Maximum oven temperature for glass cookware
Is there a maximum safe temperature for cooking with a glass casserole dish in an oven?
Got some Dutch ovens on the bottom rack at 240C (450F) and wondering if I dare put a Pyrex dish on the top rack for half an hour...
Best Answer
A glass casserole dish, with a casserole in it, will be safe at any temperature your oven can reach.
As Ring mentioned, the issue is not absolute temperature, but fast changes in temperature, leading to a temperature differential and thermal stresses inside the dish. Your oven cannot heat the dish fast enough to cause a problem, and the wet food inside will prevent the dish from going far above 100C, meaning that cooling it down afterwards will also be safe.
If you're using the dish to roast dry ingredients, or otherwise won't have food keeping the dish cool, it'll still be safe, but afterwards make sure to let it cool a bit before running cold water over it.
And remember the first rule for avoiding burns: HOT GLASS LOOKS LIKE COLD GLASS. Pay attention and don't pick it up with your bare hands once it's out of the oven.

Quick Answer about "Maximum oven temperature for glass cookware"
Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans.How hot can oven be for glass pan?
Because glass is created at temperatures over 3,000 degrees Fahrenheit, it is very heat resistant. However, home ovens don't heat as evenly as industrial glass ovens, which causes breaking. For thin glass, this can start to happen at around 300 degrees Fahrenheit.Can Pyrex go in a 450 degree oven?
Pyrex is meant to be able to withstand higher temperatures. But everything has its limitations. 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 glass go in a 400 degree oven?
You can use a Pyrex oven-safe dish in a 400-degree oven. Before the first Pyrex pie plate was manufactured in 1916, home cooks didn't have access to glass bakeware that withstood both high and low temperatures without breaking.Oven Temperature Difference if Using a Metal or Glass Baking Pan : Desserts \u0026 Baking Tips

Answer 2
According to this page
The Pyrex heat capacity is truly impressive as the glass can withstand temperatures up to 932 degrees Fahrenheit
or 500°C
Beware, however
Pyrex will tolerate both hot and cold, but it can't do both at the same time. Pyrex can go from the freezer or fridge to the oven, but the trip needs to be a long one. Sudden changes in temperature can shatter any glass, including Pyrex
This Pyrex beaker has a temperature tolerance of 490°C, for instance.
