Pyrex Glassware: Safe For Air Fryers?

Air fryers are a common kitchen appliance, but many people are unsure about whether it is safe to use glass Pyrex dishes in them. Pyrex is a well-known brand of tempered glass dishes that are designed to be heat-resistant and durable. The short answer is yes, you can use glass Pyrex in an air fryer, but there are some important safety precautions to keep in mind. Firstly, it is crucial to check the maximum temperature allowed for your specific Pyrex dish, as different products may have varying temperature limits. Additionally, it is recommended to avoid sudden temperature changes, as this can cause glass to crack or shatter. Other precautions include ensuring the dish is oven-safe, allowing space for airflow, and handling the dish with care when removing it from the air fryer.

Secondly, it is crucial to check the maximum temperature allowed for your specific Pyrex dish. Different Pyrex products may have varying temperature limits, so referring to the manufacturer's instructions or packaging is essential. Pyrex dishes are typically safe at temperatures up to 425 degrees Fahrenheit, but some can only withstand around 350 degrees Fahrenheit. Since air fryers can quickly reach temperatures of 500 degrees Fahrenheit, staying well within the safe temperature range for your dish is crucial.

Thirdly, it is recommended to preheat your air fryer before placing the Pyrex dish inside. Preheating helps evenly distribute heat and ensures proper cooking. However, avoid placing frozen or extremely cold Pyrex dishes directly into a hot air fryer, as this sudden temperature change can increase the risk of breakage. Instead, allow the dish to come to room temperature before placing it in the air fryer.

Additionally, when selecting a Pyrex dish for air frying, choose a size and shape that fits comfortably inside your air fryer basket or tray, allowing space for hot air to circulate around the dish and cook the food evenly. Avoid overcrowding or stacking dishes, as this can hinder airflow and result in uneven cooking.

Finally, always handle Pyrex dishes with oven mitts or heat-resistant gloves when removing them from the air fryer, as they will be hot. Place the hot dish on a heat-resistant surface and allow it to cool before serving or cleaning.

Pyrex is made from borosilicate glass

Pyrex is a brand name for a type of borosilicate glass developed by Corning Glass Works in 1915. Borosilicate glass is made from a mixture of silica, boron, and other elements. It is known for its excellent chemical resistance, low thermal expansion, and high thermal stability. Pyrex, in particular, is known for its excellent thermal stability and resistance to thermal shock.

Pyrex products were made of borosilicate glass until the 1950s when the brand switched to manufacturing products with tempered soda lime instead. Today, every piece of Pyrex bakeware made in the U.S. uses tempered soda lime, which is better for the environment, requires less energy to produce, and is more easily recyclable.

Despite this change, borosilicate glass remains a superior option for use in the kitchen and laboratory due to its ability to withstand extreme temperature changes. This is because borosilicate glass includes boron trioxide, which has a low thermal expansion, meaning it won't break when exposed to major temperature shifts.

When using Pyrex in an air fryer, it is important to keep in mind that not all glass is created equal. Pyrex is safe at temperatures up to 425 degrees Fahrenheit, but some glass can only withstand temperatures up to 350 degrees Fahrenheit. Therefore, it is crucial to check the bottom of your cookware for the exact temperature ranges and stay well within the safe ranges.

In summary, Pyrex is made from borosilicate glass, a type of glass known for its excellent chemical resistance, low thermal expansion, and high thermal stability. While Pyrex is no longer made from borosilicate glass, it remains a trusted brand for kitchenware and laboratory glassware due to its durability and ability to withstand high temperatures.

Pyrex can withstand extreme temperatures

Pyrex glassware is made of borosilicate glass, which is highly resistant to extreme temperatures. It can withstand temperatures ranging from -192°C to +500°C, or -377.6°F to +932°F, making it ideal for laboratory glassware that will be directly heated. This is because borosilicate glass has a higher proportion of silicone dioxide than soda-lime glass, which makes it less likely to expand when heated and, therefore, less likely to break.

Pyrex glass can be used in air fryers, but it is important to note that not all glass is created equal. Older Pyrex glassware, for example, may be stamped for oven use but not stovetop or broiler use. While Pyrex is generally safe for temperatures up to 425°F, some glass may only withstand around 350°F. Since some air fryers can quickly reach temperatures of 500°F, it is crucial to check the bottom of your cookware for the exact temperature range and stay within the safe limits.

Additionally, Pyrex glass can crack due to thermal shock if the temperature changes are too sudden. Therefore, it is recommended to avoid putting chilled glass directly into a hot environment or vice versa. To prevent thermal shock, you can preheat the empty glass dish gradually as the air fryer preheats. This not only warms up the glass but also allows you to determine whether your glass can withstand the heat before adding food.

By following these guidelines and using oven-safe, tempered glass, you can safely use Pyrex in an air fryer to make your favourite dishes.

Avoid sudden temperature changes with Pyrex

Pyrex glassware is safe to use in an air fryer, but it's important to take precautions to avoid sudden temperature changes, which can cause cracking or even shattering. Here are some tips to avoid sudden temperature changes when using Pyrex in an air fryer:

• Avoid placing chilled or frozen Pyrex directly into a hot air fryer. Instead, allow the glass dish to come to room temperature before placing it in the air fryer.
• Preheat the air fryer gradually with the empty Pyrex dish inside. This helps to warm up the glass and ensures it can withstand the heat before adding food.
• Familiarise yourself with the Pyrex care instructions before using it in the air fryer. Check for any structural weaknesses, such as small cracks or scratches, as these can increase the risk of breakage.
• Avoid taking the Pyrex dish directly from the freezer to the oven or vice versa. Extreme temperature changes can cause thermal shock, which can damage the glass.
• Always check the maximum temperature allowed for your specific Pyrex dish. Different Pyrex products have varying temperature limits, so refer to the manufacturer's instructions to stay within the safe range.
• Avoid rapid temperature changes when cooking. For example, don't add cold liquid to hot glassware or vice versa.
• Handle Pyrex dishes with care when removing them from the air fryer. Use oven mitts or heat-resistant gloves, as the dishes will be hot. Place the hot dish on a heat-resistant surface and allow it to cool down before serving or cleaning.

Pyrex is oven-safe

However, it is crucial to avoid extreme temperature changes when using Pyrex. Shifts between extremes can cause thermal shock, resulting in cracking or shattering of the glass. Therefore, it is recommended to let dishes rest at room temperature for 15 to 30 minutes before transferring them to the oven. Additionally, Pyrex should only be placed in an oven that has already been preheated to avoid direct exposure to the heating element during the preheating process.

It is also important to note that Pyrex should not be used on stovetops or placed directly from the freezer into a hot oven. Vintage Pyrex is generally safe to use, but it is advised to avoid using any dishes with chips or cracks as they can release more glass chips or cause the dish to crack entirely.

To summarise, Pyrex is oven-safe, but users should be cautious of temperature changes and always follow safety guidelines to ensure a safe and enjoyable cooking experience.
