Hi Andrea
I'm test firing a kiln and I need your opinion. Cone 6 in the ASD, cones 5,6 and 7 witness cones. One set on bottom shelf by peephole and one set top shelf by peephole. Kiln set for high fire. The safety timer knob set for 20 hours. The kiln is empty because I'm test firing and I'm very new at this!!!
So the kiln finished firing and cooled. I open to collect the witness cones. Top shelf cones are what they should look like for cones 5,6 and 7....I'm happy with that. I remove the next 2 shelves for the next set and the witness cones are white and standing straight up???? Why would this happen??

Is this a new or used kiln and what was your firing schedule? Denice

Hi Nancy,
Sorry it's taken a while to see your post. I'm afraid I'm really the wrong person to be answering this question. You should put it to the forum. My kiln has a temperature difference between the lowest and the highest shelves and this factor is always the case. This also happens with the way you load your kiln. Top heavy or bottom, biggest pieces in the middle or at the bottom, etc. Have you fired anything since? It may also help you to take a photo of the load prior to firing so you can see how your loading is affected with regard to the cones. Curious as to why you set your safety timer to 20hrs, Hope you have fun with your new kiln. Andrea
