Pyrex is a brand of tempered glass bakeware that is oven-safe up to 425 degrees. Some users have reported that their Pyrex dishes have shattered when used in the toaster oven, though the exact cause is unknown.
It is thought that the high heat of the toaster oven may cause the glass to expand and break. Is it safe to use Pyrex in a toaster oven? Let’s find out.
How Pyrex Works?
Pyrex is made of tempered soda-lime glass, which means that it is designed to withstand sudden temperature changes without shattering. Tempered glass is also stronger and more durable than regular glass.
When heated, tempered glass will expand at a rate of about three times faster than regular glass. However, when cooled, tempered glass will contract at a rate of about three times faster than regular glass.
The expansion and contraction of tempered glass are what make it more resistant to shattering than regular glass. When tempered glass is heated, the outer layers of the glass expand faster than the inner layers.
This creates tension in the outer layers of the glass. When cooled, the inner layers contract faster than the outer layers, which relieves the tension in the outer layers. The result is a piece of tempered glass that is less likely to shatter from sudden temperature changes.
Pyrex Dishes and the Toaster Oven?
Most people use Pyrex dishes in the oven, but did you know that you can also use them in the toaster oven? The tempered glass can withstand temperatures up to 425 degrees, making it a good choice for cooking or reheating food.
However, some users have reported that their Pyrex dishes have shattered when used in the toaster oven. It is thought that the high heat of the toaster oven may cause the glass to expand and break.
If you’re going to use Pyrex in the toaster oven, there are a few things you should keep in mind. First, make sure that your dish is appropriately sized for the toaster oven. You don’t want it to be too big or too small for the space.
Second, place your dish on a baking sheet before putting it in the toaster oven. This will help distribute the heat evenly and prevent hot spots. Finally, preheat your toaster oven before adding your food. This will help prevent thermal shock, which can occur when cold glass is placed in a hot oven.
Why Pyrex May shatter in a Toaster Oven?
While Pyrex is designed to withstand sudden temperature changes, it is possible for the high heat of a toaster oven to cause the glass to expand and break. It is thought that repeated exposure to high heat can weaken the structure of the glass over time, making it more susceptible to shattering.
It’s also important to note that not all Pyrex dishes are created equal. Some Pyrex dishes are made with thicker walls than others, which makes them more resistant to breaking.
Additionally, some Pyrex dishes are made with annealed (non-tempered) glass, which means they are not as resistant to shattering as dishes made with tempered glass.
So, how can you tell if your Pyrex dish is made with tempered or annealed glass? Tempered glasses will usually have a label that says “tempered” or “safety glass.” Annealed glasses will usually have a label that says “ovenware” or “heat resistant.”
Is It Safe to Use PyRex in a Toaster Oven?
If you’re planning on using your Pyrex dish in a toaster oven, there are a few things you should keep in mind. First, make sure that your dish is appropriately sized for your toaster oven. If it’s too big or too small, it could cause problems.
Second, place your dish on a baking sheet before putting it in the oven. This will help evenly distribute the heat and prevent hotspots from forming on your dish. Finally, preheat your oven before placing your dish inside.
This will help avoid thermal shock—sudden changes in temperature that can cause your dish to break.
Conclusion:
So, is it safe to use Pyrex in a toaster oven? Yes, but there are a few things you should keep in mind. Make sure that your dish is appropriately sized for the space, place it on a baking sheet before adding it to the oven, and preheat your oven before adding your food.
