General Handling & Storage:
* Avoid Sudden Temperature Changes: Don't put hot Pyrex directly into cold water or vice versa. This rapid temperature shift can cause the glass to crack. Let it cool down gradually or warm up slowly before introducing it to a drastically different temperature.
* Use Oven Mitts: Always use oven mitts or pot holders when handling hot Pyrex, even if it's just out of the oven.
* Proper Storage: Store Pyrex bowls in a safe, secure location where they won't be easily knocked over or dropped. Avoid stacking them too high, as this can put pressure on the bottom bowl.
* Don't Use on a Hot Stovetop: Pyrex is not meant for direct heat on a stovetop. It can melt or crack.
Specific Scenarios:
* Microwave: Use a microwave-safe Pyrex bowl and always follow the manufacturer's instructions. Don't overheat the food or leave it in the microwave for too long.
* Freezing: Pyrex is freezer-safe, but avoid filling the bowl completely, as the contents expand when frozen. Also, avoid placing the bowl directly on a freezing surface.
* Cleaning: Hand-washing is generally recommended, but if you use the dishwasher, choose a delicate cycle and avoid harsh detergents.
* Scratches: Minimize scratches by using soft sponges and avoiding abrasive scrubbers.
Signs of Weakness:
* Cracks: If you see any cracks, even small ones, discard the bowl. Don't use a cracked Pyrex bowl as it can shatter unexpectedly.
* Chips: Chips can also weaken the bowl and should be watched for.
Alternatives:
* Consider Other Materials: If you're concerned about breakage, consider alternatives like plastic or ceramic bowls.
Remember:
* Even with careful handling, any glass product can break.
* Always exercise caution and prioritize safety.
Following these tips will help you enjoy your Pyrex bowls for years to come.
