Pyrex is generally oven safe to at least 500 degrees Fahrenheit. Unless it is very old or very used. I've seen Pyrex dishes go into 600 degree pizza ovens, over open flames on a range, even into coals in a campfire without issue.
The added boron allows Pyrex to handle heat much better than typical glass, so Pyrex is commonly found in kitchens, laboratories, and in use with aquarium heaters (as the heaters are, necessarily, submerged in much cooler water). But in 1998, Corning, the company which made Pyrex, sold the brand to World Kitchen LLC.
