Im trying to try out Gainers modified Rodinal formula with Sodium Ascorbate and Borax. I got some borax from a potters supplies but im having a heck of a time dissolving the damned stuff. Can never seem to disolve all of it. Ive tried boiling water, and warm water both before and after adding sodium ascorbate and rodinal, but just seems to dissolve SLOWLY - like hours of stirring it would seem... Would it be best to get a mortar and pessle and pulverise the crap out of it first? or is there some trick? Also, can i make up a known concentrate of borax and water (say 1 gram/250 mls water or something) and use it later, or will the water effect it?
