Here is the witness cones. and below is the schedule 1 200/350 0 2 350/1100 0 3 350/1953 5 4 108/2167 0 5 9999/2053 30 we are still running in to pinhole problem, but isn't as bad as before. packing the top and bottom light, and middle heavy. for my understanding our kiln still run too hot. not sure how to fix that. should I try firing to cone 4 and hold to cone 5?

the reason I run the first segments is because the studio I'm in right now are full of students and new members, all on different levels, also not sure how long their pieces been sitting there. the preprogramed didn't work too well, lot of the pieces come out with defects. the witness cone on top and bottom shelves are band but didn't seem like it hit cone 5, and middle is drop to the point the tip is touching the shelf. I don't have photos right now, but I'll add them when I have it.

Hi all, I'm in search for a good cone 5 firing schedule that create the least amount of defect, we are firing a new skutt kiln KMT1027-3, they use to firing on preprogram cone 5 schedule and are running into defects problems like pinhole and blisters. I search around the wed and come up with this schedule, step °F/hr / F Hold 1 200/180 60 2 200/1100 0 3 350/2053 5 4 100/2153 0 5 9999/2053 30 but still seeing pinhole on some glaze, is it the glazing issues, or a firing issues? I would love to hear from you guys.
