Hi Robbo, seems only one size got up to that headline expansion rate of 590 all the rest well below, but there even seems to be something odd about that test result as it's the only one that then has a lower expansion rate at the 1000 degree level, it was back to 500 for that whereas all the other sizes went up on the 1000 degree test. Perhaps the stuff starts to shrink again at the 1000 degree mark or perhaps they got the 800 degree result wrong. Funny that the "best" result has such an anomaly from the rest of the test results.

Just wondering if it was supposed to be 490 at 800 degrees then 500 at 1000 degrees.

Something odd about it anyway in comparison to the other results imho.
