Hi there. This question arose only because I am on the East coast,
and nobody here carries Pumice powder of the type or coarseness that
we use at the Art College. Normally I buy pumice powder from
Gesswein Canada in Toronto, but at 4.50 a pound (plus shipping) this
gets a little pricey. Can anyone suggest a supplier, either in
Canada or the Eastern States, that I can purchase pumice from in,
say, 20 lb. drums or boxes?
Thanks for any help,
