The link I had to digital truth has gone bad, so I googled around and got this, (from here):
Water 750ml 125F
Sodium sulfite 100g
Borax (20 Mule Team is ok) 2g
Water to make 1.0L
Mind you, the first respondee to that thread, ffs, what's his problem? "It isn't really wise to do this from powder." And, "use what you will and trash the rest." There was a cheeky bastard in DIY B&W, too. What makes people come out with this drivel?
