Can you bake acrylic paint onto glass?

Question

Im making some mugs, and I painted some designs with regular acrylic paint? How can I get the paint to stay on there? Can I bake them in the oven? ....Just curious..Thanks

Answer 1

You can bake it on (about 200-250 degrees --in a regular oven, not a kiln which would be way too hot-- for not more than 10 minutes, I'd guess) but that won't keep it from being peelable unless it's attached mechanically (all the way around and connected, for example) or it's never handled much.

Instead of that though (after drying the paint thoroughly), you could just cover the paint and the glass too with one or more coats of of clear acrylic finish** (like indoor water-based Varathane for wood, for one... or permanent "white glue" thinned with water or one of the special "decoupage" mediums, etc.) ... any of those should dry clear and act as a pretty good mechanical hold for everything underneath.
I'd try avoid the lip area of the mug though, and the if hot liquids are put in the mug they may soften those acrylics a bit... not sure.
Also, I'd vote for hand-washing to keep the acrylics in good shape as long as possible.

(And next time, use a different kind of paint... glass paint, Pebeo, etc. )

**let dry between coats


EDITED TO ADD:
I saw yesterday on a TV program that there is an "enamel" paint for glass, but don't know anything else about it.
It was being used by a glass artist to paint onto sheets of glass, which were then "thermoformed" (think that's right), or slumped over or into forms, in a kiln to shape them a bit.
Maybe you could ask at an art supply shop (should ask there anyway probably ) or not sure where glass workers get their supplies or if all types of glass working supplies would even be at one place.
