Johnmicheal Posted December 9, 2017 Report Share Posted December 9, 2017 How long does it typically take to fire a cone 6, medium in a 1227 skutt. I am used to manually firing a kiln. It usually doesn't take more than 8-9 hrs to do a glaze. The skutt is bigger obviously, and the computer controller may ramp more conservatively than my manual adjustments, but 12-14 hrs seems a bit much. The elements don't appear to be bad, no codes thrown for stalled temp, relays all working. I know the box I put on it came from a 3 phase kiln, but I did the necessary conversion, i.e. replaced the power block and wiring, elements were converted to 240 1 phase. Any other ideas?

David Woodin Posted December 9, 2017 Report Share Posted December 9, 2017 Cone 6 profile for a Bartlett controller range from slow of 15 hours, medium 7 hrs 37 min , to almost 11 hours, fast 4 hrs 36 min. You may want to measure the resistance of your elements and compare them to Skutts table for elements/ David Link to comment Share on other sites More sharing options...
Denice Posted December 10, 2017 Report Share Posted December 10, 2017 My 1227 Skutt was taking 12 hours when the wires were worn, I rewired and now it is taking 9 hours for C6. I fire manually. Denice Link to comment Share on other sites More sharing options...

Johnmicheal Posted December 10, 2017 Author Report Share Posted December 10, 2017 Neil, we usually use a medium cone 6 setting Link to comment Share on other sites More sharing options...
Johnmicheal Posted January 10, 2018 Author Report Share Posted January 10, 2018 I measured the resistance of my elements, they were beyond the 10 % you typically advise, closer to15%. I've seen worse looking elements, which says a lot for how much abuse these things can take. Link to comment Share on other sites More sharing options...
neilestrick Posted January 10, 2018 Report Share Posted January 10, 2018 At single phase, that kiln is only rated for cone 8. So once the elements start to wear it will really slow down getting to 6. Replace the elements and you'll be good to go. Link to comment Share on other sites More sharing options...
