  1. Hi, I have owned a second hand Duncan EA 1020 studio plus kiln for around 12 years and have mostly been firing at the lower temps from cones 020 to 04. Cone 04 usually took around 6 hours. This kiln is an Automatic/Manual kin. 30amp. The Kiln is rated to fire to cone 8. It has a 20 hour timer. Element ohms have been tested and are slightly better than required Recently I wished to fire to cone 6. This has become a sticking point. I did a firing mid last year for cone 6, set the timer for 15 hours. The Kiln reached cone 4 almost 5. The next cone 6 firing was 20hours and
  2. Hi all! I just finished converting an old electric kiln to gas. The firing will be totally manual, no kiln sitter involved. Having never fired a gas kiln, I know my learning curve will be steep! But I need a few pointers to get started. I want to start out with a glaze firing, ^5, mainly because I don’t have any greenware to bisque right now. I have a few “sacrificial pieces” that I am willing to use to start the learning process. I have a pyrometer and witness cones ready to go. So, my main question has to do with ramping at this point. How fast do I want the kiln to increase in
  3. Hello all, Looking for firing schedules. I have a small manual electric kiln with a kiln sitter and wondering if anyone has a simple, clear firing schedule they follow and could share? I am a beginner trying to learn how to fire for Cone 04 Bisque and then another schedule for Cone 6 Glaze Fire. I am using buff stoneware. Any firing tips appreciated! Thanks so much, Natalie
  4. Educational Post Firing Schedule Variables There are several key issues that effect the final firing schedule selected. 1. Functional or Non-functional use. 2. Wall thickness: thrown or hand built up to 3/8". Structural starting at 1/2" up. Sculptural with varying thickness/ parts. 3. High iron/ carbon bodies vs. white body. 4. Single fire vs. bisq. For the bulk of most firings; functional or non-functional and single fire vs. bisq fire comprise most firings. The additional variable is how thick are these pieces? Several universities across the world have done studies
  5. I recently purchased an old Gare ( or Evenheat) Kiln model 2327. Evenheat still makes this high fire kiln but, when I searched their website they only provide a manual for their newer model of the 2327. I am looking for the manual pertaining to the older model 2327. the kiln I purchased is equipped with a kiln sitter model LT-3K which has a timer dial as well. the controller uses a series of 6 (on/off) switches to control which elements are heated, I am also looking for a firing schedule for these switches. If you have any tips or suggestions on operating and firing this kiln please feel
  6. So I was thinking about glazes and I fire my kiln at 108F/h to cone 5 and hold for 60 minutes. This got me thinking about trying orton's other rate of climb. Trying something like 27F per hour to cone 6 instead of using a hold at cone 5. So fire to 2111F, 1965F then climb to 2165F at 27F/per hour. I was wondering if anyone has tried this type of schedule? I am curious at the differences it would make in my glazes. Instead of going straight cone 6, changing to cone 5 with an hour hold improved my glazes a lot. It got me thinking about trying this. Anyone fire at that final rate of 27F/h? D
  7. I've just opened my first firing with Hesselberth/Roy's suggested firing schedule for cone 6. I was surprised to see that my glazes turned out way more matt than usual (see photo of two pots, same glaze) as well as having a complete color change with my layered blue. Has anyone else experienced a complete change (for the worse) when using this firing schedule. I've rechecked the programing and it was entered correctly. Maybe having 3" brick on my kiln changes the game??? Would love some input. I'm refiring this load and hoping to salvage it.
  8. I have a new Paragon Kiln TNF-82 with a 12 key Sentry digital controller. I am so very confused as to the firing schedules. Ie. ramp up. Cool down etc. I used to own a manual kiln with a kiln sitter. I just put the bar in and it shut off when done. Now, can I fire the same way, or do I need to do a ramp up and slow cool? I am firing 12 x 12 x 1/2" tiles. First to bisque, then to ^6. I plan on stacking 4 on each shelf as suggested by an expert to bisque. Do I need to slow cooling down? Does anyone have a firing scedule for bisque and glaze firing I could follow? Its taken 3 weeks to dry the
