Hi Carmen, you can find out where to get rottenstone from a craftsman
jeweller...but to clean and prepare glass for gelatine, I use a hot
detergent wash followed by a careful clean (all over not just the print
side) with methylated spirits, followed by a coat of a preparation
formula for painting on glass and ceramics. There a quite a few of these
products around and I'm ptreety sure the main ingredient is isopropyl
alcohol. Hope this is some help.

Subject: cyanotype on glass ( how to clean the glass and other stuff)

Dear list,
A student of mine (Kelly) wants to do cyanotype on
glass. She has been fallowing Galina's technique
published in the Christopher James book, but we canít
figure out with what to clean the glass. I found that
the C. James book recommends something called
"rottenstone" but I donít know what this is or where
to get it.
And a couple of more questions: The formula for the
sensitizer calls for one part "prepared" gelatin to
two parts sensitizer, is this prepared solution a
combined mix of gelatin and hardener such as glyoxal?

What is the easiest way to coat the glass?

Thank you kindly

Carmen and Kelly
