the paper or commercial ground.
I'm currently making the pastel ground/primer using a mixture of gesso, pumice powder, and water. However, I'd like something a little less abrasive. I've gotten a bag of marble dust to try but it just comes out like really thick gesso.
Is there a good recipe to make a pastel ground using marble dust?
For reference, here are a couple of commercial pastel grounds/primers available: - https://www.dickblick.com/products/golden-pastel-ground/ - https://www.dickblick.com/products/art-spectrum-pastel-and-multimedia-primer/
