Causes Of Broken Glass In The Oven
Although we have said earlier that glassware can be used safely in the oven, there might be situations that can initiate the breakage of glass in the oven.
Your glass might break in your oven because of the following:
The wrong glass type
Another factor that can result in glass breaking in your oven is using the wrong type of glass. The recommended glass type to safely use in your oven is tempered glass.
Non-tempered glasses like drinking glasses should never be allowed inside your oven.
Ensure that the glasses you put in your oven are marked as oven-safe, and the ones that are not marked as oven-safe should not be put in your oven.
Sudden change in temperature
Thermal shock is one of the primary reasons for glass breaking in the oven. Glasses are not meant to withstand extreme changes in temperature.
This means that transferring your glassware from the refrigerator directly to the oven can increase the chances of your glassware breaking.
This is where applying caution comes in. To elongate the durability of your glass cookware, do not switch it between extreme temperatures.
Extremely high temperature
What most people do not seem to know is that glass has a temperature ceiling. There’s a limit to the intensity of temperature it can safely cook in.
Fortunately, different glasses have different temperature ceilings depending on the process it was manufactured and the manufacturing company.
Luckily, the companies are always kind enough to recommend their products range of temperature ceilings. You’ll likely find these recommendations on the surface of the glass.
Preventing Glass Breakage in the Oven
Preventing your glass cookware from breaking is not difficult. You just have to be careful and handle it with care.
Some of the precautions you need to take are:
Switching between extreme temperatures
As I stated earlier, glassware cannot handle temperature switches. When you remove your glassware from the refrigerator, do not put it immediately inside the oven.
It’s advised that you allow it to stay under room temperature for a while before putting it into the oven. You might have been transferring your glassware from the refrigerator to the oven without any issue, but you’re increasing the possibility of your glass dish breaking.
This also applies when transferring your glass bowl from the oven to the refrigerator.
Do not, I repeat, do not put your hot glass bowl directly into the freezer. You can use our guide on how to properly freeze glass to avoid breaking your glass.
Your glassware will most likely break, even if it doesn’t, you’re weakening its durability and running the risk of it shattering at any moment.
So, what to do? When you remove the glass bowl from the oven, allow it to cool for a while on the sink or counter. When it has attained room temperature, you can then proceed to place it inside the refrigerator.
Make use of tempered glass
It is common knowledge that you shouldn’t put any kind of glass in the oven. Non-tempered glasses are a no-no for your oven.
A glass that is safe for your oven is usually tempered or labeled as safe for the oven on the body. Most times, a note of the accepted temperature range is also listed on the label or body of the glass bowl.
Strict compliance to the temperature ceiling is the first step to ensuring the durability of your glass cookware.
Strict compliance. That means that smaller glasses, lids on some of your glass dishes, and drinking glasses are out of the question unless there’s a clear indication that they are safe for your oven.
Maintain ideal and acceptable temperature
For every glassware, there’s a temperature ceiling. The temperature ceiling is usually listed on the body or label of the glass cookware.
The list is not a decoration. Far from it. It is there to remind you that you should not get to that temperature. Talk more of surpassing it. That is if you care about the safety of your food and glass.
The temperature ceiling ranges from 350° Fahrenheit to 500° Fahrenheit. To reiterate, do well to use your glassware below these ranges.
Check for cracks
Before using your glass bowl, inspect it for structural weakness. If you notice any crack or scratch, it is a sure sign that the technical structure of the glass bowl is weak or deteriorating.
Such scratches call for extra caution because if the glass is made to go through any change in temperature, it will shatter. We don’t want that now, do we?
If food is dry, add water to the glass bottom
If you are using glass pots or on to bake, you’ll need to add some liquid to the bottom of the pot or pan. This is very effective in preventing your glass pot or pan from breaking since it helps the food inside to heat up without scorching the pot.
Now instead of the glass expanding, the water at the bottom of your dried food would expand and reduce the effect in your pot.
Benefits of Using Glass Pots or Pans to Heat Your Foods
Heating your meals with glass pots or and comes will have a lot of outstanding benefits. But this is not usually why most people use glass pots or pans to cook or even hear their food. They do so because it happens to be the only option they have.
Let’s look at these reasons together. Perhaps it will motivate you to get a glass container, pot, or pan, that you could use to heat your food.
Free from toxins
One of the most important benefits of using glass pots and pans to heat your food is that they are not toxic to your health or even the environment. Some bakeware and cookware, when used to heat substances, release some chemicals and toxins into the food.
Heat is retained for a longer time
Surprising how one of the benefits of using glasses is also one of the reasons glasses are not used.
Because glasses are poor conductors of heat, they can retain the heat in your food for a very long time. Except your glass pots or pans are made from fiberglass.
Mind you, this quality of glass also makes it very difficult to heat glass. So it takes a long time for your food to heat up as well. Except for cookware made from fiberglass.
Clear and clean surface
One of the most important benefits of glass is the opportunity it gives you to be able to see your food while it is cooking.
You may be wondering, what is the importance of seeing your food content while it’s cooking?
Well, for most pots, you can only see the top, so knowing when your food is ready or dried becomes difficult.
But with glass pots, you know how long is left for your cooking by just looking at them.
Can be reheated and frozen
With other kinds of pots for cooking, you have to do some transfer before you can heat your food or put it in a freezer. But with glass pots or pans, it is not the case.
You can heat your food in the glass pot and also freeze it in it. You just have to make sure the pot completely cools down before putting it in the freezer.
Glass is easy to clean
This is one of the best benefits of glass pots for heating your food. Glass pots and pans can be easily cleaned without any hassle.
