nicethyme's recent pink vase problem reminded me I had the same problem once. I painted my own glass, glued it to my project, and then when I grouted it, the grout process rubbed off some of the glass paint. Then I painted the grout, and even more paint came off the glass. It seemed like such a great idea to paint the exact paint color I wanted onto the glass instead of shopping and trying to come close to what I wanted without success.

Is there any brand of paint that you can use to paint glass and it will withstand the abuse from grouting?

I've also thought about painting ceramic and have the same question about paint that will stay on ceramics and will survive the grouting process.
