What You'll Learn
Borosilicate glass pans are safe for frying
Frying in a glass pan may sound dangerous, but borosilicate glass pans are safe for frying. They are made of a type of glass that can withstand thermal shock and very high temperatures. This makes them suitable for use on a stovetop, even though some people may be hesitant to use glass cookware for frying.
The thermal properties of borosilicate glass also make it a good choice for frying. It is slow to heat up, but once it does, it has a huge thermal capacity and can take exceptionally high heat. This makes it suitable for frying, as you can heat the pan to a high temperature without worrying about it shattering.
In addition to its thermal properties, borosilicate glass is also non-reactive and will not leech into food like some other materials. This is a benefit if you have concerns about food contamination. However, it's important to note that not all glass cookware is created equal. While borosilicate glass and Pyroflam are suitable for high heat, Pyrex soda glass and regular glass cookware may not be as durable or heat-resistant.
Overall, borosilicate glass pans are a safe option for frying. They have excellent thermal properties and are resistant to thermal shock, making them suitable for use on a stovetop. Just be sure to choose a borosilicate glass pan that is specifically designed for frying, as some glass cookware may not have the ideal properties for this task.

Borosilicate glass pans can be preheated to 200°C/390°F
Borosilicate glass pans are a type of cookware that can be used for frying. They have a number of advantages over traditional metal pans. Firstly, they can be preheated to high temperatures of up to 200°C/390°F, which is higher than the typical temperature range of stovetops. This makes them ideal for searing meats and vegetables to lock in flavours and create a delicious crust. The high preheat temperature also means that borosilicate glass pans can be used for stir-frying, a cooking technique that requires intense heat to quickly cook ingredients while retaining their texture and flavour.
Another advantage of borosilicate glass pans is their slow heating property. This means that they take longer to heat up compared to other materials, but once they reach the desired temperature, they retain heat exceptionally well. This makes borosilicate glass pans ideal for cooking methods that require a steady and consistent temperature, such as simmering sauces or cooking delicate dishes that can easily overcook.
The thermal shock resistance of borosilicate glass is also noteworthy. It can withstand sudden changes in temperature without cracking or shattering, making it safer to use than regular glass cookware. This property also allows for convenient freezer-to-stovetop cooking, as you can store ingredients or prepared meals in the borosilicate glass pan and then directly heat them on the stovetop without worrying about the glass breaking.
Borosilicate glass pans offer a unique cooking experience with their ability to withstand high temperatures and resist thermal shock. They are a safe and versatile option for various cooking techniques, from frying to slow cooking. However, it is important to note that not all glass cookware is made of borosilicate glass, and the suitability of glass pans for frying is still debated by some.

Pyrex cookware is no longer made of borosilicate glass
The shift to soda-lime glass was justified by stating that it has higher mechanical strength than borosilicate glass, making it more resistant to physical damage when dropped. Additionally, soda-lime glass is cheaper to produce and more environmentally friendly. However, its lower thermal shock resistance can lead to potential breakage from heat stress if used contrary to recommendations. This has resulted in numerous reports of Pyrex glassware shattering, leading to safety concerns.
Despite the controversy, Pyrex cookware sold in the United States continues to use tempered soda-lime glass, while all French-made Pyrex glassware is still made from borosilicate glass. It is important to note that the logo style of Pyrex does not indicate the type of glass used to manufacture the bakeware.
While Pyrex may no longer use borosilicate glass in some of its products, there are still options available in the market for those who prefer borosilicate glass cookware. For example, Corning Vision offers a glass frying pan made of Pyroflam, which is superior to Pyrex soda or borosilicate glass and has excellent thermal properties.

Borosilicate glass pans are thermal shock-resistant
The composition of borosilicate glass includes silica (around 80%) and boron oxide (about 13%), which contribute to its low thermal expansion rate. It also contains smaller amounts of sodium oxide or potassium oxide and aluminium oxide. This combination of materials gives borosilicate glass superior durability, chemical resistance, and heat resistance compared to other types of glass.
The thermal shock resistance of borosilicate glass makes it a popular choice for cookware and drinkware. It can safely handle temperature changes up to 330 °F (170 °C), making it suitable for both hot and cold liquids. This is especially useful for drinkware, as it prevents cracking or breaking when switching between hot and cold drinks. Additionally, its heat resistance makes it ideal for stovetop cooking without the risk of shattering.
While borosilicate glass is more resistant to thermal shock, it is not completely immune to cracking or shattering. It can still break if subjected to rapid or uneven temperature variations. To prevent this, it is recommended to heat or cool borosilicate glassware at a similar rate across the entire piece, using an insulating trivet if necessary. This helps to minimise the expansion and contraction of the glass, reducing the risk of thermal shock.
Borosilicate glass pans offer a combination of durability, heat resistance, and thermal shock resistance. Their ability to handle rapid temperature changes makes them a safer and more durable option for cookware and drinkware compared to other types of glass. However, it is important to be mindful of sudden and extreme temperature changes to prevent the risk of cracking or shattering.

Borosilicate glass pans are safe for oven use
Borosilicate glass is known for its superior heat-resistant properties. It can withstand temperatures up to 200 degrees Celsius or 390 degrees Fahrenheit. This makes it suitable for prolonged oven use, even for recipes that require slow cooking or stewing for 2-3 hours.
However, it is important to be cautious when using any type of glass cookware in the oven. While borosilicate glass can handle high temperatures, rapid temperature changes can still cause thermal shock and potentially damage your cookware. Therefore, it is recommended to avoid extreme temperature fluctuations, such as transferring the dish directly from the oven into a sink of cold water.
Additionally, it is worth noting that glass is not as efficient of a heat conductor as metals like iron or aluminum. This means that it may take longer for your borosilicate glass pan to heat up compared to a metal pan. However, this can also be advantageous in certain situations, as it allows for slower, more even cooking, which is ideal for certain types of dishes.
In conclusion, borosilicate glass pans are safe for oven use and can be a great option for certain types of recipes. However, it is important to be mindful of the unique properties of glass cookware and adjust your cooking techniques accordingly to ensure the best results and maintain the durability of your pans.
