Incompatibility cracks are usually not going to break in half straight down the mandrel. Donna's beads have a thermal shock problem rather than incompatibility, I'm pretty sure.
As far as any kind of cracking goes, I have read dozens of threads over the last 11 years that I have been lampworking and many of them are referring to clear encasing and incompatibility cracks. That's why everyone needs to be careful with clear and do a little research and take notes on what colors and particular brand combinations other artists have found to be problematic.
