We have all thought about this question at one point in our lives. And if you have finally decided to do some research then here is everything you need to know about putting glass in the oven.

Yes, glass can be put in the oven. However, this heavily depends on the type of glass being used. As you may already know, not all glass products are built equally. Therefore, there are those that can take up much heat and others can’t.

Before you put your glass container in the oven, there are some precautions you need to take. Understandably, glass cookware is an excellent choice when baking or heating leftovers. However, many people have experienced first-hand, the shattering of glass in the oven or immediately it is placed on a kitchen counter.

Only oven-safe glass cookware can be used to heat food in the oven. Regular glass containers should not be put in the oven as they will crack when the temperatures go beyond more than they can accommodate. Other kitchen items that should also be kept from the oven include pots, plates, aluminium foil, cardboard, and paper towels.

Why Does Glass Break When Put in the Oven?

There are a couple of reasons why this may occur. They include;

  • Thermal Shock

The above is usually caused by drastic temperature changes. Thermal shock is the main reason why glass shutters when it is put in the oven. The physical composition and structure of glass can’t accommodate rapid temperature fluctuations. When you take your glass container from the fridge and put it directly into the oven, there is a huge possibility of breaking it.

  • Using the Wrong Type of Glass

Have you ever put a glass plate in your oven and heard a voice at the back of your head asking you; is it safe to expose this type of glass to high temperatures? Well, your intuition was right. As mentioned earlier, not all types of glass should be put in the oven. If it’s tempered glass or oven-safe, then it will handle the rapid temperature fluctuations. But, if it’s not. You are probably aware of what will happen.

  • Exposure to Extremely High Temperatures

Similar to other materials, glass does have a temperature limit. Most of us rarely consider this when using glass cookware. Every glass brand often shares its glass temperature limit in the packaging. If you are keen when opening your glassware packages, you have obviously come across this information. It is crucial that we don’t exceed that limit when using glass in the oven.

  2. To be on the safe side, stick to average temperatures when using glassware to cook in the oven. Confine your cooking to not more than 350 F.
  3. Avoid making drastic temperature changes to your glass containers. This includes taking a glass bowl from the fridge directly to the oven.
  4. When using glass cookware to prepare dry foods, add liquids to the bottom. This will allow the water to warm up gradually as the glass heats up.
  5. Embrace the habit of looking for observing structural weaknesses before sending glass to the oven. No matter how small that scratch looks, know that putting it in the oven is risky.
  6. Never use glass on a stovetop.
  7. Before putting your glass cookware, always preheat the oven.
  8. When washing your glassware, don’t scratch or poke it. Glass must be handled gently to prevent breakage.
