Well, if you've iodine and potassium iodide for making
that tincture I thought you might also have some
sodium sulfide.

In the usual bleach and redevelop process sodium
sulfide is used. Why bother to buy a brand name
SODIUM SULFIDE. That would be the same as
buying a brand name SODIUM METABORATE.

Brand name SODIUM TETRABORAT and SODIUM
CARBONATE and a few others is another mater.

BTW, I've noticed no odor with weak
solutions of sodium sulfide. Dan
