Using Cast Iron on Glass Stove Top

Many might also be wondering, can you use cast iron on a glass top stove in the first place? Well, the answer to this is yes. You technically can, but it is not advisable due to various reasons. Here are some of them:

  • Heavy Weight – Iron cast pans are heavy cookware since they are made of iron, so it is not ideal to use it on a glass stove top. Furthermore, glass stove tops are made of ceramic glass which is sensitive to heavy weights.
  • Uneven Bottom – The ideal cookware for glass stove tops are those that have an even and smooth bottom such as ceramic pans so that it wouldn’t leave a scratch on the glass. However, cast iron pans are not like that. They have textured bottoms.
  • Size Incompatibility – Again, glass stove tops were not designed to cater to cast iron cookware; hence, the cookware and the stove top’s sizes don’t match. This can be an issue in even heat distribution in the pan, leaving the center too hot and the part not covered by the stove top too cold.

Tips on How to Protect Glass Top Stove from Cast Iron

If you still really want to use cast iron cookware despite all of the things mentioned above, here are some of the things you can do to mitigate the risk of damaging your glass stove top:

1. Lift

Using a cast iron pan on a glass stove top makes it a habit to lift the pan instead of sliding it. This will prevent scratches from happening on the glass. Even if you just want to arrange the pan’s position, do it by lifting it totally. Do not slide cast iron pans on glass stove tops at all costs.

2. Wash first before heating

You may already know that you need to wash your cast iron pan after using it, but it is important to also wash it before putting it on to the glass stove top. The logic behind this is that cast iron cookware tends to have more leftover deposits of oils and food, so when you put them into the glass stove top without washing it first, it may leave smudges on the surface that are a pain to remove.

3. Use a Heat Diffuser

One way of using a cast iron pan on your glass stove top without damaging it is by using a heat diffuser. A heat diffuser is invented to distribute and diffuse heat around the base of a pan. It is made of high-grade metal that prevents direct contact of the glass stove top’s uneven bottom.

How to Avoid Scratches on Glass Stove Top when Using Cast Iron Pans

Being easily scratched is one of the major downsides of owning a glass stove top. It can significantly affect its aesthetics and even its performance as well. However, there are several things that you can do to prevent your glass stove top from being scratched when using cast iron.

Here are some of them:

1. Be cautious

If you want the best of both worlds when using a cast iron pan and glass stove top, then the best thing you can do to avoid scratches is by being extremely careful when you cook. Do not slide the cookware but instead make a habit of lifting it up.

2. Avoid cast iron pans with rough bottoms

Another way to avoid scratches is by first checking the bottom of your cast iron. If you feel like it has lumps and a really sharp edge, it is best not to use it at all because it will definitely cause some damage.

3. Keep it clean all the time

Make sure that your glass stove top is clean all the time since if you don’t deal with dirt on it immediately, it can be a challenge for you to do so later on. Cleaning it regularly can also prevent scratches caused by too much rubbing on stubborn dirt that has accumulated.

Best Practices for Glass Stove Tops

Since glass stove tops are major investments, it is no surprise why you would want to make sure it lasts long while still looking its best. Here are some general best practices you can do on your glass stove tops to maintain it:

  • Follow the manufacturer’s instructions. Not all glass stove tops are made equal, so the operation and maintenance might also have some difference, so it is best to read the manufacturer’s instructions first to know how to best take care of it.
  • Use cleaning clothes. Make it a habit to clean the surface of the glass stove top when it’s cooled down using a cleaning cloth.
