Re: Manganese drier for oil inks - retailers?
bridog,
i hate to say it but i think your chasing a lost cause.... there's hundreds if not thousands of metalic salts that act as driers.... cobalt, zinc, tin, lead, manganese, vanadium, etc. etc. it isn't the base metal thats toxic it's the other stuff in the salts. take tin... it's a perfectly safe metal, used to line food cans etc. but the best known of it's driers is tri-butyl tin... very nasty stuff. many years ago... like four decades ago. i did much of the research and lab testing on a cobalt excellerator for the plastics industry. very similar to the cobalt drier but not exactly same material and i wasn't limited by percentages instead of 5% solution i was working with the pure stuff. amazing what it would do, speed up setting time from 20 minutes to 5 seconds. anyway i took what i learned there and applied it to my own work with paints, inks and wood finishes. i used coblat salts for a number of years til i discovered the tin driers and have used them for about 25 years now.
what you have to understand and remember is that in the cobalt drier for exap. the art supply stuff is only 5% and your only using a drop or two and diluting it a thousand times or somewhere near that.... your not putting it on your body or eating it or smoking with it on your hands... or i hope your not. so what if you get a little ink on your hands there's so little of it in that amount of ink (unless your a total pig about it) it won't hurt much of anything.... wash your hands and wear an apron to keep the ink off your clothes. all the metalic salts i know of used as driers, oxidizers, excellerators and catalists they are nearly all toxic or such a fire hazard... there's one i won't say it's name you can get at your local drug store or feed store, not toxic, safe and very cheap but if you add too much of it to any organic compound watch out... your ink can burst into flames within seconds.... i'd say that rules it out, what say you? if you really want to use manganese salt for a drier find out which manganese salt it is and i can very likely tell you where to get the pure stuff for you to make up your own solution.
another little note.... hard to trust the msds on the various artists driers.... when for exam. the msds on grumbacher cobalt drier doesn't even say which cobalt salt is used in it.
