Fall Show – Postponed

Due to all the troubles I have been having with my kiln, I am canceling my show for September and hopefully just moving it back a month to October.  I was really hoping I wouldn’t have to cancel it, but I am just not getting the results I need and my kiln is still acting up after its repairs.  The kiln has brand new elements and a new thermocouple as well.  I had all the electrical work tested to make sure it is still in good condition and receiving the proper voltage.  I even had the control panel tested and everything seemed to be in working order.  I am now firing my fifth test glaze in hopes that it will work this time.  The trouble has been that the kiln is firing very fast and I don’t think it is holding properly at the right temperature to allow for the crystals to grow.  I have tried multiple things:  adding a longer hold to the program, reprogramming the firing cycle, firing pots with fresh glaze applied, monitoring the firing cycle during the hold, etc.  I am getting the right colors, and the kiln has definitely reached its peak temperature, maybe even too hot, just little to no crystals are forming.

Samples of my last four test glaze firings

The kiln is firing right now for my fifth attempt.  I am starting to think about investing in a new kiln so that I can keep up with my firings and have my commissioned work completed on time.  I don’t want to lose any more momentum.  I need something that is going to be reliable and carry me through to the new year.  I am still plugging away at my throwing and creating.  I am starting to run out of places to put my work!

  • It looks like your kiln is over-firing. Maybe not by temp but by time. What cone are you firing to and are you using cones. What is your time to top temp?

    Just asking 🙂ReplyCancel

    • Hi Avi!

      I think it might be too. I have had 5 test fires recently with my new elements and I am not getting the crystals I was getting before. It has been so frustrating. I am firing to cone 10. No, I do not actually have cones. My firing cycle peaks at 2310 and hold for 30 min before dropping for a longer final hold. I am stumped and have spent so much money with nothing to show for it…any suggestions? I would really appreciate them!

  • Arryn,

    If you have not changed your glaze recipe you should be getting the same results. Cones are a must!! They will tell you what the kiln is really doing. I would suspect you have type K thermocouple which is not accurate above 2000º. You should put in a 9-10-11 set on the same shelf as the T/C. 30 minutes at the top with new elements seems long. I usually hold for 10 minutes. How long is your first hold and at what temp? One thing that is good to do is keep a log of start times and time to top temp. Over time (as the elements wear) time to top temp will get longer and you can adjust.
