You put them in a standard convection kiln, everything looks fine, and then—<em>crack</em>. It happens because of &ldquo;dead zones.&rdquo; Basically, the hot air just can&rsquo;t reach every nook and cranny of a weirdly shaped piece of glass. You end up with these cold pockets that create internal stress, and the glass snaps during the cooling phase. It&rsquo;s frustrating.
