BackInService, Sodium Thiosulfate (ST) that I use looks like very small pieces of broken safety glass or little crystals that are roughly half the size of a pea. It has a very mild taste that is slightly salty, but I only use a few crystals at a time mixed in a glass of water so the taste is not strong. I don't know about storage because I only make it as needed. You might research Ted's remedies as he used and recommended ST.
