Ceramic and microwave safe glass containers are usually fine to use in the microwave. However, be careful with thin glass or ceramic as they might break due to high temperatures. To stay safe, it’s best to use dishes that are specifically labeled as “microwave-safe” or “heatproof.”

What to Consider When Selecting Microwave-Safe Containers

When selecting containers for your microwave, there are a few important things to consider:

Look for Labels that Indicate Microwave Safety: Manufacturers label plates, bowls, and cups that are suitable for use in the microwave. If a container does not have this label, it’s advisable to avoid using it in the microwave.

Ceramic and Glass Options: Although certain ceramics and microwave safe glass containers may not have specific labels indicating their suitability for microwaving, they generally can be used safely. However, thicker ones reduce the risk of thermal shock – sudden expansion or contraction that could cause breakage.

Thermal Shock Resistant: Watch out for thermal shock to avoid breakage of glass containers and ceramic dishes due to sudden temperature changes. To prevent this, opt for thicker glass or ceramic containers and refrain from subjecting them to extreme temperatures.

Microwave-safe container: When it comes to plastics and other microwave safe materials like cardboard boxes, make sure they are explicitly labeled as microwave safe plastic containers before using them in the microwave. Using unsuitable materials can lead to deformation, melting, or potential release of harmful substances.

When Should You Avoid Using a Container in the Microwave?

When it comes to using a microwave- safe container is the key. Be cautious with containers that can get too hot, don’t heat evenly, or might cause sparks or fires. Here’s what you need to know:

  1. Stay Cool: The best microwave safe materials won’t become overly hot during use. It should instead absorb some of the heat while keeping its coolness when touched.
  2. Heat Distribution Matters: Not all containers are created equal in terms of how well they distribute heat. Ceramic and glass containers are great options as they tend to keep cool while ensuring even heating for your food.
  3. Safety of Plastic Containers and Metal Trims: Not all plastic containers are microwave safe plastic containers, so it’s important to check if they are specifically labeled as microwave-safe. Be cautious when using glass or ceramic dishes with metal trims or decorations, as these can cause issues when microwaved.
  4. Sparks and Arcing from Metals: Microwaving metal objects can result in sparks, electrical arcing, and even potential fire hazards. It may also cause damage to the microwave due to short circuits.

Why Some Plastics Are Considered Safe for Microwaving While Others Aren’t?

The safety of using plastics in the microwave is a matter of debate among experts. While some plastics can melt or catch fire under extreme conditions, these incidents are rare.

The main difference between microwave safe plastic containers and unsafe plastics lies in whether they release chemicals that could seep into food when heated, as pointed out by Dr. Olga Naidenko from the Environmental Working Group.

According to the U.S. Food and Drug Administration, plastic containers labeled as “microwave-safe” are considered suitable for use in microwaves because they do not emit harmful substances or plasticizers like BPA when heated.

  • Place the unmarked plastic, glass, or ceramic container in the microwave with no food inside.
  • Put a cup of tap water next to it.
  • Set the microwave on high and heat for one minute.
  • After heating, check how hot the empty container is by either using an oven thermometer or touching it carefully.
  • If the tested container stays cool, it’s safe to use in the microwave.
  • If it feels slightly warm, only use it for reheating purposes as a precautionary measure.
  • If it becomes extremely hot during testing, do not put it in this appliance at all since it isn’t suitable.

Precautions When Microwaving Container

Switch to Microwave Safe Food Containers: Before putting food in the microwave, move it from takeaway containers, cold-storage plastic containers, or polystyrene trays into microwave safe plastic containers or others like ceramic, glass, or Tupperware/Rubbermaid plastic.

Avoid food packaging: Materials used in food packaging are frequently unsafe for use in microwaves. You should refrain from heating food in or directly on colored paper plates, paper towels, brown paper bags, or plastic shopping bags. These substances have the potential to emit chemicals that could contaminate your food.
