Ceramics.np.04 Posted December 18, 2022 Report Share Posted December 18, 2022 This is only about the sixth firing I've done with my kiln but it is verrrrrry old and a little worn out HOWEVER recently the temperatures where I live have been around -9°C (16°F ish) and my kiln has obviously taken a little longer to reach the desired temperature out in the shed/studio. I forgot to put a cone pack in this firing but it's obvious from the results that something has gone a bit awry. Glazes that are normally very stable have become a lot more fluid (and ran off), underglazes have completely burnt away etc etc. I don't really know what I'm talking about but is it possible that because it took so long for the final section of the firing to reach the desired temperature (1240°C/2264°F) that it was too hot for too long? And if so, is there anything I can do to counteract this? I stupidly decided to make all my christmas presents this year and, after the disaster of the last firing, I'm scared to do my final glazing with the crazy winter weather. Thanks in advance! I hope at least some of this made sense. Quote Link to comment Share on other sites More sharing options...
