If you are not careful when using cast iron on a glass cooktop, you can damage the cooktop by dropping the pan or dragging it across the surface.

Cast iron will not scratch your cooktop if you use it properly. However, if you drag the pan across the surface, it can cause scratches. But that’s not all. To protect the glass top stove from scratch, you have to use it carefully.

How to use cast iron on a glass top stove?

1. Make sure the bottom of your pan is smooth

First and foremost, you want to make sure the bottom of your pan is smooth. Any roughness can cause scratching, so it’s best to use a pan that has a smooth bottom.

If you’re not sure if your pan is smooth enough, you can always test it out by placing it on a sheet of glass or another smooth surface. If it slides around easily, then it should be fine to use on your glass top stove.

If your pan is too rough, you can try sanding it down with a fine-grit sandpaper. Just make sure to sand evenly so you don’t create any unevenness in the bottom of the pan.

2. Moderate Heat

The next thing to keep in mind is to use moderate heat when cooking. Glass top stoves are sensitive to high temperatures, so it’s best to stick to lower or moderate settings. High heat can damage the cooktop and cause the pan to stick.

If you need to use a higher setting, it’s best to do so for a shorter period of time. For instance, if you’re boiling water, you can turn up the heat to high for a minute or two and then turn it back down to low or moderate once the water has started to boil.

3. Avoid Placing Hot Pans Directly on the Glass Surface

When you’re finished cooking, it’s important to avoid placing hot pans directly on the glass surface. The sudden change in temperature can cause the glass to crack or shatter.

Instead, place the pan on a heat-resistant trivet or towel. This will help to protect the glass and keep it from shattering.

4. Clean Up Any Spills Immediately

It’s important to clean up any spills immediately. Glass top stoves can stain easily, so it’s best to wipe up any messes right away.

If a spill does happen to stain the stove, there are a few ways to remove the stain. You can try using a glass cooktop cleaner or white vinegar. Just apply the cleaner to a cloth and wipe away the stain.

You can also try making a paste out of baking soda and water. Apply the paste to the stain and let it sit for a few minutes before wiping it away.

5. Choose the Right Size Skillet

When choosing a skillet to use on a glass top stove, it is necessary to take into account the size of the burner. Make sure the skillet you are going to buy should be smaller or equal to the size of the burner.

If the skillet is larger than the burner cooking area size then food would not cook evenly.

For instance, if you own an electric stove with six-inch burners, then it would be best to buy eight-inch skillets or smaller than that.

In general, it is best to avoid using cookware that is larger than the burner since it can lead to uneven cooking.

How to protect the glass top stove from cast iron?

1. Gently Lift and don’t drop it

When you’re finished cooking and need to remove the pan from the stove, be sure to lift it gently. Avoid dropping the pan, as this can cause damage to the cooktop.

If you do drop the pan, inspect it for any cracks or chips. If there are any, it’s best to replace the pan so you don’t run the risk of damaging your cooktop.

2. Use Skillet With a Smooth Bottom

When it comes to glass top stoves, it’s important to use cookware that has a smooth bottom. Any roughness can cause scratching, so it’s best to use a skillet that has a smooth bottom. For Example Enamelled Cast Iron.

If you’re not sure if your pan is smooth enough, you can always test it out by placing it on a sheet of glass or another smooth surface. If it slides around easily, then it should be fine to use on your glass top stove.

If your pan is too rough, you can try sanding it down with a fine-grit sandpaper. Just make sure to sand evenly so you don’t create any unevenness in the bottom of the pan.

3. Use a diffuser

A diffuser is a flat piece of metal that sits between the burner and the pan. It helps to distribute the heat evenly and prevents the pan from making direct contact with the burner and prevents the pan from scorching the cooktop.

4. Don’t Drag Cast Iron Across the Stove

Another thing to avoid is dragging cast iron across the stove. The weight of the pan can cause scratching, so it’s best to lift it when moving it from one spot to another.

If you need to drag the pan, make sure to do so slowly and carefully.

4. Clean and Season skillet entirely

Finally, it is important to clean the pan after each use. Cast iron pans can be seasoned, which means that they have a coating of oil that helps to prevent rusting. This coating can also transfer to your stovetop and cause damage.

However, if you do damage your stove, it is important to contact a professional for repairs. Trying to fix a glass top stove yourself can be dangerous and may void your warranty.

By following these tips, you can protect your glass top cooktop from damage or any kind of scratches. Be sure to use the right cookware and take care when handling it.
