Yes, but not under normal operating use, breakages usually occur by either closing the door on a log or a build up of rust underneath the glass, which puts pressure on it. This is aggravated if the rope or gasket between glass and door gets wet when the glass is being cleaned. We hold stock of many pieces of stove heat-resistant glass. If it is a piece we do not have, we can have one cut to the correct size. If your glass has a curved edge we may need a template.
