What Causes Pyrex Dishes to Shatter After Removing From the Oven?
Pyrex brand glass cookware and bakeware became famous for being safe to take from a refrigerator or freezer and place directly into a hot oven without fear of breakage. However, in recent years, Pyrex containers started exploding under these circumstances. Does this Spark an idea?
-
Glass Breakage
-
Glass breaks or explodes when it experiences drastic and quick temperature changes, a process called thermal shock. Since it is a brittle substance, sudden atmospheric variances cause it to disintegrate when it does not have time to slowly adjust to temperature variations.
Pyrex Composition
-
When Pyrex first came on the market, it was made from borosilicate glass, which is highly resistant to the effects of drastic temperature fluctuations. Pyrex dishes are now made of soda-lime glass, which is less expensive to manufacture but not very resistant to temperature variances.
-
Coping Suggestions
-
Until a higher quality of glass is used in the Pyrex manufacturing process, consumers should treat the cookware like regular glass. Bring chilled dishes to room temperature before placing them into a hot oven and do not set hot dishes on the tops of cold stove or counter tops. Never put a hot glass dish into water of any temperature.
