When you bisque fire it is important to have the kiln on hold for 20 minutes after it reaches the bisque max temperature. This insures that is shrunk completely. If this isn't done then when you glaze, even though it's a lower temperature, as the mug cools it shrinks more and the glaze is staying larger. That makes the glaze ping pop loose from the mug. Careful the glaze is glass but if you squeeze the mug sometimes you can make it ping and the glaze will pop off. This also happens if the mug had any clay dust on it. That will also cause the ping and loss of glaze. If nothing comes off with squeezing put it under water to see if any cracks show up. Good luck, in the beginning doing Wish List number one I had this happen to me and I had to make pieces over again. hang10tiki did you make the pinging sign? Coconut mugs are fun to make and to glaze. ======================================= During some free time I examined the Tiki Bob's I have in plastic bags in the garage. I found one that had completely dried out. It's hard to carve these because they are brittle but I gave it a shot and did a spiral Bob. I used a dental tool. It was sharp enough that it didn't chip the clay too badly. This is where I quit because my hand was wearing out. ==================================== Then I got out one of the Fogcutter mug blanks to carve. I'm really enjoying these new mugs. It was worth the work of making the 3 molds. =========================================== BEWARE PLAYING WITH CLAY IS ADDICTIVE. =========================================== cHEERS, wENDY [ Edited by: danlovestikis 2015-03-18 20:50 ]
