Thank you all for your kind words about the disastrous firing that ruined my kiln shelves! I had to do something because I can’t afford, nor do I have time to order, new ones right new. I took an awl and a hammer and just kept pounding away until the fired in pieces came off, taking chunks of kiln shelf with them, I dremeled all the razor sharp points down so that they wouldn’t slice my hand covered the shelves with thick kiln paper so that the glaze that is on them won’t stick to any new pieces. My bisque for next weekend fired overnight and hopefully all will be well!
