While Pyrex glass is heat enhanced, through a thermal tempering process, to be durable and lasting, Pyrex glasses-- any glass items, for that matter-- can break if it's dropped, knocked versus a hard surface area, or struck with a tough utensilso handle your Pyrex glasses with care. If a piece of Pyrex glass wares does end up being cracked, cracked or scratched, don't utilize it, as its strength might be compromised and it might break or shatter (even long after a chip or crack appears).
Of course glassware gets incredibly hot in both standard and microwave ovens, so use protective pot-holders to handle heated glass-- do not ever touch the hot glass with your bare hands, or allow it to come into contact with your body. Keep hot glass well out of children's reach. Unequal heating, direct contact with heating elements, and abrupt temperature modifications (hot glassware being available in contact with something cool or wet, or cold glass wares being available in contact with something very hot) can trigger glass to shatter or break.
While the glass is designed for temperature levels usually used in baking, it can break when exposed to the direct heat component while the oven is pre-heating. Do not utilize Pyrex glasses on the stovetop (open flame, electric burner), under the broiler, in a toaster, or on an outdoor grill.
Before cooking items that may launch liquid (including fat, food juices, or moisture from frozen foods) in your Pyrex glassware, include a small amount of liquid to cover the bottom of the meal before you put it in the oven. Did you see this? serves to reduce any prospective unexpected temperature level change that might happen as the food launches liquid.
Including liquid to hot glass may compromise the item's strength, possibly leading to damage. Prevent positioning a hot Pyrex dish straight on a countertop or damp, cool or metal surface area. Position it on a dry cloth or potholder, or on a wooden trivet or cooling rack. Enable Pyrex to come to room temperature level before immersing in water or putting in the freezer, refrigerator, microwave or pre-heated oven.
Microwavable popcorn bags and browning wrappers are specially designed to focus heat in targeted spots, and may damage the glass. Do not heat empty or almost empty glass containers in the microware. When heating oil or butter in the microwave, heat just for the minimal time requireddon't overheat. Pyrex glasses plastic covers are BPA totally free.
