What Is The Microwave Safe Symbol and What Does It Mean?
The microwave-safe symbol is a pictogram that features a microwave with wavy lines underneath. It is mostly used throughout Europe and North America.
These symbols were developed by the International Organization for Standardization (ISO). It ensures you easily identify safe products for microwave use.
When you find any container or dish labeled as microwave safe or microwave oven safe, it means it has been tested and found safe for use in a microwave oven therefore you don’t have to worry about the material breaking, melting, or releasing harmful chemicals when heated in a microwave.
For example, you should not use containers made of metal, aluminum foil, or materials with metallic accents in the microwave.
Microwave-safe products are intended for heating or reheating food. You can use them to heat beverages in the microwave. However, most options are not ideal for conventional oven baking or stovetop cooking.
You should refer to the manufacturer's instructions and guidelines before using any product in your microwave oven.
Following these guidelines will ensure safety and prolong the life of your appliance.
Importance of the Microwave Safe Symbol
The microwave oven safe symbol or label is essential for ensuring the safe use of containers and dishware in microwave ovens.
You can contact the manufacturer for clarification. They will provide accurate information regarding the item's suitability for microwave use.
Here are some of the advantages and importance of the microwave-safe symbol:
The primary purpose of the microwave oven-safe symbol is to provide consumers with confidence that they can use the item safely in a microwave. This unique symbol indicates that the product has been tested and deemed suitable for microwave use.
Using non-microwave-safe items in a microwave oven will cause damage to the item itself, the microwave, or both. For example, materials incompatible with microwaves will melt, warp, crack, or release harmful substances. This unique symbol will help you identify which products are appropriate for microwave heating.
If you microwave food in containers or dishware that are not microwave-safe, it can have adverse effects on your health. Certain materials, such as plastics containing BPA (Bisphenol A), can leach harmful chemicals into the food when heated in a microwave. Using products with the microwave-safe symbol will minimize the risk of contamination.
Which Materials Are Microwave Safe?
These materials are considered microwave-safe:
You can use glass containers and dishes in the microwave if they have no metallic parts or decorations. Glass is transparent to microwaves, allowing microwaves to pass through without absorbing or reflecting them significantly.
This property allows the food to be heated evenly as the microwaves can penetrate the glass and interact with the food directly.
In addition, glass is a non-reactive material. This makes it a safe choice for reheating purposes.
However, you should avoid sudden temperature changes, such as placing a hot glass dish directly onto a cold surface or immersing it in cold water immediately after microwave use.
Most ceramic dishes and containers are microwave safe. However, you should always check for the microwave oven-safe symbol.
Like glass, ceramic is a non-reactive material. Therefore, it won't react chemically with most foods or liquids.
However, you should avoid using ceramic dishes with metallic decorations. They can cause sparks and potentially damage the microwave oven.
In addition, check the ceramic dish for cracks before using it in the microwave. Damaged ceramic can lead to breakage or shattering.
Heat Resistant Plastic
Some plastics are microwave safe, but not all. Look for the microwave-safe symbol on the container or packaging. Microwave-safe plastics are designed to withstand heat without melting or releasing harmful chemicals.
However, if the containers become cracked, warped, or show signs of wear, we recommend replacing them. They may not be as safe for microwave use.
Microwave-Safe Paper Plates and Bowls
Some paper plates and bowls are specifically designed for microwave use. They are made from thicker and sturdier paper materials that withstand the heat and moisture in the microwave. They do not become soft or collapse.
However, they are not suitable for extended cooking times or high-power settings. Follow the recommended guidelines and instructions provided by the manufacturer.
Which Materials Are Not Microwave Safe?
Aluminum foil reflects microwaves and will cause sparks or even fire if it comes into contact with the oven's walls or heating elements. Therefore you should not use it in the microwave.
We recommend using microwave-safe containers or wraps specifically designed for microwave use.
Gold or Silver
Metal with gold or silver accents or coatings should not be used in the microwave. These metals will cause arcing and create sparks. This will lead to potential damage to the appliance and a fire hazard.
Plastic Storage Bags
Thin plastic bags, such as sandwich or grocery bags, are not microwave safe. They will melt or release harmful chemicals when heated. This poses a risk to your food and potentially damages the microwave.
Recycled Paper Products
Paper products made from recycled materials, such as paper towels or napkins, are not microwave safe. They may contain additives, inks, or dyes that can leach into your food or cause the paper to ignite.
Disposable take-out containers, especially those made of plastic or Styrofoam, are generally not microwave safe. When exposed to microwave heat, they melt, warp, or release harmful substances.
Old, Damaged, or Cracked Dishes
Old, damaged, or cracked dishes should not be used in the microwave. These flaws cause the dish to break or shatter during heating, posing a safety risk.
Over time, these dishes harbor bacteria or lead to the leaching of harmful substances. Replacing old and damaged ones with new ones labeled microwave-safe is best.
Styrofoam is an expanded polystyrene foam product. They are used to make disposable coffee cups, coolers, and packaging materials.
Although some Styrofoam containers are labeled microwave-safe, it's best to avoid using them. This is because they release harmful chemicals when heated.
In addition, styrofoam is highly flammable. It will ignite or catch fire, posing a significant safety risk.
Mistakes People Make When Heating Food In The Microwave
Here are common mistakes people make when heating food in the microwave and detailed explanations on how to avoid them:
Microwaves heat food unevenly, resulting in hot spots and cold areas. To avoid this, stir or rotate the food halfway through cooking. For larger items, consider using a microwave-safe dish with a lid. You can also use microwave-safe plastic wrap to help distribute heat more evenly.
Using Inappropriate Containers
Using containers made of metal, aluminum foil, or certain plastics will cause sparks, melt, or release harmful chemicals. Always use microwave-safe containers labeled with the microwave-safe symbol.
Microwaving food for too long will cause it to become dry, rubbery, or burnt. To prevent overcooking, start with shorter cooking times and periodically check the food's progress.
Not Using Microwave-Safe Covers
A microwave-safe cover or vented lid helps retain moisture and prevent splatters. Avoid regular plastic wrap or plastic lids that are not microwave-safe.
Ignoring Standing Time
Due to residual heat, microwave food continues to cook even after the timer stops. Allowing the food to stand for a few minutes after microwaving will help to distribute heat evenly and complete the cooking process. Follow the standing time instructions provided in recipes or on food packaging.
Microwaving Whole Eggs or Sealed Containers
Microwaving whole eggs in their shells or sealed containers causes them to explode due to steam pressure buildup. To avoid this, add salt to the water before microwaving.
Not Adjusting Power Levels
Using the highest power setting for all types of food can result in overcooked or burnt dishes. Adjust the microwave's power level according to the type of food and desired cooking results. For example, use a lower power setting for delicate items like fish or custards and a higher setting for denser foods like potatoes or casseroles.
