Hi - Absolute complete newbie here! I am painting tiles with Mayco Stroke and Coat with 2-3 coats of clear glaze on top. After firing to cone 06 some of the tiles have bumps which I believe are foreign bodies that maybe fell off the shelf above and became embedded. Can I wet sand, reglaze and refire? (I'm guessing it's not that simple).
Any help would be greatly appreciated!
Thanks
