ABlanc Posted April 17 Report Share Posted April 17 The kiln gods frowned on me last night. My Cone 6 glaze firing errored out and the kiln only got up to 828F degrees before stopping and cooling back down. The pieces look fine - like unfired glazed pieces but the surface looks a little "cooked" or "toasted". Good to just fix the kiln and give it another go? Or did something happen chemistry wise to the glaze hanging out at 800F that I should take note of before refiring? Thanks in advance!

Pres Posted April 17 Report Share Posted April 17 @ABlancBest bet here is to assess the kiln problem, fix it, and then re-fire the load to ^6. Check your elements to make certain none of them has broken first. If they are in good shape, then the problem is probably in the lead boxes. Is this kiln run on a cone setter or a programmable controller? If in a setter was the cone in the setter still as if unused? best, Pres Rae Reich 1 Quote Link to comment Share on other sites More sharing options...
ABlanc Posted April 17 Author Report Share Posted April 17 Thank you! Based on the error message, it might be the relays which we are checking now, or it the kiln was loaded way too bottom heavy. Elements are all good thankfully. Once we get that sorted we will just give it another go - I had just wondered if I needed to reglaze or fire differently the second time since the pieces already fired at 800 degrees for awhile, but I am just overthinking it.

Dick White Posted April 17 Report Share Posted April 17 At 800 degrees, the glaze particles have not begun to sinter, they are just a little toasty. Fix the kiln and refire. Roberta12, ABlanc, Rae Reich and 1 other 4 Quote Link to comment Share on other sites More sharing options...
neilestrick Posted April 21 Report Share Posted April 21 They won't be affected at all by 800 degrees. Dead relay in the kiln? Quote Link to comment Share on other sites More sharing options...
