Sodium Hypo = Sodium Thiosulfate

Chemicals can be purchased from many companies. I use the Photographers Formulary in Montana, and APUG sponsor.

Use Battery Acid. It is 37% Sulfuric Acid and can be purchased at any auto store. Use gloves, goggles and an apron when handling the stuff and when handling and using the bleach.

You can do the final development in total room light, but I would use 1 minute room light exposure to each side if you go back into the darkroom.

AAron, are you sure you want to mess with the chemicals? You can buy a kit for this!
