Is Pyrex safe? Can it randomly explode?

Pyrex is not designed for broiling and should not be used under a broiler. The intense heat can cause the glass to break.
Gradual Thawing:
If you have frozen food in Pyrex, thaw it gradually in the refrigerator before reheating in the oven. Avoid exposing frozen Pyrex directly to high heat.
Follow Manufacturer Guidelines:
Always follow the manufacturer’s guidelines for safe use and care of Pyrex products. These guidelines provide valuable information for ensuring the longevity and safety of your cookware.
Consider Alternatives:
If you have concerns about Pyrex, consider using borosilicate glass bakeware, which is more resistant to thermal shock. There are brands that still produce borosilicate glass cookware.
