If you’re shopping for the best microwave oven, you may need a few appropriate dishes to cook your food in. Non-microwave safe containers pose a health risk to you and your family. As the microwave’s electromagnetic waves heat your food, cheap plastic dishes will melt and may leak dangerous chemical compounds into hot foods. So, before you cook anything in your microwave oven, make sure you’re using microwaveable containers. Keep reading to learn what is microwave safe when it comes to dishware.
Using non-microwavable containers in your microwave can be a costly mistake. In addition to the risk of ingesting toxic materials from the wrong plasticware, using foil-lined containers in the microwave may also affect your health. You can also damage the microwave itself or, worse, start a fire.
Look for the microwave-safe symbol on the bottom of your dish before using it in the microwave.
Of course, if you do suspect that you’ve damaged your unit by cooking with the wrong dishes, you can easily repair some issues at home, such as replacing a microwave oven fuse. Alternatively, if your microwave turns off frequently or the microwave starts when the door closes, these might be other issues completely.
Microwave-safe plastic dishes don’t get hot in the microwave and are great to use. If a plastic container is microwave-safe, it should be marked on the bottom as such. We don’t recommend heating plastic containers from takeaway services, though. Those containers are usually cheaply made, and they are not suitable for reheating your leftovers. The same is true for water bottles and other disposable dishes.
Most ceramic containers are safe to microwave and should stay cool over long cooking times. That said, avoid ceramic plates with a metal handle or a metal rim finish.
Even though paper plates are treated, they are entirely safe to microwave. That said, you may want to skip the paper plates if your cooking method involves wet or frozen food.
Never use metal pans or aluminum foil in the microwave under any power setting. While aluminum containers are technically microwave-safe, you need the metal to be as flat as possible. Even tiny aluminum peaks or ridges can spark, potentially damaging the internal components of your microwave. If your microwave has electrical damage, learn how to fix a microwave door switch.
While some styrofoam containers are safe to microwave, most are not. So, if you do not see any clear microwave-safe markings, you shouldn’t use the foam container for food cooking.
First, turn your food container over and look for the microwave-safe symbol on the bottom. If you do not see makings that indicate whether microwave cooking is safe to do in this dish, you need to test it before you make pizza in a mug.
Take the container in question and place it in the microwave. Pour a cup of water into the container and cook it for one minute. If the cup of water gets hot, but your container is cool, it is a safe container. However, if the water and the dish are hot, it is a non-microwave safe container.
An easy way to know something isn’t microwave-safe? Paper or foil should never go in the microwave. Even if you’ve heard about opening a sealed envelope in a microwave, don’t do it. You’re risking fire danger.
Never use aluminum containers in your microwave. In addition to affecting brain health, metal might spark in your microwave and damage your microwave’s circuitry.
Are microwaves bad for your health?

Can you microwave paper towels?
You can use a paper towel inside a microwave. In addition, you can use other paper products like wax paper and parchment paper. Many cooking methods call for covering food with a paper towel to absorb water molecules. That said, never use brown paper bags in the microwave.
