Hello Richard,
The formula for the Sepia toner is from the "digitaltruth.com" site,
under technical data section where they list 130 darkroom formulas;
second down from the "massive dev chart". They have one formula for
Sepia toner..... that's the one I want to try.
I'm trying to find a replacement for the Kodak Sepia Toner that was
discontinued. Kodak now only sells Sepia toner II which I don't like.
Cheers,
Bogdan

Subject: [pure-silver] Sodium Hydroxide = Red Devil Lye
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 :)

According to a site dedicated to soap and candle making Red Devil lye
was removed from sale a few years ago. Sodium hydroxide is still
available from stores that sell supplies for this hobby. I could not
find Lion's Lye on the internet, perhaps its also off the market.
For most uses potassium hydroxide will do as well as the sodium salt
but is a bit more alkaline (higher pH).
What sepia toner formula do you have that requires hydroxide?
