Are Glass Bowls Oven Safe?

Adding an oven to our daily kitchen routine has become a habit, and that’s why we always try to buy oven-safe items. In contrast, glass bowls are one of the everyday items in every kitchen, and due to the sensitivity of glass, it is essential to find out whether they are oven-safe or not?

Are Glass Bowls Oven Safe?

Glass bowls are generally oven-safe and can withstand temperatures up to 350 degrees Fahrenheit. Despite the characteristics of glass to generate and store heat, the shattering and cracking of the glass bowls in the oven is quite common. However, the situation differs if the glass bowl is handled with care. It would be best to avoid a sudden temperature change as the glass is more likely to break.

With the right care of the oven-specific glass bowls, you can reduce the crack or shatter risk. The only thing you need to know is what your glassware can and cannot handle. Changes in temperature, thermal shocks, and using the wrong type of glass cause breaks in glass. After you have checked that all conditions have been met, the glassware may now be placed within the oven.

It is important to keep the glass bowls at room temperature before using them and place them in a preheated oven. Also, If you are planning to buy a glass bowl, be sure to check that it’s labeled as oven-safe.

How Do You Know That Your Glass Bowl Is Oven-Safe?

Usually, the glass cookware is oven-safe except for those with metallic painted edges. You may put it on the baking sheet, fill it up with water, and place it in the oven at 350 C for almost 10 min.

The primary precautionary measure is to predict that water is present within the bowl and the temperature inside the bowl depends on the boiling point of water or is lesser than that.

When the evaporation of water begins, the temperature rises until the food starts charring. However, you can prevent glassware breakage in the oven by using tempered glass and avoiding sudden temperature changes. Also, identify the weakness in structure and fill some liquid at the base for dry foods.

You can use all the glass cookware in the oven except those decorated or screen printed.

Types of Glass Bowls

As with glass cookware and bakeware, you must be careful while baking at extreme temperatures. There are some of the oven-safe glassware listed below;

1. Pyrex Glass:

Pyrex glass is one of the great inventions that changed the cooking scene in your kitchen. It is a low thermal expansion glass product that you can safely place in the oven. Pyrex glass can bear heat up to 450F, so you can easily bake the products for which hot temperature is required.

2. Borosilicate Glass:

You should know that Pyrex is not only an oven-safe glass. Borosilicate is another type of glass that shows a low coefficient of thermal expansion. This glass can easily withstand the hot oven temperature up to 752F for a few minutes. It indicates that the glass won’t break or crack at high temperatures.

Borosilicate glassware also has high thermal shock resistance, meaning you can wash it immediately after baking without the fear of breaks or cracks.

3. Tempered Glass:

Tempered glass is another type of oven-safe bakeware. Its durability is 5x that of regular glass because the process of tempering increases its toughness.

How to temper the glass? The thermal and chemical processes are used for tempering the food-grade glassware or containers. The most common type of tempered glass is tempered soda-lime glass. The properties such as low coefficient of thermal expansion and high thermal shock resistance make it oven safe.

An added benefit of this glass is that the chances of breakage reduce to 65 to 70 percent to ordinary drinking glasses.

Safety feature: the tempered glass breaks into round, small pieces instead of sharp chunks, lowering the chances of injury.

Before putting the glass bowl in the oven, determine if it’s labeled as ‘oven-safe.’ If you are using such kind of glass, you have probably reduced the chances of fracturing and shattering.

However, to avoid the glass shattering in the oven, be careful about the big thermal shock. So follow the manufacturer’s directions and let the glass get to room temperature before placing it in the oven.

Care Tips For Glass Bowls:

While putting the glass bowls in the oven, you must consider the following safety measures:

Make sure that you use a tempered glass bowl as its oven-safe.
The rapid temperature change can cause cracks in the bowl, so avoid the thermal shock and change the temperature gradually.
Gloves are compulsory for taking out glass bowls.
Make sure that the bowls are cooled entirely before washing them.
Don’t put the glass on the stovetop.

Can You Bake in a Glass Bowl?

You can’t bake in the glass bowl. Why? Because glass doesn’t heat up quickly, but if once heated, it retains the heat for longer. Additionally, this much heat activates the Double action baking powder.

Ideally, you can use light-colored metal pans for baking. As metal is the best heat conductor, this property makes the baking process rapid. On the contrary, glass is not an efficient heat conductor, and batter baking takes long. However, if you are interested in over-bake brownies, a glass pan is a good choice because its center takes longer to cook thoroughly.

Instructions in case the glass shatter

If your glass bowl shatters, you should follow the following guidelines.

Before cleaning the shards of glasses, protect yourself. You should wear gloves, goggles and use a metal spatula or kitchen tong as a picking tool.
Let the oven cool down, then scrape off the chunks of glass and food.
Inside the oven, sprinkle the baking soda solution and let it stay there for a few hours. Later wipe it off to remove stubborn food residue.
Use the small portable vacuum to ensure the complete removal of shards of glasses.

Conclusion:

Many people are concerned about baking in a glass oven because of its breakage. Breakage is an option for glass bowls, but the chances reduce if you follow the labeled directions. You should also not crack or scratch the glass bakeware and ensure the cooking and cleaning are under safety measures. Be mindful of the precautions and let your glass bowls fare well in the oven.
