This use of silver gelatine paper as POP is a bit unpredictable. I tend to
use it as a cabaret act for workshops etc. The most suucessful ones are on
pages 7& 8 of Spirits of Salts. Every paper seems to have its own
characteristic.Joe Portale gave a clear account of POP and DOP. Exposure is
quite long- as least as long as cyanotype or longer. The amber coloured
prints in the book are on commercially produced POP ( rersin coated)by
Kentmere. I bought the last few packets some years ago. As far as we know
its original purpose was measuring airborne radiation.I tend to work with
paper and glass plates well past expiry date.-- sometimes as much as 30
years old. There is a commercial POP (fibre based ) known here as
Centennial. I think it is made in the US. Alternatively make your own!
Good luck with the class.
