But I don't hesitate to add that I have never used anything other than 104 (well, there is a lot of Devardi here that is supposed to be 104 but I still follow the 5% rule with that as well) so YMMV.
Please let us know if you figure it out.

Yup...crack straight down the middle, that's what happened. I'm wondering if I am waiting too long to put it in the kiln, in that it cools off alot faster than the 104 does (from flame to kiln).
