Its best to put the dish on a dry dish towel or a metal cooling rack to cool. Damp towels or surfaces can also cause the hot glass to shatter. Dont use tempered-glass bakeware on the stovetop, under the broiler, in a toaster oven, or on a grill.

What would cause a Pyrex dish to explode?

When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. If the stress is too extreme, the bowls structure will fail, causing a spectacular shattering effect.

Why did my glass pan explode?

When glass goes rapidly from something cold to hot (like a freezer to an oven) or vice versa, it can experience “thermal shock.” Different sections of a piece of bakeware can expand or contract differently and cause it to lose its structure, resulting in a shattering effect.

Why did my glass casserole dish explode?

Putting a hot pan on a cool surface, or roasting at high heat without enough liquid may cause problems. According to the company, All glass, even borosilicate, can experience thermal breakage if exposed to sudden or uneven temperature changes. Never put glass bakeware directly on a burner or under a broiler.

Can Pyrex explode in the oven?

Pyrex, a household staple for nearly a century, has recently been found to break, shatter and explode when being used for cooking or taken out of the oven. Pyrex bakeware is putting consumers in danger as it has been found to shatter and crack during use, which many believe is due to the quality of the glassware.

What Pyrex bowls are worth money?

Patterned Pyrex—such as the 1956 Pink Daisy or the 1983 Colonial Mist—also tend to be valuable as a collectors item. Some patterned collections, like the 1959 Lucky in Love heart and four-leaf clover design, have been valued as high as $4,000 for one bowl.

Can Pyrex explode in the microwave?

When a cold bowl of Pyrex is heated rapidly in the microwave, then its parts will contract or expand at different rates which will cause stress to the glasslike material. The structure of the bowl will not be able to handle this much stress, therefore it will break or explode.

Can glass explode in the oven?

However, its common knowledge that putting glass in high heat can cause it to shatter. Any oven safe glass or tempered glass is made heat resistant to withstand the high oven temperatures we use for cooking and baking, so its good to go!

Can glass shatter from heat?

When Can Glass Shatter from Heat? Glass is a durable material that stands up well to summer heat. However, Glass can suffer a thermal break when the temperature gets too hot. Thermal breaks tend to occur when the glass expands and contracts due to temperature differences.

Can Pyrex go in a 450 degree oven?

Pyrex is meant to be able to withstand higher temperatures. Pyrex can be used safely inside an oven that is less than 450 degrees F. Whether or not its inside a conventional oven or a convection oven, this glassware will be safe to use so long as that temperature isnt exceeded.

How do you know if a glass is oven safe?

For one, you should check your glassware for any cracks or scratches before using it. Even being oven safe wont protect a glass that is on the verge of breakage, and it will likely shatter once exposed to high heat. Along with this, many glass dishes labeled as oven safe still have a temperature limit.

How high can a glass pan be in the oven?

High Temps Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans.

What happens when a piece of glass is exposed to intense heat?

The glass breaks on heating due to thermal shock. Whenever there is difference in temperature between two surfaces of the glass, the thermal expansion of one side with respect to other side induces stress in the material. When this stress reaches above the yield strength of the material the cracks start to develop.

Can glass just shatter on its own?

Exploding glass is a phenomenon by which toughened glass (or tempered) may spontaneously break (or explode) without any apparent reason. The most common causes are: Binding of the glass in the frame, causing stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind.
