In the near future I will eventually be hiring darkroom space from an artists collective that isn't in walking distance from where I live, and they require that you bring your own paper and chemistry for printing. I was wondering what the best way would be to transport my chemistry? As it is I have most of my chemistry in accordion bottles, but I'm a little worried about how they would fare being shoved in and out of a backpack. As I don't have a driver's license I will be travelling by subway, and I would be going there after work, so the chemistry would sit in my backpack throughout the workday. So what should I be thinking of before chucking my bottles in my backpack and trodding off?
