Gord,

I checked Post-Factory & found under "Ingredients/ materials" category
"Everythinbg Else" Gelatin: USB Corp in Cleveland, O. Porcine gelatin in
all blooms, soft to hard. 216/765-5000, or fax 216/464-5075.

  But I think maybe there should be a better way to list... if I hadn't
known it was there somewhere, I probably wouldn't have found it. Maybe
just alphabetical? (I need a computer program.) Anyway, I've bought their
hard gelatin by the pound... less than $10, if they're interested in
shipping white crystals internationally. ;-)

cheers,

Judy
