Re: I'm back! Hi to all + Silane?
Oh, sorry, it was clear ACRYLIC gesso, which is probably (though I
couldn't get much info on it) acrylic medium with something gritty in
it. My understanding is that it's gritty, which is why I thought it
would make a good sub, but as I said, I haven't seen it or used it
myself.

Clear Gesso? Could it be plain rabbit skin glue then? AFAIK,
traditional
gesso is rabbit skin glue + chalk (calcium carbonate) + (perhaps)
white
pigment (zinc or titanium). I always thought what makes gesso
gritty is
the chalk component. Even a little bit of it would "cloud" the
transparency.
Or, is it clear acrylic gesso (= plain acrylic medium in other
words)? I
guess almost every ready-made gesso is based on acrylic...

Another possibility for a sub for glass is clear gesso, that was
recently discussed on APUG (you can find the thread under Alternative
Processes) as a substitute for gum arabic in gum printing. I'm
somewhat puzzled about that use for it, but it strikes me that it
should make a good sub for gum on hard slick surfaces, as it is
transparent but contains some gritty substance. I've never seen
clear gesso, and Daniel Smith doesn't make a clear gesso, but I've
got it on my list to look for next time I visit an art supply store,
