Hi Ken,
I can understand the brickwork breaking down. Depending on its mineral make-up, one of the things I can remember from my metallurgy training was volume changes in refractory materials with temperature, both on the way up and when cooling off - with about a 10% volume change on the way down.

That's one of the reasons you can't stop things like blast furnaces and coke ovens batteries in the steel industry - the brickwork falls to bits when they cool off.
