I experimented with making cyanotypes on glass a year back or so. I coated the glass with albumen and mixed the cyanotype emulsion in a gel median. It stuck to the glass, but I moved on to other things before I could really see how well it worked. I'd probably use a hardened gelatin instead of the albumen today, (maybe omitting the gel median as well).
And you could probably use a UV protecting varnish to help with the fading, but I'm also unsure about the effect of heat.
