Step 1
Read the instructions. Yes, even glass bakeware comes with instructions. It's important to read these instructions closely and see how the pieces can be used. For example, some brands can only be used up to temperatures of 350 degrees F. Exceeding these temperature could result in the pan breaking. The instructions will also tell you other safety precautions you need to take with that particular brand.

Step 2
Use potholders or oven mitts. You may have seen your mother or grandmother use kitchen towels to remove pans from the oven. This should never be done if you are using glass bakeware. If the towel is the least bit damp, it will cause your pan to shatter. Using potholders or oven mitts will help prevent the pan from breaking.

Step 3
Avoid broilers and toaster ovens. A broiler is simply too hot and toaster ovens were designed to be used with metal pans. A quick look at your instruction manual will confirm that both cooking applications are ill suited for glass bakeware. Instead, stick with the oven.

Step 4
Let pieces cool before soaking or washing. Placing a piece into the sink before it has thoroughly cooled can cause the pan to break. Instead, wait for the pan to come to room temperature and then wash it.

Step 5
Prevent thermal shock. The reason most pieces of glass bakeware break is that they receive a thermal shock. Thermal shock is when the pan comes in contact with a temperature that far exceeds, or is far below, it's own. For example, taking a pan from the oven and putting it in the freezer would result in thermal shock.
