Why did my glass pan explode?

Why did my glass casserole dish explode?

Pyrex is meant to be able to withstand higher temperatures. Pyrex can be used safely inside an oven that is less than 450 degrees F. Whether or not it’s inside a conventional oven or a convection oven, this glassware will be safe to use so long as that temperature isn’t exceeded.
Can I freeze lasagna in a Pyrex dish?

Can glass explode in the oven?
Even being oven safe won’t protect a glass that is on the verge of breakage, and it will likely shatter once exposed to high heat. Another thing to keep in mind when using glass is that even oven safe glass doesn’t do well with sudden temperature changes, as this can cause a glass break.
