How to protect glass top stove from cast iron
These steps will help you safely use cast iron equipment on glass top stoves or any other surface without scratches or damages.
1. Take proper precautions
a. Make sure you wash your cast iron cookware before using it
Use a scrubber or sponge and a tiny amount of dish soap to get rid of any food residues. You need to focus more on the bottom of the pan, as this area is more likely to contain built-up carbonization, or black marks. Then let your cast iron cookware air-dry completely before using it on your glass top stove.
Failure to clean off the black marks can result in them smearing and staining your glass top stove.
b. Make sure the cast iron cookware you choose to use has a smooth bottom
You need to check and make sure there are no chips, cracks, uneven edges or bumps and the bottom of your cast iron cookware is smooth, else there is every tendency that the top of your glass top stove would get scratched more easily.
c. Season your cast iron cookware entirely
Most people only season the inner part of their cast iron cookware as they feel that’s the only important area which is a big ‘no, no!’.
Cast iron seasoning is the application of a thin layer of cooking oil to the surface of your cast iron pot, pan or skillet to fill the tiny pores that are naturally a part of any cast-iron cookware. This is done in order to make it easy to clean and get food off its surface while also promoting its longevity and durability.
You must season every part of your cast iron cookware to prevent any uneven surfaces, rough parts or bumps from forming as these will wear away your glass top stove faster than you can think.
You must note that the kind of oil you choose to season your cast iron cookware will go a long way in determining its durability and lifespan.
d. Lift your pans carefully
Due to the smooth surface of glass top stoves and the fact that cast iron is heavy and a little cumbersome to lift especially when hot, it’s quite tempting to want to slide or skid your cast iron pan across the glass cook top once you’re done cooking.
Don’t do this, instead use both hands to lift the handle, which allows you to move the pot or pan safely, and be careful not to slide or drop them on the glass top stove to prevent damage or in extreme cases shattering.
e. Use lightweight pots and stainless-steel cookware whenever possible.
f. Use cast iron pans or pots that match the dimensions of your glass top stove
Make sure your top stove is turned off and completely cool to the touch, and then use a measuring tape to get the width of your main burner. Next, check the diameter of your cast iron cookware to see if it fits snugly on the top of the glass top stove.
Don’t use cast iron cookwares that are an inch or larger than the width of the burner to avoid uneven heating—Yahoo!
To put this into context, don’t use a glass top stove that is 12 inches wide on a glass top stove that is 10 inches wide.
g. Avoid using aluminum foil on glass top stoves as they can leave marks and scratches on the delicate cooking surface.
h. Always adhere to manufacturer’s instructions when using and cleaning your glass top stove and cast iron cookware.
2. Use heat diffusers
Depending on your kitchen needs and budget, you can choose a perforated aluminum diffuser, a diffuser made with wire coils, or a flat steel item.
Heat diffusers help to control the amount of heat from your stove top and dispense it throughout the bottom surface of your pot or pan. Just think of the diffuser as a buffer between the glass top stove and the things you put on it.
Using a heat diffuser is one of the cheapest and most convenient ways to prevent your glass top stove from cracking or scratching.
Here’s how to use a heat diffuser:
- Choose a heat diffuser that fits on your glass top stove burners perfectly
- Set the flat side of your heat diffuser on the glass top stove: Look on both sides of the diffuser for a curved and flat edge. The flatter edge should be set on the glass top stove as less likely to shift while you’re cooking.
- Don’t put any food into your cast iron cookware until you have the pot or pan and diffuser in place, and your pot or pan is properly centered on the diffuser so the stove’s heat can spread evenly.
- Turn your glass top stove burner to a low temperature or heat setting: Cast iron doesn’t heat up evenly, so it’s best to maintain a balanced temperature whenever you cook over a glass top stove.
- Hand wash your diffuser when it gets dirty and leave it to air dry completely for a day or more before using it again.
3. Get a glass cooktop protector
Glass/ceramic cooktop protectors are thin, easy to clean and foldable covers made from rubber or silicone. These protectors are anti-slip and heat resistant and are a cheap and easy way to prevent damage(s) to the surface of your glass top stove.
A glass cooktop protective cover is another buffer between your glass cooking surface and cast-iron cookware. A ceramic stove top protector will work just fine if you can’t find one meant for glass cooktops.
