I brought several pieces home from Mexico after giving them an initial bisque firing. In my Vermont studio, I applied color underglazes, topped with a satin clear glaze. Made a big mistake — the clear glaze fired at a higher temp than the glazes or the clay, so it remained a white thick paste on top of all the color after firing. I tried scraping it off, no go. Couldn’t fire higher as clay would melt! Only way to save the pieces from the trash can was to try to reapply color using acrylic paint. Results below were surprising OK!
