[QUOTE="ztech, post: 350422, member: 3022"] I press mine at 902C with 12:30 hold, I am not saying this is what you should use, just pointing out, they are only numbers. I haven't calibrated my pressing oven since I got it. If the pressing outcome changes, I look at the result and adjust accordingly. The thing that makes this possible with me though is that I am a 1 person lab and I don't have to accommodate the preferences of others. I would be more aggressive in the first change but only change 1 thing at a time. If you change more than one then you, don't know which actually affected the outcome. I can say that putting the mass of the Alumina plunger would lower the temp of the mass of material by a few degrees and I think this is where you biggest improvement will come. [/QUOTE]
