1. Is POP the same thing as salted paper in The Keepers of Light?
2. Do you think POP is relatively easier or harder than gum print?
3. The above formula is called "warm-tone POP." Is there a cold tone formula?
4. Where can I find more information/instructions on POP?
5. Is there any danger with the above chemical. I don't mean the usual legal
stuff where everything is dangerous, but is there any known danger like
extremely poisonous or when heated or mixed with such as such will release
toxic or fatal fume?
Thanks a lot in advance!
