How to Protect Glass Top Stove from Cast Iron

  1. Season the entire pan with salt and pepper

The easiest method to protect your glass top stoves from cast iron cookware is to follow this advice.

When you use cooking oil to season cast iron cookware, you produce a carbonized coating on the pan that makes it nonstick. You obtain a smooth, uniform coating on the cast iron skillet if you season it properly. Most individuals, however, do not season the entire pan. This is something you’ll do differently.

Season the entire pan with oil and bake it upside down at a high temperature. This will coat the cast iron cookware that will be in touch with your glass top stove in a smooth coating of seasoning. Because the coating will be smooth and even, the risks of scratching your glass top stove will be much reduced, and you will have the finest protection available when using cast iron on a glass top stove.


This is the way to go if you want to avoid scratches on your glass stove. The majority of individuals season only the interior of their favorite pan, leaving the exterior rough and uneven. This rough surface might wear down your glass cooktop and cause it to crack unexpectedly. When cast iron cookware is seasoned with cooking oil, a carbonized coating forms on the pan, making it almost nonstick. Coat the entire pan with oil and bake it at a high-temperature upside down. This will coat the cast iron cookware that will be in touch with your glass top stove in a smooth, even coating of seasoning.

  1. Use Heat Diffuser

One of the simplest methods to extend the life of your glass cooktop is to purchase a heat diffuser. A heat diffuser for an electric glass-top stove distributes heat evenly across the bottom surface of a pan. The delicate surface of your range top heat diffuser will also be protected against heavy and abrasive pots and pans.

Consider the diffuser to be a barrier between the glass cooktop and the items placed on it. The diffuser is constructed of a lightweight metal that is also robust. This may be the most cost-effective and practical solution to keep your stove from cracking or scratching. Heat diffusers, which function as a barrier between your pan and the glass top stove, are a fantastic method to protect your glass top stove from cast iron. Due to the rough nature of cast iron, the heat diffusers have been engineered to be flat and smooth, protecting your glass top stove.


  1. Lift it don’t slide it

This component is essential for keeping cast iron cookware off of your glass top stove. Cast iron cookware is heavy and abrasive, two characteristics that can wreak havoc on glass. When transferring pots and pans, make sure you lift them carefully and set them down properly. The weight and roughness of cast iron are too much for glass.

Once you’ve finished cooking, it’s tempting to slide your cast iron pan over the glass stove. After all, cast iron is heavy and difficult to lift. Lifting your pots and pans, on the other hand, goes a long way toward acting as a glass stove top protection.

Because cast iron is rough and heavy, moving it across a glass surface can produce small cracks, eventually breaking the stove. Instead of slamming a pot against the glass or sliding it off the burner, carefully raise it or set it on the stove to avoid damage.

  1. Get a Glass Cooktop Protector

Another simple approach to protect your stove’s surface is to do so. A glass/ceramic stovetop protector is a thin cover that protects your cooktop. They’re anti-slip and heat resistant, and they’re composed of rubber or silicone. A heat-resistant glass cooktop cover will help keep spills, dirt, and scratches off your stovetop. They’re also collapsible and simple to clean.

Another barrier between your glass cooking surface and the cast-iron skillet is a glass top stove protection cover. If you can’t find a glass cooktop protection, you can use a ceramic stove top protector.


  1. Maintain a Clean Environment

This can apply to both individuals who utilize and those who do not use a heat diffuser. Any gritty food that may be adhered to your cast iron cookware or heat diffuser may scrape and harm the glass surface if you don’t keep it clean. Cast iron on glass is a problem in and of itself, so there’s no need to add sticky food to the mix. If you keep it clean, you’ll have a lower likelihood of harming the glass top stove.

Warm water, dish soap, and a firm sponge can clean your cast iron cookware. Remove any fat or food that has accumulated at the bottom of the pan. Burn marks and scratches on your glass cooktop may be avoided by meticulously cleaning these areas. Every day after cooking, wipe clean the stovetop to eliminate oil, spilled food, and dirt. Give your stovetop a thorough cleaning once a week. Remember, the goal is to keep dirt from accumulating and ruining your brand-new, gleaming stove!
