[QUOTE="Toast, post: 18545, member: 1037"] wwcanoer, I don't think there is anything special about prog. #33, its just the number I chose and happened to be outside of the 11-20 range. There must be something special about prog. #'s 11-20 though if ivoclar says to use that range for emax, but I don't know what it is. I'm pressing 200g rings at 910C with 15 min. hold and getting a light reaction layer and super sharp margins, yes its been calibrated recently. I've always looked at ivoclar's parameters as a starting point, all ovens are different. I have to fire dsign 10*C higher the they recommend in my P80 oven. Keep lowering your temps like sixonice suggested and try a program # out side of 11-20 with the same parameters and see if you have the same results I did. Good luck. [/QUOTE]
