So what can you do to make sure you’re not in danger of having your glass oven shatter? Here are a few tips that are being passed around from oven manufacturers: Never bump your oven door with pots and pans. The smallest crack or nick could cause a stress fracture that could “explode” at a later time. Never slam your oven door. Never close your oven door without first making sure your oven racks are all the way in. Don’t use the door to close the oven racks. Metal can scratch the glass, causing breakage. Never run the self-cleaning feature on your oven. Extreme amounts of heat can not only damage the internal components of your oven, but they can also cause the glass to break on the internal portion of your oven. Generally, self- cleaning features are a selling point, but you can get most burnt on food in your oven using heat free methods.
