Pyrex oven crack#

Add liquid to the pyrex bowlР”В®ven the pyrex website suggests to РІР‚Сљadd a small amount of liquid sufficient to cover the bottom of the dish prior to cooking foods that may release liquidРІР‚Сњ. There are several measures you can take to prevent any possible damage to your pyrex bowls. Contact with Heat SourceР”Р„ccording to the Pyrex website, pyrex bowls should not be placed in the broiler, over the stove, on the grill, and directly to the heat source to prevent damage. Uneven heating in the oven can not only lead to undercooked or overcooked food but can also damage the pyrex bowl resulting in breakage. If exposed to extreme temperature changes, the pyrex can explode in the oven. According to the pyrex website, the bowl should be allowed to cool down before any further cooking. It can endure temperatures ranging from 446РІВРЏ to 914 РІВРЏ. Sudden changes in temperature can cause damage to the bowl thus should be avoided.

Pyrex oven crack#

Why does pyrex crack in the oven?Р”Р‡luctuation in the temperature, uneven heating, and direct contact with the heat source can cause breakage, however, pyrex dishes made before 1988 are less likely to crack under extreme temperature changes as it is made up of Borosilicate glass rather than Soda-lime glass which is used to make pyrex bowls now. The following reasons are why pyrex can crack in the oven. However, some measures must be taken to ensure safety and avoid damage to the cookware.

Yes, pyrex bowls are oven-safe and can be used for baking and cooking anything in the oven.

Pyrex, in its current incarnation, should be treated more like any other piece of glass. Do not change its temperature rapidly, regardless of what the website says. Since Pyrex is no longer made of the same special thermal shock resistant glass, one should take extra care when using it. Glassware products can go directly from refrigerator or freezer to a microwave, convection, or preheated conventional oven.РІР‚Сњ The Pyrex website makes no mention of a change in materials, and does not specify what type of glass is used in their products. Also, Pyrex is no longer made by the original manufacturer, and is essentially a brand name, rather than a material. Currently, Pyrex is made of soda-lime glass, presumably as a cost-cutting measure, as soda-lime glass is very inexpensive. Pyrex bowls were originally made of something called borosilicate glass, which is very resistant to thermal shock. Taking a bowl directly from the freezer and putting it into a hot oven might also trigger breakage. Stove tops and broilers conduct heat quickly, and will likely cause the bowls to fail. The main way to avoid this effect is to be mindful of how quickly you change the temperature of Pyrex. If the stress is too extreme, the bowlРІР‚в„ўs structure will fail, causing a spectacular shattering effect.

When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. The text book definition of thermal shock is: РІР‚СљStress produced in a body or in a material as a result of undergoing a sudden change in temperature.РІР‚Сњ When glass changes temperature rapidly it can undergo РІР‚Сљthermal shock.РІР‚Сњ In fact, thereРІР‚в„ўs no mention of РІР‚Сљshattering PyrexРІР‚Сњ on their website at all.

And, of course, this probably has to do with the fact that Pyrex isnРІР‚в„ўt going to advertise РІР‚Сљmay shatterРІР‚Сњ as a feature of their product. A reader wrote in because he set his Pyrex bowl on the stove top to reduce some broth, and the bowl promptly РІР‚Сљexploded.РІР‚Сњ It appears, through googling (and You Tubing), that a great many people do not realize that Pyrex bowls have a tendency to shatter violently and dramatically when placed on a stove top or otherwise heated/cooled rapidly.
