Curto-type / Orotone documentation

Is there documentation somewhere online about how Edward S. Curtis produced his Orotones?

I've been having a go using acrylic paints but mine just look incredibly tacky/naff like a cheap mirror from a souvenir shop rather than the intended subtle work of art!

I saw somewhere Curtis used bronze powder in banana oil but nothing more specific.

hi there

I haven't made them but I have seen some ( well virtually ) you might have found these links already? if so, sorry for my
redundant postings and if not. ..
there are a few people who have posted on this site in the past who have made them and links to a YouTube video ..
