What Can Cause Glass to Break in the Oven?
There are many different things that can cause glass to break in your oven. This ranges from your dish being old, or flawed when it is put into the oven, all the way to a quick temperature change from cold to hot. For details, let’s look at what can cause the glass to break in the oven.
Drastic Temperature Changes. When glass encounters a significant temperature change it is much more likely to break because of the quick change.
The Wrong Type of Glass. Another reason why your dish may break in the oven is that it should not be put into the oven, to begin with. Basic types of glass have much lower heat resistance and will break usually in the oven.
Typically dishes that are made for bakeware do not break easily, however, if you try to put glass in that is not intended for the oven, such as plates, bowls, or glasses, they are likely to break easily.
Temperatures That Are Too High. Another reason your glass may break when heated is that the temperature is too high for the type of glass. Because of this, it is a good idea to avoid putting these dishes in an oven at a high temperature.
Check for Cracks or Scratches. Another reason why your glass may break in the oven is that the dish has scratches or cracks in it. This causes structural weaknesses in your glass dish and may cause it to break when heated.

- After your food is baked and your dishes are removed from the oven, allow your dish to cool to room temperature before rinsing in water. Yes, washing a hot glass dish and water can also cause the dish to break.
- If you are placing your dish in the fridge for later, make sure your glass dish cools to room temperature before placing it into the refrigerator.
- The same also applies if you are placing your glass dish into the freezer. Make sure your glass baking dish cools to room temperature before placing it into the freezer. If possible, it’s a great idea to let your dish cool in the fridge for a few hours before freezing it as well.

What To Do if Your Glass Breaks in the Oven
