Conrad:(posted 8176 days ago)Look behind any good resaurant and see how many dark green empty wine bottles there are- absoutely nothing wrong with them, specially if you empty them yourself.
I often scour the recycle boxes on the streets (in Toronto) for glass and plastic bottles for photo stuff. The best jugs I found are the ones used for absorbent cat litter: -very wide mouths and solid. Also the risk of contamination from clean Kitty litter is very low.
I have never had any problems with plastic, even with developers for many months.
PET (Poly Ethylene Pterthalate)is used for food because it is quite good at keeping oxygen out, is resisitant to cleaning solutions and can bounce. There is no reason why a used PET Coke bottle can not be used for photo stuff. Glass was the best at one time, but, as they say, sort of: "Better things for better photography through chemistry"
