How to test temperature in 1960s electric GE Americana range?

[mgresh56]

Hi! (I'm not sure I'm doing this posting thing correctly!) I have a 1960s GE Americana electric range. Yesterday, I cooked a pork roll in its upper oven set to 425...in a Pyrex baking dish lined with aluminum foil. (I'm also no cook, really, so if there's anything I shouldn't have done in the actual basic baking process feel free to call me a bozo.) The Pyrex broke in half at some point during the baking. Now, admittedly, it's an *old* very scratched up dish, so I'm not sure if the dish's integrity played any part in it, but I'm wondering if the oven itself is running wayyyy higher than 425? How do I and what instrument would I use to gauge whether the oven is at the temperature I've chosen? Thank you so much for any advice!!!

If you're glass baking dish was scratched, especially deeply, that would make it much more likely to break. This is particularly true if it is the newer soda-lime glass, rather than the older borosilicate glass. The aluminum foil probably didn't help matters, either.
