Can a microwave sit on metal?

Can a microwave sit on metal? This is a common question for anyone unsure of the best place to put their microwave. The truth is that microwave ovens need kitchen space. But, if you have exhausted all other free spaces in your kitchen, you must look for an alternative. Here arises our question: Is the metal option your only one?

It is okay to allow the microwave to sit on a metal shelf. This is contrary to the popular belief that the reflections in an oven can extend to the oven exterior and cause sparks on a metal shelf. Nowadays, manufacturers have redesigned this appliance to trap the excess on the interior.

What can you put inside a microwave?

When buying a microwave, you want to use it in the best way possible for it to last long. One of the ways is putting the right material in the appliance. The best way to tell what can be put in the microwave is by checking the labels or the manuals. A few of these materials are plastics, Ziploc bags, glass and ceramics, paper towels, and paper plates.


Even though plastic containers are safe for use in microwaves, there are those that you cannot use. You should never use plastics such as those used for cottage cheese and yogurt. The same rules apply to plastic to-go containers that do not state they are microwave-safe.

Also, you should not use old, cracked, and discolored plastic containers. The best plastic containers are those meant for long-term use, like Tupperware.

Ziploc bags

Ziploc has confidence in its food storage bags defrosting and reheating foods in a microwave oven. But this is only possible if you follow the label directions. If you wish to use a different bag, you must confirm that it is microwave-safe. Besides, you have to follow all the directions given. If you are unsure of the bag type you are looking forward to using or do not have access to the directions, be careful and do not use the bag in your microwave.

Glass and Ceramics

Most of the ceramic and glass dishware are microwave-safe. However, there are exceptions, like crystals and handmade pottery. Make sure they do not feature metallic paints on ceramic and glass plates, cups, mixing bowls, mugs, or bakeware.

Paper Towels

Most paper towels are microwave-safe. You can use paper towels to cover some foods to prevent them from spitting while reheating or cooking. When using a paper towel, it is advisable to use shorter intervals to help you check paper and food frequently. Never use paper towels with printing, recycled paper towels, brown paper bags, and paper lids, as they pose a possible safety hazard.

Paper Plates

You microwave plain paper plates. However, some disposable tableware tends to be coated in thin plastic. Before use, check if these plates have a microwave-safe mark.

Things not to put in the microwave?

Even though there are many things that you can put in your microwave, there are some you cannot. They include cardboard, metals like aluminum and stainless steel, and Styrofoam.


If you can microwave paper towels and plates, you may wonder if you can do the same to cardboard. After all, they are all paper products. Unluckily, these boards have waxes, glues, and other materials that are not safe for use in a microwave. There is cardboard with metal handles that might cause a spark.

If your foods are in cardboard, consider removing them and placing them in microwave-safe bowls or microwaveable plates.

Metals like aluminum foil and stainless steel

Never put containers with steel, copper, iron, and other hard metal in your microwave. In general, metal surfaces tend to reflect microwaves. This enhances the heat inside the appliance and may lead to a fire. If you use metal containers to store leftovers, put them in microwave-safe containers.

For the sake of aluminum foil, make sure the surface is flat as possible. This is because crumpled or wrinkled foil can cause arcing. Besides, foods wrapped in aluminum foil might not cook or preheat properly.


While some Styrofoam is microwave-safe, some are not. Please ensure the one you use has a label indicating they are microwave-safe. If you are not sure it is, consider not using it.
