Re: dichromate stain and chemistry question



Well, I have to be honest with both you and Judy, Loris,
Before that Science Supply House in CA went out of business, long before, I ordered a liter of sulfuric, hydrochloric, and phosphoric acid, and actually got it shipped to me by mail! Nowadays I can't even get Rodinal from B and H, for instance.
This year I was thinking that I might get rid of them because I really don't use them. Now I'm glad I didn't.
But my real reason for not recommending them is that legally nowadays you really have to watch what you teach and suggest for people to use because if they are cavalier with these acids it's a lot more dangerous than being cavalier with developer or something.
However, as of late I have been printing some gum tests without pigment, and so when I get back to my dimroom I am going to test this formula...for personal interest...
