Re: formulas for S2 and S30

Hi Ryuji,

My procedure is basically Jolly's in a nutshell--that is my original source.
He says the S2is a dilute potassium hydroxide solution, perhaps 5% but he
doesn't know, and the S30 is an acetate buffered thiocyanate solution.
That's as far as I know. I'll read up on all my info again and see if I
can glean anything. I've got Lam's article, Bean's article, Jolly's, Dan
Burkholders, etc...but all use the proprietary name of Kodak s2 or S30,
except Lam actually recommends Porter's chemistry.

Maybe I can get a MSDS sheet on them...
