Pyrex® glassware is designed to be as versatile as it is long lasting. You can use it to prepare, store, cook, bake, warm or reheat food—in pre-heated conventional and convection ovens, or in microwaves.
The Pyrex® glass can be safely used in the oven at 425°F (218°C). However, borosilicate Pyrex can be heated up to 500°F (260°C), according to some sources, up to 914°F (490°C).
A: Pyrex is suitable for use from -192°C to +500°C. This makes it an ideal choice for lab glassware which will be directly heated. Pyrex is borosilicate glass which makes it highly temperature resistant. Soda-Lime glass is less suitable for direct heating, so choose Pyrex where possible if you will be applying heat.

The answer depends on the type of glass you are using. For that reason, you should always check the manufacturer's guidelines before putting glass in the oven. You may find that thin glass will break at around 150-200°C. However, thicker, oven-ready glassware may be able to withstand hotter temperatures.
Most glass that is oven safe can withstand temperatures up to 600° Fahrenheit, so it is safe to use it in the oven as long as you keep the heat lower than that.
Avoid high oven temperatures: don't expose the glass to oven temperatures above 350°F (177°C). After baking with glassware, let your dish cool down to room temperature before cleaning it with water. Washing a hot glass dish with cold water can cause the dish to break.
Preheat the oven to 375°F. Bring a kettle of water to a boil. Place the lasagna in a 9"x13" pyrex or oven-safe dish, then cover the lasagna in the boiling water until it's fully immersed.
A: It means that you can put it directly into a preheated oven (meaning a sudden big temperature change for the glass) without the glass breaking.
Big-p PYREX is made of borosilicate glass, which is much more heat-resistant and durable than other kinds of glass. That makes this a good material for making cookware and microwaveable containers, plus you can feel safe adding hot liquids to measuring cups made from it or using those measuring cups in the microwave.
Several contributing factors can cause tempered glass to shatter, but the most common culprits are surface damage, extreme thermal stress, and manufacturing flaws; often, it's a combination of these things.
Pyrex remains just as robust, versatile, and reliable today. However, as with all glass, it doesn't conduct heat well or uniformly. This makes it good for keeping stock warm or baking a lasagna, but not at all suited to baking anything that needs a crisp bottom, such as a pizza or most pies.
The short answer to this question is “yes!” Pyrex bakeware (both old and new) is safe to use in your oven – and microwave – as long as you avoid dramatic, sudden temperature changes. But as with almost any type of glass item, there are few finer details worth knowing in order to use it safely and effectively.
The standard advice for baking in glass is to lower the oven temperature by 25°F from what the recipe calls for, and bake up to 10 minutes longer. The hard edges we see here are more pronounced in high-sugar, high-fat recipes; your casserole or bread pudding are less likely to be adversely affected.
Make sure the glass you put in the oven is labeled “oven-safe.” It is labeled as such you can rest assured that it is tempered glass. Avoid High Heat: Most glass should not be heated above 350 F. Some types of glass can be heated higher, so be sure to check your glassware for the recommended heat range.
Pyrex also recommends preheating your oven before placing the glass dish inside so that it isn't exposed to a big change in temperature and to always let Pyrex come to room temperature before placing it in an oven, freezer, or refrigerator.
Glass is a poor thermal conductor and rapid changes in temperature (roughly 60°F and greater) may create stress fractures in the glass that may eventually crack. When heated, thin glass begins to crack and typically breaks at 302–392°F.
Tempered glass is stamped with an identifier, which can be found in the corner of the sheet of glass. The identifier will show the manufacturer name and the CPSC (Consumer Product Safety Commission) standards, e.g. “CPSC 16 CFR 1201 CAT II”. This proves if the glass is tempered or not.
For most kinds of glass, this annealing temperature is in the range of 454–482 °C (850–900 °F), and is the so-called stress-relief point or annealing point of the glass.
The softening point (temperature at which viscosity is approximately 107.6 poise) of type 7740 Pyrex is 820 °C (1,510 °F).
Don't Use Chipped or Broken Pyrex
It may be tempting to continue to use a Pyrex dish that has a small chip or crack – but don't do this! What is this? Any broken Pyrex is compromised and can shatter or explode in the microwave. You will need to replace the dish or look into pursuing any warranties.
As soon as possible, and no more than two minutes after removing the Pyrex glassware from the microwave or oven, carefully put the plastic lid directly on the hot dish.
