So if you're in a pinch and need to use glass or ceramic cookware for recipes that call for baking pans, reduce the baking temperature by about 25ºF. It's also important to note some glassware such as Pyrex can be prone to thermal shock, meaning rapid change in temperature could cause your bakeware to shatter.
Yes, Pyrex can go in the oven. You can use Pyrex glass cookware to cook, bake, warm or reheat food in pre-heated conventional and convection ovens.
Tips for Baking in Glass Instead of Metal
Keep in mind that glassware continues to retain the heat longer than metal pans, so you might want to also take the pan out of the oven slightly underdone and let the carryover heat continue to bake the dessert while it sits.
Bakes more quickly than metal: If you need to substitute a glass pan for a metal one, you will need to decrease the oven temperature by about 25 degrees to ensure that your baked good does not bake too quickly and burn.
That said, any pan is the right pan if it helps you put baked goods in the oven. The standard advice for baking in glass is to lower the oven temperature by 25°F from what the recipe calls for, and bake up to 10 minutes longer.
You can bake in oven-safe glass bowls, such as borosilicate or tempered-glass Pyrex dishes. Always follow the manufacturer's instructions and safety precautions.
Because glass is an insulator, rather than a conductor, it's slow to heat but, once hot, retains that heat for longer. This can result in uneven baking: By the time the interior is baked through, the exterior is often overcooked, dry, or dark.
It takes longer to heat than metal, which is a conductor. Because of this, loaves baked in glass pans may have different baking times than what a recipe calls for. An old rule (introduced by Pyrex itself) says to reduce the temperature 25 degrees lower than the recipe calls for if you're baking in glassware.
The 3-layer reinforced non-stick coating ensures cooking without ingredients attaching and ensures easy cleaning. Result: a range for Chef style cooking! Founded in 1915, the Pyrex® brand has always anticipated the latest trends in cookware and acknowledged every single need in kitchen households.
Pyrex, (trademark), a type of glass and glassware that is resistant to heat, chemicals, and electricity. It is used to make chemical apparatus, industrial equipment, including piping and thermometers, and ovenware.
The short answer to this question is “yes!” Regardless of age, Pyrex bakeware is safe to use in your oven (and microwave) as long as you avoid sudden and dramatic temperature changes.
Something to keep in mind is that you should reduce baking temperature by 25 degrees and check the food often as it may be ready up to ten minutes earlier if you are substituting a glass dish for a metal baking pan. This is because glass doesn't heat up as quickly as metal but will become very hot once heated up.
Pyrex: Brand name for cookware brand. pyrex: Lowercase indication of containers that should not be heated in the oven or microwave. These are most likely made of soda-lime glass. PYREX: Uppercase label on cookware that is made of borosilicate glass and can be heated in a microwave or oven.
As you can see in the photo, the slower transfer of heat to the batter means cakes baked in glass (or ceramic) will take longer to cook than those in metal (5 to 8 minutes longer, according to a test with yellow cake done by Cook's Illustrated).
Metal pans are better heat conductors than glass pans, meaning the food inside cooks more evenly. Most baking recipes for cakes, muffins, cupcakes, coffee cake, banana bread, and brownies call for metal bakeware.
Metal, Nonstick and Glass Pans
If you use dark nonstick or glass baking pans, follow the manufacturer's directions. You may need to reduce the baking temperature by 25F because these pans absorb heat, which causes cakes to bake and brown faster.
Glass pans, on the other hand, provide better heat distribution, leading to more evenly-baked brownies. Either can be a good option, depending on your preference.
The answer depends on the type of glass you are using. For that reason, you should always check the manufacturer's guidelines before putting glass in the oven. You may find that thin glass will break at around 150-200°C. However, thicker, oven-ready glassware may be able to withstand hotter temperatures.
Check to see if there is a marked "Oven-Safe" symbol underneath the piece. Glass bowls made of borosilicate or tempered glass and marked as oven-safe can go in the oven and withstand high temperatures. Those made of non-tempered glass may not be suitable with heat resistance and withstanding temperature changes.
The simple answer is NO. You shouldn't place any glass in the oven that is not labeled oven-safe. For more helpful tips, be sure to check out my posts, Can you put aluminum foil in the air fryer? and Can you freeze scones?
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.
