glycin order/storage advice
I too am sensitive to shipping charges. Order from the Formulary - I understand that they make Glycin up regularly. Product that I have bought from them arrived white in colour. Glycin oxidizes easily in a dry state quite readily, and it is easy to buy a grey or tan ( ie less active) powder from other vendors.
Once you get the powder, store it in the freezer in a moisture resistant container - I use Bud's standard plastic ones with some black electrical tape wrapped around the outside of the cap over the threads. Glycin stays white a long time when it is kept frozen. Mine is heading into a second year, I think, and it looks as gooda as new. Just scrape out what you need, direct from the frozen state to the scale pan/paper, and then into the solution.
Glycin keeps a long time once in solution. I run it in a batch of Harveys 777 that I work on feeding a film to at least once every three weeks, with recommended replenishment. The same batch has been good to me for periods of over a year. Ansco 130 paper developer, another formula that I buy glycin for gives nice warm toned action when I am printing fibre and want a warm toned image on a compatible type of paper, and it sits happily on the shelf over the sink until it is called on.
