Question: Why did my Pyrex dish explode?

Why did my Pyrex dish crack?

If there are any cracks in the outside of the dish, such as scratches or damage built up over many heat/cool cycles, this crack can travel through the dish and the tension in the surface can be released as a great big crack, and the plate will split.

At what temperature will Pyrex shatter?

Is Pyrex glassware susceptible to shattering? Shattering is relatively rare, but it can happen when glassware is exposed to sudden temperature changes (known as thermal shock), extremely high heat (over 425 degrees), or direct heat.

Can you put boiling water in Pyrex?
