PUMICE
Pumice is a light colored volcanic rock used as an abrasive. It can be used to make your own pastel ground by mixing with gesso or other priming material. We carry the 4F very fine grade and in a 1 lb. jar. Wearing a dust mask is recommended when working with pumice powder.

Looks like it will do the job, making my own pastel grounds. Will know how well in a few weeks.
