Hi All,
This is a bit off the wall but I'm taking a chance that somebody
in our august and diversified group might be of help.
The only large supplier of photograde chemicals in Canada is a 15
minute ride from my place. In my order I needed Sodium Hydroxide
to make a particular solution of Sepia Toner. She informed this
afternoon that she doesn't carry it anymore because of the very
low demand. I was the first person in year who asked for it. So
I substituted Potassium Hydroxide at the ratio of 10:14 by weight.
Now the question? Anchell in the "Darkroom Cookbook" suggests
that a substitute for Sodium Hydroxide is RED DEVIL Lye. This is
an American label (I'm Canadian) and several people I have spoken
to have never heard of it. My wife told me that her mother used
to use LIONS Lye to flush out the drains but I don't know if it is
a substitute for RED DEVIL; I don't know if it can even be bought
anymore.
Would anybody, perchance, on the off chance, trivial pursuit
question, ...... have an idea of a Canadian substitute for RED
DEVIL Lye to replace the Sodium Hydroxide?????
Pleeeeeese.......
It's nice to be able to lug home a 5 Kg container of Sodium
Thiosulphate
Cheers :)
