I haven't used any sealer and have not baked them, but they were done with all stazon ink. I guess I will experiment with one tile with the stazon/sharpie combination and check for bleeding before I do a bunch.
I sprayed the coasters to protect the image. I used Krylon Triple-Thick Crystal Clear Glaze, which gives a bright, high-gloss finish, looks like glass, and gives the illusion of depth. I love the look of these - so "finished". I have used one of the sealed coasters for over 4 years and have never had a problem with condensation beading from cold drinks so I don't know why it would be a deterrent from people buying them? To each his own, I guess...
