What You'll Learn
Glass pans can shatter on the stove
The type of glass used in cookware also determines its susceptibility to shattering. Most glass kitchenware is made of soda-lime glass, which is not suitable for direct heat. However, borosilicate and pyroceram glass cookware can withstand extremely high temperatures and are designed to resist thermal shock. These types of glass can be safely used on the stove without shattering.
To prevent glass pans from shattering on the stove, it is crucial to choose the right type of glass cookware. Glass cookware with a bottom made from a magnetic metal can be used on induction stovetops, as they require electromagnetic energy transfer for heating. Additionally, using a simmer plate or heat diffuser underneath the glass pan can help distribute heat more evenly and reduce the risk of thermal shock.
Despite these precautions, there is still a possibility of glass pans shattering on the stove due to the intense heat. Glass cookware that is not specifically designed for stovetop use should be avoided. Instead, it is recommended to use alternative materials like stainless steel or well-seasoned cast iron for cooking, especially when dealing with acidic foods. These materials are safer options that can withstand higher temperatures and direct heat without the risk of shattering.
While glass pans offer aesthetic appeal and dishwasher-safe convenience, their limitations in heat conduction and susceptibility to thermal shock make them less ideal for stovetop use. To ensure safety and avoid shattered glass, it is generally recommended to opt for alternative cookware materials specifically designed for stovetops.

Borosilicate glass can withstand heat
Glass pans or kitchenware are typically made from soda-lime glass, which has a low heat resistance and will shatter if exposed to extreme temperature changes. However, some glass pans may be made from borosilicate glass, which is a special type of glass that can withstand high temperatures.
Borosilicate glass is made by melting silica sand with boron trioxide, which limits the material's ability to expand when exposed to heat. This makes it ideal for creating heat-resistant glassware, containers, and scientific tools. It is commonly used in laboratories for test tubes, beakers, and stirring rods due to its ability to withstand high temperatures without melting or cracking.
The addition of boron trioxide to the silica sand mixture significantly increases the heat resistance of borosilicate glass compared to soda-lime glass. While soda-lime glass can only withstand a temperature change of about 100 °F (40 °C), borosilicate glass can handle a temperature differential of about 330 °F (170 °C) before fracturing. This makes borosilicate glass suitable for extreme temperature changes, such as taking it from the freezer to an oven rack without cracking.
Borosilicate glass is also chemically resistant, preventing unwanted materials from leaching into the glass or vice versa. This makes it safe for storing hot liquids and even nuclear waste. Its durability and stability ensure that it won't chip, crack, or release toxins when knocked or exposed to heat.
While borosilicate glass is more expensive and fragile than soda-lime glass, it is a popular choice for chefs and scientists due to its superior heat resistance and durability. However, it is important to note that not all glass pans or kitchenware are made from borosilicate glass, and placing a soda-lime glass pan on a stove may result in shattering or cracking.

Cast iron pans are safe on glass stoves
Glass stovetops are susceptible to thermal shock and surface scratches from heavy cookware. Cast iron is heavy, rugged, and heats slowly, so you need to be careful when using it on a glass stove.
Cast iron pans are safe to use on a glass stovetop, but caution is required to avoid damaging the glass. Cast iron is one of the most common types of cookware in American kitchens due to its versatility, sturdiness, and longevity. It is also a good heat conductor, heating up faster and more evenly than standard Teflon frypans.
Cast iron cookware was originally intended for use over open flames, but glass-topped electric and induction cooktops are becoming increasingly popular. Cast iron can be used on a glass stove if you take a few precautions. Firstly, avoid sliding or dragging the cast iron on the surface, as this can cause scratches and damage. Instead, lift and gently place the cookware.
Additionally, ensure that the bottom of the cast iron pan is clean, dry, and free of any residue before use, as burned-on food clinging to the bottom can scratch the glass surface over time. It is also important to clean spills promptly and maintain a clean cooktop to avoid stains and damage.
Cast iron is heavy, so it is important to be gentle when placing it on the glass stove to avoid cracking the surface. Overall, with proper precautions and maintenance, cast iron pans can be safely used on a glass stovetop without causing damage to the stove or the pan itself.

Avoid thermal shock on glass stoves
Glass pans or cookware can cause thermal shock on glass stoves, leading to cracking and breaking. To avoid this, it is recommended to use trivets or heat-resistant pads under pans to protect the glass stove surface.
Glass pans or cookware should not be placed directly on a glass stove, as the heat transfer can cause thermal shock, leading to cracking or even shattering of the glass. This is because most glass kitchenware is made of soda-lime glass, which cannot withstand rapid temperature changes.
However, some glass pans or cookware may be made of borosilicate glass, which has a low thermal expansion coefficient, making it more resistant to thermal shock. These types of glass pans can be used on stovetops, but it is essential to check the manufacturer's guidelines first. Improper use may still cause damage or reduce the product's lifespan.
To avoid thermal shock on glass stoves, it is recommended to follow these guidelines:
- Use trivets or heat-resistant pads: Place trivets or heat-resistant pads made of materials like silicone or cast iron under glass pans to protect the glass stove surface from direct heat.
- Avoid sudden temperature changes: When using glass pans on a glass stove, avoid extreme temperature changes. Allow the glass pan to cool down to room temperature before placing it on the glass stove, and vice versa when removing it from the heat.
