The glass is really the culprit. It's too smooth to get much of anything

scuff the glass with alox sandpaper, or etch it with acid to give the
glue something more substantial to grip. Even most industrial strength
contact adhesives aren't really good at sticking stuff to glass. They
need a porous surface to bite into.



Maybe I'll switch to clay flowerpot saucers. I'm not wedded to my
glass ashtray.
