Glass In Air Fryers: Safe Or Not?

Air fryers are becoming increasingly popular, and for good reason. They can deliver quick, perfectly cooked meals in a matter of minutes. With this surge in popularity, many people are left wondering if they can put glass in an air fryer. The short answer is yes, but there are some important precautions to be aware of. Firstly, it is crucial to use oven-safe, tempered glass that is free of any cracks or scratches. Secondly, avoid high temperatures and sudden temperature shifts as these can cause cracking or shattering. Finally, ensure the glassware does not block the airflow in the air fryer, as this will impact the cooking process. By following these guidelines, you can safely use glass in your air fryer.

Glass is safe and non-toxic

Glass is a safe and non-toxic option for cooking in an air fryer. It is a non-reactive material, meaning it won't alter the flavour of your food. This is especially important when cooking highly acidic or alkaline ingredients, such as citrus marinades or tomato sauces, as these can react with other materials like aluminium or copper. Glass is also a great option for storing food in the refrigerator, as it is safe and chemical-free, even when reheated multiple times.

When using glass in an air fryer, it is important to use tempered or oven-safe glass that is heat-resistant and free of any cracks or scratches. Borosilicate glass, such as the well-known brand Pyrex, is a great option for air fryer cooking as it is super durable. It is important to avoid using soda-lime glass, as this type of glass cannot withstand high temperatures and is susceptible to thermal shock. Always check the manufacturer's label or stamp to verify that your glassware is oven-safe.

To prevent accidents, avoid putting glass in an air fryer at extremely high temperatures or subjecting it to sudden temperature changes. Air fryers can reach temperatures of up to 500 degrees F, but oven-safe glass typically has a maximum temperature of 350-450 degrees F. By checking the bottom of your glassware for the temperature range, you can ensure that you stay within the safe range for your particular glassware.

Another important consideration when using glass in an air fryer is to ensure that it does not block the airflow. Air fryers work by circulating hot air, so if the airflow is blocked, your food may not cook properly or may cook unevenly. Choose glassware that is the appropriate size and shape for your air fryer, taking into account the space needed for proper airflow.

Glass can withstand high temperatures

Glass Types

Standard window glass will break when it reaches approximately 250°F (121°C). Tempered glass can withstand temperatures up to 500°F (260°C). Fire-rated glass can survive heat in excess of 1600°F (871°C).

Pyrex, made from borosilicate glass, is suitable for temperatures from -192°C to +500°C. However, Pyrex can still crack due to thermal shock if the change in temperature is too sudden.

Using Glass in an Air Fryer

When using glass in an air fryer, it is important to use tempered or oven-safe glassware. Oven-safe glass can usually withstand temperatures of 350-450°F (176-232°C). Always check the manufacturer's stamp or label to be sure. If the stamp has faded, you can check the manufacturer's website or social media accounts.

Before using glass in an air fryer, it is also important to check for any structural weaknesses. Hold the glass up to the light and look for small cracks, scratches, uneven surfaces, or colour changes. If you see any of these, do not use the glass in the air fryer.

Another important consideration is size and shape. The glassware should not take up more than half of the basket space, as this will affect the airflow and prevent the food from cooking properly.

Benefits of Using Glass in an Air Fryer

Glass has several advantages over other materials when it comes to cooking. It is non-reactive, so it won't alter the flavour of your food. It also has great heat retention, which helps to achieve more efficient, even cooking temperatures. Glass is also non-toxic and can be used for storage in the refrigerator.

Glass is durable

Glass is a highly durable material with a wide range of applications, from windows and bottles to electronics and fibre optics. Its strength and durability are determined by its chemical composition and molecular structure.

Glass is primarily made up of silicon dioxide (SiO2). However, other substances can be added to modify its properties and make it suitable for specific purposes. For example, borosilicate glass contains boron oxide (B2O3), which gives it added strength and durability, making it ideal for withstanding extreme temperatures and pressure.

The molecular structure of glass is unique, with its atoms arranged in a disordered, jumbled manner. This provides glass with interesting properties, such as the ability to withstand stress. When stress is applied, the molecules have space to move and disperse, preventing breakage at certain points. This is why glass often cracks but doesn't always shatter completely.

Additionally, glass is strengthened through techniques such as tempering and laminating. Tempering involves heating the glass to extremely high temperatures and then quickly cooling it down, resulting in improved impact and thermal stress resistance. Laminating, on the other hand, involves sandwiching a layer of polymer between two glass panels, creating a stronger, safer structure.

The durability of glass is further enhanced by its environmental sustainability. Glass is made from natural, sustainably sourced materials such as sand, soda ash, limestone, and recycled glass. It is also infinitely recyclable, reusable, and refillable, reducing waste and conserving natural resources.

In the context of air fryers, thick, tempered glass is recommended as it is durable and heat-resistant. Glass is a suitable material for air fryers due to its non-reactivity, heat retention, and clear visibility, allowing for efficient and even cooking without altering the flavour of the food.
