Q: 10. Whats the shelf life of the dry powder? Can i make accurately weighted small batches of the powder and make lets say 1/3s of a gallon each time instead of making the whole gallon in one go?

A: I don't recall if it has an expiration date on it or not, but I've opened packages that were a couple years old and they worked perfectly fine. However mixing small batches probably isn't a good idea. I imagine you'd get pretty inconsistent results. I'd recommend just mixing up a gallon and keeping it in an air tight container. I've kept it many months that way with no adverse effects. Even if some goes bad, that's better than ruining film with inconsistent small batches. An alternative, if you can ship liquids to your location, would be to look into rodinal developer.
