If you have any cooking experience at home, you may have a glass top stove or cookpot at this time, or it should be. It’s a time of motion. No one wants to take the risk of cooking with the extra hassle. Now the glass top stove is a modern solution to hassle-free cooking. So, its appeal is increasing day by day.

Although the glass and ceramic top stove are modern, glossy, and appealing, it needs to be used with extra care. You can’t use it roughly, it can break or iron pans or skillets can scratch its surface. So, if you carelessly choose glass top stoves, ranges, and the right apliance/ pan for cooking, it will be a risky decision for you.

Most modern homes are now equipped with electric and gas stovetops. Because they understand the importance of your time, you have the power to control the heat level suitable for your home cooking. However, glass top stoves limit your ability to cook with certain tools.

Cast iron skillets have been around for generations and have recently become more popular. However, some of them still couldn’t overcome all their limitations, and couldn’t be completely glass-top friendly. 

Why Shouldn’t Use Cast Iron on Glass top Stoves?

There are many reasons why you may have trouble using a cast-iron skillet or pan on a glass top stove, or you may not be able to use it. It’s good to know these as a precaution.


Cast iron pans or skillets themselves are much heavier, compared to aluminum or stainless steel, and glass much lighter. Also when food and water are added to it, the weight increases further, which the light glass top can’t carry occasionally, breaks, or is in danger of breaking. Modern glass tops, however, are relatively stiff, and most of these glass cooktops can handle the weight of a normal daily cast iron cookware.

Flat Bottom

For glass and ceramic stoves, the pan or skillet needs to be flattened to distribute heat. Cast iron pans usually don’t have a flat bottom. Some will get a circular ridge around the outside edge, which will not match the proper glass top. In general, your pans aren’t flat. Some will get relative flats, they’re not perfectly flat. These may not take in the proper heat and may create hot spots at the bottom of the pan.

Many cast iron pots are much larger than your glass top stove burner. If the pot is larger than the adjustment size on the stove, the pan will not be able to distribute heat evenly across its surface. This will reduce the heat transfer capacity or cooking speed of the stove relatively and will reduce the holding capacity of the stove and can damage the cooktop surface.


Cast iron has a rough finish, which easily scratches the surface of the glass cooktop. Cast iron coated in porcelain enamel is an alternative to a type of glass top. To avoid scratches, the finish should be smooth and the cast iron should be completely covered. When you use the enameled pan in a very high-temperature setting for a long time, the pan will retain heat which may cause damage to the glass top later on.
