Did You Know?
1. Pyrex is safe to use in ovens at temperatures up to 450 degrees Fahrenheit (232 degrees Celsius). However, it is important to note that sudden temperature changes can cause the glass to shatter.
2. The name “Pyrex” actually comes from combining the words “pyro” (meaning fire) and “ex” (meaning outside). This name was chosen to emphasize the glassware’s ability to withstand high temperatures.
3. In the early 1900s, Corning Glass Works (the company behind Pyrex) developed a special type of glass that could be used in both laboratories and kitchens. This innovation made Pyrex cookware popular among home cooks and scientists alike.
4. While Pyrex is known for its ability to withstand high heat, it can also tolerate very low temperatures. In fact, you can safely place Pyrex in the freezer to chill or store food.
5. Pyrex glassware is made using a special type of glass called borosilicate. This type of glass contains boron, which gives Pyrex its excellent thermal properties, making it more resistant to thermal stress than regular glass.
Recommended Temperature Range For Pyrex In The Oven
Pyrex glass products have long been a staple in kitchens around the world, known for their durability and versatility. According to the manufacturer, Pyrex glassware is oven safe to at least 500°F (260°C). However, it is recommended to use temperatures up to 425°F (218°C) on the safe side.
When using Pyrex in the oven, it’s essential to keep in mind that rapid temperature changes should be avoided. For instance, moving cold Pyrex directly from the refrigerator to the hot oven can cause the glass to shatter. Similarly, pouring cold water into a hot Pyrex dish or exposing it to sudden temperature changes while preheating the oven can also have detrimental effects.
It’s worth noting that vintage Pyrex may have different temperature limitations. While it can still be used in the oven, it is advisable not to exceed temperatures of 425°F (218°C). Aging can cause cracking or chipping of the glass, making it unsuitable for oven use. To ensure even baking and to prevent quick browning of the sides and bottom, decrease the oven temperature by 25°F (15°C) below what the recipe suggests when using vintage Pyrex.
- Pyrex glassware is oven safe to at least 500°F (260°C)
- Recommended to use temperatures up to 425°F (218°C)
- Avoid rapid temperature changes
- Be cautious when moving cold Pyrex from the refrigerator to the hot oven
- Do not pour cold water into a hot Pyrex dish
- Vintage Pyrex may have limitations, advisable to not exceed 425°F (218°C)
- Decrease oven temperature by 25°F (15°C) when using vintage Pyrex.
Avoiding Rapid Temperature Changes To Prevent Shattering
One of the most crucial aspects of using Pyrex glassware in the oven is avoiding rapid temperature changes. Although Pyrex is designed to withstand high oven temperatures, subjecting it to sudden shifts can cause it to shatter.
To prevent this, it is important not to move Pyrex directly from the refrigerator or freezer into the oven, as the extreme temperature difference can cause thermal shock. Similarly, pouring cold water into a hot Pyrex dish can have the same effect.
Additionally, it is essential not to place cold Pyrex dishes on wet or cool surfaces, as this can create uneven heating and increase the risk of shattering. Pyrex should also never be used on a stovetop over an open flame, electric burner, or on a grill. These direct heat sources can cause the glass to fracture.
Limitations on Oven Use for Pyrex Glassware
Although Pyrex glassware is highly durable, it has certain limitations when it comes to oven use. It is important to note that Pyrex should not be used in a toaster oven, under the broiler, or on a grill. These high-intensity heat sources can cause Pyrex to break or shatter due to the extreme temperatures.
Furthermore, Pyrex glassware should not be used directly on the stovetop, as the direct heat from burners can cause damage to the glass. It’s crucial to follow these limitations to ensure the longevity and safety of your Pyrex glassware.
Heat Resistance of Borosilicate Pyrex Vs. Tempered-Glass Pyrex
When considering the heat resistance of Pyrex glassware, it’s important to distinguish between borosilicate Pyrex and tempered-glass Pyrex.
- Borosilicate Pyrex is more heat resistant than tempered-glass Pyrex and can withstand a temperature change of up to 396°F (220°C).
- This distinction is vital as it can help determine the best use and application for each type of Pyrex glassware.
- Borosilicate Pyrex is often preferred for more high-temperature applications.
-
Tempered-glass Pyrex is suitable for everyday oven use within the recommended temperature range of up to 425°F (218°C).

Precautions and Guidelines for Safe Oven Use of Pyrex
To ensure the safe usage of Pyrex glassware in the oven, there are a few precautions and guidelines to keep in mind.
First and foremost, it is essential to use branded Pyrex glass with the logo. Counterfeit products or glassware without the proper branding may not meet the same safety standards.
Always inspect Pyrex glassware for any chips or cracks before using it in the oven. Damaged glassware may be more prone to shattering under high temperatures.
When using Pyrex, be sure to preheat the oven before placing the glassware inside. Heating an empty Pyrex dish can compromise its structural integrity and potentially cause it to break.
Furthermore, when cooking items that may release liquids, it is recommended to add a small amount of liquid to cover the bottom of the dish before placing it in the oven. This helps to prevent thermal shock and maintains the integrity of the glass.
Lastly, it’s important to allow Pyrex to come to room temperature before subjecting it to a significant change in temperature. This is especially crucial when transferring Pyrex from the refrigerator or freezer to the oven.
By following the recommended temperature range, avoiding rapid temperature changes, and adhering to the precautions and guidelines provided, you can safely utilize Pyrex glassware in the oven.
