Hi Douglas.

I think you are looking for the acid of selenium, which is spelled 'selenious'. Give that one a try in your search engine, Douglas. But rather than trying to formulate your own cold blackening solution (there is more to it than the acid), I would strongly suggest that you purchase one from a vendor who has done all the necessary development work for you. See the banner ad at top of the page. Good luck.

Regards,

Ted Mooney, P.E.
