Hot pans can be placed on a glass cooktop
When using a glass cooktop, it is important to be cautious with cast iron cookware. While cast iron can be used on a glass cooktop, it should be handled with care to avoid scratches and cracks on the glass surface. Always ensure the bottom of the pan is smooth and clean before placing it on the cooktop, and avoid sliding or dropping the pan onto the glass as this can cause damage.
It is also important to be mindful of thermal shock when using a glass cooktop. Rapid temperature changes can cause the glass to crack, so it is recommended to use trivets or heat-resistant pads underneath hot pans to protect the surface. Regularly inspect the cooktop for any hairline cracks or chips, as these can worsen with heat.
Additionally, it is important to note that not all types of cookware are compatible with glass cooktops. Some materials, such as certain types of stainless steel, may not be suitable for use on induction cooktops. Always refer to the product's use and care guide for specific recommendations and precautions.

Avoid thermal shock to prevent cracking
Glass cooktops are convenient and easy to use, but they require careful handling to prevent damage. One of the most common issues with glass cooktops is cracking due to thermal shock. Thermal shock occurs when a hot pan is placed on a cool glass cooktop, causing the glass to expand rapidly from the heat. This rapid expansion can lead to cracking or even shattering of the glass.
To avoid thermal shock and prevent cracking, there are several precautions you can take:
- Always ensure that the glass cooktop is at room temperature before placing a hot pan on it. Allow the cooktop to warm up gradually.
- Use trivets or heat-resistant pads: Place hot pans on trivets or heat-resistant pads designed to protect glass cooktops. These accessories act as a barrier between the hot pan and the glass surface, distributing the heat more evenly and reducing the risk of thermal shock.
- Handle with care: When placing a hot pan on the cooktop, avoid dropping or sliding it. Gently set it down to minimise the impact and reduce the chances of cracking.
- Choose suitable cookware: Select cookware with smooth, flat bottoms that are compatible with glass cooktops. Avoid using cast iron pots and pans, as they are known for scratching and can cause damage.
- Monitor for cracks: Regularly inspect your glass cooktop for hairline cracks or chips. Even small cracks can worsen with heat, so it's important to address them promptly and consult a professional for repair or replacement.
By following these simple guidelines, you can effectively avoid thermal shock and prevent your glass cooktop from cracking. Remember to always refer to your product's use and care guide for specific recommendations and precautions to ensure the longevity of your appliance.

Use trivets or heat-resistant pads
Glass cooktops are prone to cracking from thermal shock and surface scratches from heavy cookware. To avoid thermal shock, which can cause cracks, it is recommended to use trivets or heat-resistant pads when placing hot pans on a glass cooktop. This protective barrier will safeguard the surface of the cooktop from the intense heat of the pan.
Trivets are small stands or platforms made of materials that can withstand high temperatures, such as metal, silicone, or ceramic. They are designed to be placed between a hot object and a surface to protect the latter from heat damage. Trivets come in various shapes, sizes, and designs, making it easy to find one that suits your needs and kitchen aesthetic.
Heat-resistant pads, also known as hot pads or potholders, are made of insulated or heat-resistant materials, such as silicone, cotton, or synthetic fibres. These pads are placed on the cooktop before setting down a hot pan, creating a protective layer. Some heat-resistant pads are also designed to be used as trivets, offering dual functionality.
When selecting a trivet or heat-resistant pad, it is important to ensure that it is large enough to accommodate the size of your pans. It should also have a non-slip base to prevent accidental movement and potential damage to the cooktop. Additionally, opt for materials that can withstand high temperatures and have a high melting point, such as silicone or metal, to ensure maximum protection for your glass cooktop.
By using trivets or heat-resistant pads, you can effectively protect your glass cooktop from thermal shock and scratches. This simple precaution will help extend the lifespan of your cooktop and maintain its sleek appearance. Remember to also follow other care instructions, such as cleaning spills promptly and avoiding abrasive materials, to keep your glass cooktop in optimal condition.

Clean spills promptly with non-abrasive cleaners
Glass cooktops are prone to cracking from thermal shock and scratches from heavy cookware. To prevent scratches, clean spills promptly with non-abrasive cleaners. Here are some detailed steps to effectively clean spills on a glass cooktop:
Firstly, ensure the cooktop is turned off and completely cooled down before cleaning. Hot surfaces can cause burns if accidentally touched during cleaning. Use a microfiber cloth or paper towel to wipe down the cooktop surface, removing any crumbs, liquid, or spilled food.
For tougher stains, a non-abrasive cleaning pad can be used with a cleaning solution. Sprinkle a little baking soda or a non-abrasive cleanser on the affected area and rub with a damp cloth. Rinse and wipe the surface with a microfiber cloth to remove any remaining residue.
For burnt-on grime or discoloration, a more intensive cleaning process is required. Lay a hot, moist towel on the glass to soften the residue, then carefully scrape off the burned bits using a razor blade or the scraper from a cooktop cleaning kit. Repeat this process as needed, depending on the severity of the buildup.
Commercial cleaners designed specifically for glass cooktops can also be used. Apply a few drops of the liquid cleaner to the surface and cleanse with a non-abrasive cleaning pad. Remove the cleaning solution with a damp cloth and wipe dry with a microfiber cloth.
DIY cleaners can also be made by combining equal parts white vinegar and water in a spray bottle, with a bit of dish soap for tougher stains. Apply the mixture to the surface and let it sit for a few minutes to break down any residue.
By following these steps and using non-abrasive cleaning tools and solutions, you can effectively clean spills on a glass cooktop and prevent scratches or other damage.

Avoid cast iron cookware
While cast iron cookware can technically be used on a glass cooktop, there are several reasons to avoid doing so.
Firstly, cast iron is heavier than other types of cookware, and glass cooktops are susceptible to damage from heavy objects. The weight of cast iron can easily chip or crack the glass surface if the cookware is dropped or dragged across it. To avoid this, it is important to gently place cast iron pans on the surface and refrain from sliding them around during cooking. This can be inconvenient and may not align with your natural cooking style.
Secondly, cast iron retains heat for a long period, which can be a disadvantage if your recipe requires quick adjustments to the temperature. Traditional electric cooktops, in particular, can take longer to heat up and cool down due to cast iron's excellent heat retention. This may require you to modify your cooking methods or recipes to accommodate the slower response time.
Additionally, cast iron cookware often has a rough bottom surface, which can cause scratches on the glass cooktop if dragged or slid across it. Even with careful handling, small scratches may still occur over time. To minimize scratches, it is recommended to lift and gently place the cookware instead of sliding or dragging it.
Finally, glass cooktops require special care and maintenance to maintain their sleek appearance. After cooking with cast iron, it is important to promptly remove the cookware from the glass surface and clean any spills or residue to avoid scorch marks and stains. This may involve additional steps such as using a scraper to remove food soils and wiping down the surface with hot water.
In summary, while it is possible to use cast iron cookware on a glass cooktop, it may be advisable to avoid it due to the potential for damage to the glass surface, the inconvenience of modifying your cooking style, and the additional care and maintenance required. Using alternative types of cookware that are better suited for glass cooktops, such as aluminum or ceramic, may provide a more convenient and safer cooking experience.
