What would you do?
The (community centre) kiln now has new, evenly coiled, non-droopy elements, and it overfired. Cone 7 was well down with the programmer set to 1241C, with final ramp rate of 150C. - I checked the cone packaging before setting the programmer and wanted ^6.
So, should we get the kiln techs back to re-calibrate/adjust the programmer? The ones who said there was nothing wrong with the droopy/stretched straight elements . It's a MITSCO 3000 I think, or should we just drop the final temperature.
It also overfired on ^06, but as we didn't have any cones we don't know by how much but I can tell by some of the glazes. We now have cones, so will be checking the result next glaze firing. The kiln fires unattended overnight so the tutor has never bothered with cones, but I always use them for ^6.
