    Kiln not reaching temperature

    Hmmm... It is a 32amp plug so it goes straight to the fuse box, although it has to travel quite a long way. Maybe that is the issue. Well, the controller allows me to set a deg/hour rate, which I set according to a firing schedule I researched. So from that I can work out how long firing should take to reach a certain temperature. Assuming it actually heats up at that rate, which on the Bisque firing it did. Is it normal for the temp rise to slow down as it gets hotter? Perhaps I am being naive to think it would rise at the rate set on the controller? In the end it was going for 18 hours and hit 1239deg and I switched it off as I didn't want to leave it overnight knowing it might not be functioning very well. I don't mind if it takes a long time to reach temperature, but the fact the temperature keeps dropping then rising again suggests to me that it is not right.

    Kiln not reaching temperature

    Thanks Mark. I don't have a bung for the top hole in the lid. Would leaving this hole "un-bunged" prevent it reaching temperature?
  3. I have just bought a second hand top loading electric kiln (Potterycrafts P5976 Electric Toploader). I completed a bisque firing to 1000 deg successfully. I have been glaze firing today to 1240deg but from about 1170deg it has been struggling to gain temperature. And at times it drops up to 10 degrees before it goes up again.I have two bungs in the holes in the side but not one in the lid. I'm fairly new to this so not sure if that is correct or not. Any ideas what the issue might be? The person I bought it from said that the elements were replaced recently.I'm not sure what to do now because its been firing for waaaay longer than expected and still not up to 1240. Any advice for a newbie would be greatly appreciated!Thanks
