Well I have ordered some laminates from laserpcb.com. I asked them if
they thought it would stick to glass. The support was fantastic. The
reply I got

'I just tried it on a smooth drinking glass, and it stuck extremely well'

So that is initially something. But yes, I think the only way I am
going to find out it to try it. I wonder if over time the tracks might
lift up. I would prefer not to have to conformally coat the board
because I think this board is more just fun and art in a way. I see no
actual practical benefit to it. It just might look very cool. I mean,
i do not even have a project for it. I just really fancy trying it. So
to start with I shall do some fine tracks and maybe a couple of
surface mount components for proof of concept.

The other though I have is along the lines of trying to plate the
glass as suggested earlier. It seems if they can do it with Silver
then why not.
