Other than Photographer's Formulary, does anyone have a source for Baryta coated paper that does not have any sort of emulsion coated on it? Inkjet papers will not work. I'm playing with Collodion P.O.P. and it requires Baryta paper. I ordered a small amount from Photo. Formulary, but I'm worried that one day it may sell out and be unavailable there.

Any help would be appreciated!

Thanks!
