9 Practical Tips to Protect Your Glass Top Stove from Cast Iron Cookware

Have you ever been excited to use a new glass cooktop, only to have it crack under a heavy pot or cast-iron skillet? The use of cast iron on glass cooktop surfaces can spell disaster, especially if you aren’t careful.

If you just bought a new stove with a glass cooktop, and own lots of cast iron pots and pans, don’t despair. Using cast iron on a glass top stove can be done safely and we’ll show you just how. This article will look at how to protect glass top stove from cast iron equipment.

Why is it important to protect your glass top stove?

Glass top stoves are becoming increasingly popular in modern kitchens due to their sleek and stylish appearance, even heating, and ease of cleaning. However, they are delicate and prone to scratches, chips, and cracks.

The cost of replacing a damaged glass top stove can be significant, making it crucial to take precautions to protect it from damage.

The Risks of Using Cast Iron Cookware on Glass Top Stoves

1. Scratches and Chips

The rough and heavy surface of cast iron cookware can easily scratch or chip the glass surface of a glass top stove. This damage is not only unsightly but can also lead to further problems like cracking and even complete failure of the stove.

Scratches and chips can also trap dirt and debris, making it more challenging to clean the surface and increasing the risk of further damage.

2. Thermal Shock

Cast iron cookware is known for its ability to retain heat for a long time. However, this can be dangerous when used on a glass top stove. Sudden changes in temperature, such as placing a hot cast iron pan on a cold stove, can cause the glass to crack due to thermal shock.

The thermal shock can also cause uneven heating of the glass top stove, leading to further damage.

How to Protect Glass Top Stove from Cast Iron Pans

Cast iron cookware is heavy-duty and can be rough on your stovetop and counters. These steps will help you safely use cast iron on an electric stove and cooktops. When followed carefully, you won’t have to replace a glass stovetop every few months!

1. Use a Heat Diffuser

A heat diffuser is a device that helps distribute heat evenly and prevents hot spots. It is especially useful when cooking with cast iron cookware on a glass top stove. Place the heat diffuser on the stove, then place the cast iron pot or pan on top of the diffuser. This will help distribute the heat more evenly and prevent direct contact between the cast iron cookware and the glass top stove.

2. Use a Protective Mat or Trivet

Another way to protect your glass top stove from cast iron cookware is to use a protective mat or trivet. Place the mat or trivet on the stove, then

place the cast iron pot or pan on top of it. This will help prevent direct contact between the cast iron cookware and the glass top stove and reduce the risk of scratches or damage.

3. Lift and Move Cookware Carefully

When using cast iron cookware on a glass top stove, it is crucial to lift and move the cookware carefully. Do not slide or drag the cookware on the stove surface, as this can scratch or chip the glass. Instead, lift the cookware and move it gently.

4. Keep the Stovetop Clean and Free of Debris

A clean stovetop is essential for preventing scratches and damage to the glass top. Use a soft cloth or sponge to wipe away any spills or debris immediately. Avoid using abrasive cleaners or scrubbers, which can scratch the surface.

5. Use Cookware with Smooth and Flat Bottoms

When purchasing cast iron cookware for use on a glass top stove, look for cookware with smooth and flat bottoms. Avoid cookware with rough or uneven bottoms, as they can scratch or damage the glass top. Smooth and flat bottomed cookware will provide more even heat distribution and reduce the risk of damage to the stove.

6. Avoid Dragging Cookware on the Stovetop

As mentioned earlier, it is essential to avoid dragging or sliding cast iron cookware on the glass top stove. Always lift the cookware and move it gently to prevent scratching or chipping of the glass surface.

7. Be Mindful of Temperature Changes

Cast iron cookware retains heat for a long time, and sudden changes in temperature can cause the glass top stove to crack due to thermal shock. Therefore, it is essential to be mindful of temperature changes when cooking with cast iron on a glass top stove. Allow the cookware to cool down before placing it on the glass top stove, and avoid placing cold cast iron cookware on a hot stove.

8. Choose Cookware with Rounded Edges

Cookware with sharp edges, such as skillets, can scratch the glass top stove. To avoid this, choose cookware with rounded edges. This will reduce the risk of scratches and chips on the glass surface of the stove.

9. Use Smaller Cookware

Using smaller cookware can also help protect your glass top stove from damage. Smaller pots and pans are lighter, making them easier to lift and move carefully. They also distribute heat more evenly, reducing the risk of hot spots and thermal shock.

Protecting Glass Top Stove from Scratches

Here are a few things you can do to prevent and remove scratches from your glass cooktop:

• Use a cooktop protector mat and change it when it is worn out. It is also important to clean these covers once a week, or after a hectic and substantial cooking session.
• Don’t slide your pots and pans back and forth along your stove. Lift them away and set them down gently instead.
• Use lightweight pots and stainless-steel cookware whenever possible.
• Scrub the bottom of your pots and pans regularly and remove the grease and burnt bits of food there.
• Clean spills right away and never use steel wool and metal sponges on your glass cooktop.
• Avoid using aluminum foil on these kinds of stoves as they can leave marks and scratches on the delicate cooking surface.
• To fix small scratches, make a paste from baking soda and water and gently buff away the scratch with this mixture. Make sure the paste is wet and rubbing dry baking soda will make the damage worse.
• To keep your glass cooking surface looking new, use glass cleaner to keep things clean and shiny.
• Follow manufacturer’s instructions when using and cleaning your stove and cookware.
• Regularly season the entire surface of your cast iron cookware. You should also use newer versions of cast iron skillets as these have much smoother bottoms than older ones.
• Avoid using cookware with round bottoms as they cause scratches. Instead, use pots and pans with smooth and flat bottoms, as they are more stable and will shift around less, reducing the chances of scratching up your glass cooktop.
