Induction cookers are not a cheap investment. Although their cost has dropped in the last few years, they are still more expensive than electric or gas stoves.

So when you decide to invest in an induction cooker, you want to make sure that it stays in the best condition possible.

There are a variety of materials that are suitable for use on your induction cooker, but one of the most popular is cast iron. But, with it being such a rough material, the question is whether the cast iron will scratch your induction cooktop? Let’s take a look.

Induction stoves need specific cookware in order to work. This is because induction cookers rely on electromagnetic fields to heat the base of your pot or pan. Therefore, the base of your cookware must have magnetic properties.

The simplest way to check if a pot or pan is induction compatible is to place a magnet on its base. If it sticks firmly, it will work on your induction cooker. If it sticks weakly or it doesn’t stick at all, it is not suitable for your induction cooktop.

What Cookware is Suitable for Induction?

Pots and pans that have bases made with steel, cast iron, enamel cast iron, and certain stainless steels are induction compatible. Stainless steel needs to have iron in the base to work with induction. What it comes down to is how much nickel is used in the stainless steel as nickel obstructs the magnetic field.

Aluminum, glass, and copper are not suitable for induction stoves. However, if there is a layer of magnetic materials in the base, the pot or pan can then be used on the induction cooker.

The benefit of using cast iron is that it is 100% compatible with induction cookers, which means that they will always work. Although they are heavy and large, their all-iron build guarantees that they are suitable for magnetic induction cooking.

Unfortunately, there is a downside to using cast iron which is that it is easy to scratch the surface of your induction cooker as it is made from glass. So is there a solution?

How to Prevent Cast Iron from Scratching Your Induction Cooktop

To keep the surface of your induction cooktop looking smooth and pristine when using a cast iron pan and pot, there are a few things you can do to prevent scratches.

You can simply place something thin and non-magnetic between the burner and the pot or pan. This layer can be anything from newspaper and paper towels to silpat mats and parchment paper.

As induction cookers use magnetic fields to heat the base of the pan, the surface of the cooker doesn’t get hot. This means that the paper will not burn or catch fire. This allows you to keep your induction cooktop scratch-free.

It is important to remember that the base of the pot or pan does get hot. This isn’t a problem as it is very unlikely that the paper will catch fire, but you should always be vigilant when using paper.

Why You Should Use an Induction Cooktop

There are many reasons why you should use an induction cooker in your home, including:

  • The surface of the cooker doesn’t get hot.
  • Your kitchen doesn’t get hot as there is minimal extra heat created from the burner.
  • Liquids don’t burn to the cooker as it is not magnetic. This makes it easier to clean.
  • It is unlikely that you will burn a surrounding item as the cooktop doesn’t get hot.
  • Induction is a highly efficient cooking option as they are around 90% efficient.
  • Induction cookers cook your food very quickly due to the direct heat.
  • Due to this faster cooking rate, you save more energy and money.
  • Induction cooktops are very sensitive to temperature adjustments, allowing you to cook your food with more precise control.
  • Once you remove the cookware item from the burner, the source of heat is gone. This means the burner can’t be left on, so the risk of an accidental fire is eliminated.


Although using cast iron on your induction cooker bears the risk of scratching the glass, if you take the proper precautions, you can reap the benefits of using durable cast iron cookware with your induction stove without worrying. There are so many benefits to using an induction cooker – do not let cast iron scare you.
