[QUOTE="DMC, post: 41800, member: 430"] You are missing info there buddy.... What is the ramp rate or I guess you are calling it the burnout speed? Most guys are holding half-way at 750-800F or so for a while (half hour pre ring)...then resuming the ramp up to high temp at a slow-med rate. The plastic ooze4s kinda slow starting at 750F and if you go too fast up to high temp, you will get casting fins from cracked investment or even exploding rings! It's unclear to me if you even started with a cold oven? [/QUOTE]
