You are not alone. My Pro press 200 worked fine until I got a new box of investment . 5 splits in the five rings, even with the loaner furnace. I think its the Ivoclar Speed Vest at This point

Interesting. WE started experiencing split rings about a month ago. Ivoclar tried to tell me it was our vacuum mixer. Now that I see this, I have to think there was a bad batch of investment...

I just got a replacement LOT of investment and am using a half ml less liquid with. Full 45 min bench set , 5 minutes sit on top of oven dry time., and a full 45 minute burnout. If there are dark stains on your ring after burnout it is because either the oven is not hot enough or needs more time. 5-10 longer burnout. So far no splits.
