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
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
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
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
