I have an old second (third? fourth?!) hand kiln that should be able to reach up to 1300 degrees but seems to be getting stuck at around 200 degrees less than I need. I managed to do a bisque firing but when trying to do a glaze firing the kiln stopped at 1075 degrees celsius and then started to cool whilst still on. The controller (Ipco 3300) showed 'END' even though it had not reached the temperature I wanted and did not show an error message. I have no idea about the history of the kiln, when the elements were last changed etc etc. I (think I've) checked the controller settings to make sure nothing is set to hinder the maximum temperature. I have read about working out if it is the relays or the elements? I am a total rookie so don't really know where to start. Is this the best first move to troubleshoot the issue? Or could it be something simpler?

Hi! I have a (pretty old) second hand kiln that I tried to heat up today - just to test if the elements work - and, surprise surprise, absolutely nothing happened. As I say, the kiln seems pretty old and I expected it to struggle a little bit but to not even try to heat up... Does that mean there's probably a different issue other than the elements just being old and a bit worn out? Would even old elements do something? Any suggestions on where I could start with the troubleshooting? Thank you!

Hello everybody! I am quite new to ceramics and I was wondering if it is possible to leave pieces unglazed. It concerns a series of handbuilt tealight holders, so even though it is functional pottery, they will not be used for any food or beverages. The types of clay I have used are the numbers 354 (980-1200 °C), 366 (1000-1120 °C) and 376 (max 1240 °C) from Have a good clay (I think it used to be called Goerg&Schneider). I like the structure and colour of the clay (especially when the tealight itself is lit and illuminates the chamotte) and I wish to keep it after firing the pieces. Is glazing a must for every piece of pottery? And if it is possible to leave them unglazed, should they be fired twice (and to which temperature)? Also, will the pieces be more brittle and fragile when they are not covered by the glaze? Thank you very much in advance! Any help is very welcome!:) Have a good day!

Hi, I am looking for some advise if possible. I fired my kiln last night but the kiln didn't reach full temperature. I looked at the cone I have in my cone stand and it is not melted. The cone in the sitter either melted or fell off and the kiln shut off. Can I re-fire? As I have not unloaded it, can I just turn it on? Thanks Mal

Please help me. I can’t figure out what stoneware clay my kiln could handle. I recently purchased the Jen Ken AF3C 11/9 Ceramic Kiln. It’s Max temp (as stated) is 2100* or about cone 3. The problem is I need a functional ceramic that’s not too porous so avoiding earthenware. Does anyone know what type of clay I can fire at the temp? Or am I coming at this problem the wrong way? Thank you so much for your help!
