Pyrex pans are not meant to be used on burners
Some people have tried using Pyrex on burners, and it has resulted in their cookware exploding or cracking. One person tried melting butter on low heat, and their Pyrex dish exploded violently, sending glass shards flying. Another person's Pyrex dish cracked due to the heat of the burner. Even if a Pyrex dish is rated for -40 to +300 degrees Celsius, it is still risky to use it on a burner. It is important to follow the manufacturer's instructions and not use Pyrex on the stovetop to avoid potential danger.
The type of glass used in Pyrex also affects its suitability for use on burners. American Pyrex is made from soda-lime glass, which is sensitive to thermal shock. Even though it is tempered for kitchenware, it is not suitable for burners. European Pyrex is made from borosilicate glass, the same type of glass used in laboratory equipment. While it may be slightly more durable than American Pyrex, it still carries a significant risk of breaking on a burner.
There are some types of Pyrex that are meant to be used directly on the stove, such as Flameware and some modern Pyrex lines like Visions. These products are specifically designed for this purpose and can be used safely. However, it is important to always check the manufacturer's instructions before using any type of Pyrex on a burner to ensure it is safe to do so.
In conclusion, Pyrex pans are not meant to be used on burners. The glass can crack or explode due to thermal shock, and it is not a safe or effective way to conduct heat. There are other types of cookware that are better suited for stovetop use, and it is important to follow the manufacturer's instructions to ensure safe and proper use of Pyrex products.

American Pyrex is made from soda-lime glass, which is sensitive to thermal shock
Pyrex is a brand name for a range of glassware products used in kitchens and laboratories. It is important to note that not all Pyrex glassware is made from the same type of glass. American Pyrex products are made from soda-lime glass, while European Pyrex products are made from borosilicate glass.
Soda-lime glass is a type of glass that is commonly used in a variety of household items, such as drinking glasses and pickle jars. It is inexpensive to produce and can be treated to increase its durability. However, one of its major drawbacks is its sensitivity to thermal shock, which can cause it to shatter. Thermal shock occurs when there is a sudden or extreme change in temperature, such as when a hot liquid is poured into a cold glass. Soda-lime glass has a high coefficient of thermal expansion, which means that it expands significantly when heated and contracts when cooled. This makes it susceptible to breaking when exposed to extreme temperature changes.
On the other hand, borosilicate glass, which is used in European Pyrex products, is known for its resistance to thermal shock. It has a low coefficient of thermal expansion, which means that it does not undergo significant expansion or contraction when exposed to temperature changes. This makes it a safer option for use on burner stoves, as it can withstand higher temperatures and rapid cooling without shattering.
The difference in thermal shock resistance between American Pyrex (soda-lime glass) and European Pyrex (borosilicate glass) has been demonstrated through experiments and calculations. It has been found that soda-lime glass can only withstand a temperature difference of 54 Kelvin before shattering, while borosilicate glass can withstand a difference of 183 Kelvin. This means that using American Pyrex on a burner stove can be dangerous, as the glass can shatter violently and send sharp shards of glass flying across the room.
Therefore, it is strongly advised not to use American Pyrex pans directly on a burner stove due to the risk of thermal shock and shattering. While some older Pyrex products may have been made with borosilicate glass, which is more resistant to thermal shock, modern American Pyrex products are not safe for direct stove-top use. Always refer to the manufacturer's instructions and warnings to ensure safe use of your Pyrex products.
