Pyrex Glass In Air Fryers: Safe Or Not?

Pyrex dishes are made of high-quality tempered glass, which is designed to be heat-resistant and durable, making it suitable for various cooking methods, including air frying. Pyrex glass is either borosilicate or soda-lime glass. Borosilicate glass is known for its excellent thermal resistance and can handle drastic temperature changes without breaking. Soda-lime glass is more susceptible to thermal shock and has a lower maximum temperature tolerance. Therefore, it is important to check the type of glass and the maximum temperature allowed for your specific Pyrex dish before using it in an air fryer.

Pyrex is safe in air fryers

Pyrex is safe to use in air fryers, but there are a few important things to keep in mind to ensure a safe cooking experience. Firstly, always check the manufacturer's instructions or packaging to understand the specific properties and temperature limits of your Pyrex dish. While Pyrex is generally heat-resistant, different products may have varying maximum temperature allowances, so it is crucial to refer to the manufacturer's guidelines.

Secondly, avoid sudden temperature changes when using Pyrex in an air fryer. Do not place frozen or extremely cold Pyrex dishes directly into a hot air fryer, as this can increase the risk of breakage due to thermal shock. Instead, allow the dish to come to room temperature before placing it in the air fryer, and always preheat the air fryer before use.

Thirdly, select a Pyrex dish that fits comfortably inside your air fryer basket or tray, allowing space for hot air to circulate 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 dish on a heat-resistant surface and allow it to cool before serving or cleaning.

By following these guidelines, you can safely use Pyrex in your air fryer and enjoy the benefits of its durability, strength, and ability to withstand high temperatures.

Pyrex can withstand extreme temperatures

Pyrex glass is made of borosilicate glass, which is a type of glass that does not easily react to heat. This means that Pyrex can withstand huge temperature changes, from −192°C to +500°C, or even −40°C to +300°C according to Pyrex themselves. However, if the temperature change is too sudden, Pyrex may crack due to thermal shock.

Pyrex has been designed to be oven-safe since its inception in 1915. These glass vessels, which range from casserole dishes to pie plates to loaf pans, are all safe for baking. However, it is important to follow one major rule when using Pyrex: avoid extreme temperature changes. Shifts from one extreme to the other can cause thermal shock to the dish, which can cause it to crack or shatter entirely.

For example, while a move from the fridge to a 350ºF oven likely won’t cause any damage to Pyrex dishes, it is recommended to avoid such extreme temperature changes. Instead, let your prepped food rest on the counter for 15 to 30 minutes before putting it in the oven. This is about the time it takes for the oven to preheat. In line with this, Pyrex recommends only placing their bakeware in an oven that is already heated.

Additionally, it is important to note that Pyrex should not be taken directly from the freezer and placed into a hot oven. This can cause the dish to shatter.

To avoid thermal shock, it is also important to not place a hot pan in cold water. Instead, let the pan rest until it is cool enough to touch before washing it. This tip applies to all types of cookware, not just Pyrex. Similarly, always place hot Pyrex dishes on a hot pad or trivet to protect the pan from thermal shock and your countertop from any damage.

Pyrex glass is a great option for use in air fryers as it can withstand extreme temperatures. However, it is important to ensure that the glass is oven-safe, tempered, and free of any cracks. Additionally, avoid using extremely high temperatures and sudden temperature shifts, as these can cause cracking.

Avoid high temperatures

Pyrex dishes are made of high-quality tempered glass, which is designed to be heat-resistant and durable. However, it's important to remember that not all glass is created equal, and some glassware may not be suitable for use in an air fryer.

To avoid potential issues when using glass in an air fryer, it is crucial to follow these guidelines:

• Avoid extremely high temperatures: Even oven-safe glass has its limits. Pyrex, for example, is typically safe up to temperatures of 425 degrees Fahrenheit, while some other glassware may only withstand up to 350 degrees Fahrenheit. Since air fryers can reach temperatures of 500 degrees Fahrenheit or more, always stay well within the safe range indicated for your specific glassware.
• Check the type of glass: Different types of glass have varying levels of heat resistance. Borosilicate glass, often used in Pyrex, is known for its excellent thermal resistance and ability to handle drastic temperature changes. On the other hand, soda-lime glass is more common but may not withstand extremely high temperatures. Always refer to the manufacturer's instructions to identify the type of glass and its temperature limits.
• Gradual temperature changes: Sudden shifts in temperature can cause glass to crack or shatter. Avoid placing chilled glass directly into a hot air fryer or vice versa. Instead, allow the glass to adjust to room temperature before placing it in the air fryer. You can also preheat the empty glass dish gradually as the air fryer preheats to prevent thermal shock.
• Inspect for damage: Before each use, carefully inspect your glassware for any cracks, scratches, or chips. Even small imperfections can compromise the integrity of the glass and increase the risk of breakage.
• Follow manufacturer's instructions: Each glassware manufacturer may have specific care and usage instructions. Familiarize yourself with these instructions to ensure safe use in your air fryer. Look for oven-safe symbols or temperature ranges indicated on the glassware as a guide.
• Avoid blocking airflow: Choose glassware that fits comfortably inside your air fryer, allowing adequate space for proper airflow. Glassware that is too large or too tightly packed can obstruct the hot air circulation, resulting in uneven cooking or longer cooking times.

Use tempered or oven-safe glass

Pyrex dishes are made of tempered glass, which is designed to be heat-resistant and durable, making it suitable for various cooking methods, including air frying. The glass used in Pyrex is either borosilicate or soda-lime glass. Borosilicate glass is known for its excellent thermal resistance and can handle drastic temperature changes without breaking. On the other hand, soda-lime glass is more common and offers good heat resistance.

When using tempered glass in an air fryer, it is important to check the maximum temperature allowed for your specific dish. Although tempered glass is generally heat-resistant, different products may have varying temperature limits. Refer to the manufacturer's instructions or packaging to determine the maximum high temperatures your dish can safely withstand. Additionally, avoid placing frozen or extremely cold dishes directly into a hot air fryer, as this sudden temperature change can increase the risk of breakage.

To identify if your glass dish is oven-safe, read the manufacturer's stamp or label. Oven-safe glass dishes typically withstand a maximum temperature of 350°F to 450°F. You can also verify this by placing an empty dish in the air fryer several times. As oven-safe bakeware was designed for traditional ovens, use caution when placing it in an air fryer.

Before using tempered glass in an air fryer, inspect the dish for any small cracks, scratches, uneven surfaces, or colour changes. If you notice any structural weaknesses, do not use the dish in the air fryer. Additionally, ensure that the dish fits comfortably inside the air fryer basket or tray, allowing space for hot air to circulate and cook the food evenly.

Don't block the airflow

When using glass in an air fryer, it's important to ensure that the airflow is not blocked. The size of your glass cooking vessel matters—it should fit in with ease and allow for proper airflow around the food. If the circulating air is blocked, your food may come out soggy and unevenly cooked. Crispy foods, in particular, require good airflow to achieve that desired crispiness.

To ensure proper airflow, choose a glass cooking vessel that is not too big for your air fryer. It should fit comfortably inside with enough space for air to circulate. You can also use a wire rack or basket inside your air fryer, which helps to elevate the food and improve airflow.

Additionally, avoid placing items on top of the air fryer that may block the vents or airflow. This includes not covering the air fryer with a lid or placing objects on top that may restrict airflow.

By following these guidelines, you can ensure that your air fryer functions optimally and that your food cooks evenly and efficiently.
