Woodsman,
The term "crazing" generally is used to describe small cracks in a ceramic outer coating. As it would relate to the ceramic coating on a woodstove, this could result from a mismatch between the thermal expansions of the ceramic coating and and the (cast iron? steel?) body to which it's attached. In a common usage of the term, crazing would bring to mind widespread cracks, in a relatively consistent pattern. Frequently this is done on purpose, for esthetic purpose. The term would not be generally used to describe the phenomenon of a large piece of ceramic chipping off while the surrounding material remains.
Bottom line on use of the term, I personally wouldn't use this word to describe what you've observed on your stove.
Irrespective of what we call it, the failure of the bond between the ceramic and the metal can be due to the thermal expansion problem described above (materials expanding at different rates as the temperature changes, and the relatively brittle ceramic gets to a point where it can't handle the stress), or it could be simply a bad application of the ceramic. On this latter explanation, I don't have deep expertise in materials science, but from what I do know, it could be sub-standard ceramic material quality, improper surface preparation, inproper firing of the ceramic, the wrong ceramic chosen for application with that particular metal, etc., etc.
You don't state the age of the stove. Still under warranty? If so, I'd be back at the manufacturer real fast. Without knowing more, it's impossible to really conclude this, but I would suspect that this is not the last problem you're going to have.
