big snippy...

Richard mentioned...

Groceries used to carry Red Devil Lye, perfectly pure sodium hydroxide, and
also 20 Mule-Team Borax, also pure enough for photographic uses. Both are
useful in themselves but can be combined in solution to form "Kodalk" AKA
sodium metaborate, pentahydrate (although Kodak called it octahydrate).

You may not remember Richard, but i went out and bought 100 lbs of both
because Kodalk is so expensive. I have been making my own for some time and
it costs me 1/8th of what Kodalk would cost.
