gunars Posted February 11 Report Share Posted February 11 Hello! Red clay. Biscuit fired at 995 C Celsius, held for 10 minutes. Clear glaze designed for 1020 C to 1280 C Celsius. Glazed twice in a thick layer with flat brush. Glaze fired at 1040 C Celsius and held for 5 minutes. The third time I fired at 1055 C and held for 20 minutes, but nothing changed. Still the transparent glaze is dull and has large white spots. In a thin layer, the clear glaze is transparent and all is well. I made the eletric kiln myself and it is not commercially bought. Can anyone suggest where I am going wrong? I bought the transparent glaze in a ceramic shop. Quote Link to comment Share on other sites More sharing options...
Roberta12 Posted February 11 Report Share Posted February 11 Hello! The white spots look like the glaze is too thick. I have had the same problem at times. Did you put cone packs in your kiln? That would be the best way to see if your kiln is firing to the proper temperature. Rae Reich, Russ and Hulk 3 Quote Link to comment Share on other sites More sharing options...

Maybe the thermocouple is not showing the correct temperature that I programmed. Thanks for the reply! Hulk 1 Quote Link to comment Share on other sites More sharing options...
