When you’re about to microwave something, it’s always a good idea to check the owner’s manual or the labels of your cups. You might be surprised to find that not all materials are safely used in the microwave. Items like certain plastics or metals can pose a risk, while ceramic and microwave-safe glass cups are usually fine.
Some cups can handle heat, but always make sure to verify. Check if there are any warnings on the label, as materials not suited for microwaving might warp or even catch fire.
Microwave-Safe Glass and Ceramic Items
Glass and ceramic cups, mugs, or bowls are usually safe to use in the microwave, but there are some exceptions. Handmade pottery or painted dishware with metallic inlays may not be microwave-friendly. Always check for a clear label indicating the item’s safety for microwave use.
Plastic Containers and Tupperware
When it comes to plastic containers like Tupperware, make sure they are microwave-safe. Avoid using old or cracked containers, especially those that are discolored. Single-use plastics, like yogurt or cottage cheese containers, aren’t meant for the microwave and can melt or warp.
Paper Plates and Microwave Use
Paper plates are often disposable and not designed for microwave use. Many are coated with a thin plastic layer, which can melt when microwaved. To be safe, look for those labeled microwave-safe, as regular ones might catch fire or become soggy.
Paper Towels and Microwave Use
Paper towels can be used to cover foods when microwaving, but make sure they are microwave-safe. Always check for any printing or recycled material that may be a safety hazard. It’s a good idea to heat in intervals to prevent the paper from catching fire, especially with brown paper bags.
Ziploc Bags in the Microwave
When using Ziploc or food storage bags in the microwave, always follow the label directions to ensure they are microwave-safe. Some brands are fine for defrosting or reheating, but be sure to check the bag for any warnings or directions before microwaving.
What can’t you put in the microwave?
When using the microwave, not all materials are safe. Some containers made from certain materials might not handle the heat, leading to unsafe results. Plenty of things like liquid-filled cups and certain food containers can’t be placed in the microwave because they might transfer heat unevenly. Be cautious, and always ensure the microwave-safe label is present on your containers. For the best experience, check OUR COLLECTION of varieties to ensure safe use.
Styrofoam Cups and Microwave Use
Styrofoam is generally not microwave-safe unless it’s clearly labeled. Always check the label to ensure it’s the right type for microwaving, as some Styrofoam can’t handle the heat and may release harmful chemicals. For the best results, it’s best to keep out any Styrofoam that isn’t labeled microwave-safe.
Cardboard
Cardboard cups and takeout boxes are not the best choice for the microwave. The materials used in some cardboard containers, like glues or waxes, can create a fire hazard or even cause sparks. When using paper products or microwave-safe bowls, make sure they are labeled as microwave-safe to avoid any safety hazard.

Metals including stainless steel and aluminum foil
Using metals like stainless steel, iron, or aluminum foil in the microwave is tricky. These hard metals can reflect microwaves, leading to uneven heating or even arcing which causes dangerous electric sparks. Aluminum foil, especially when crumpled or with wrinkles, can create a fire hazard. It’s always safer to use a microwave-safe container for cooking or reheating your leftovers. Always follow the owner’s manual to avoid damaging your microwave and metal surfaces inside.
Identifying Microwave-Safe Items
To be sure that a container is safe for microwave use, always check for a microwave-safe label or symbol on the bottom or back of the item. It’s a good idea to confirm what the container is made of, as some materials might have exceptions. If in doubt, it’s best to leave it out and choose a microwave-safe container instead. Over the years, you’ll learn to determine what works best and ensure your microwave stays in top shape.
