The Microwave Safe Symbol on a Mason Jar
Microwave ovens are a convenient way of heating or reheating food. However, using glass containers in the microwave does come with certain risks, such as breakage or exploding. To avoid these risks, it’s important to check if the Mason jar you’re using is safe for use in the microwave. Most Mason jars have a microwave safe symbol printed on them; it can be a sign of waves or the words “microwave safe.”
| Symbol | Meaning |
|---|---|
 |
The wavy lines symbol indicates that the Mason jar is safe for microwave use. The container has been manufactured with materials that can withstand the microwave’s high temperatures. |
 |
The unsuitable symbol indicates that the jar should not be used in the microwave, as it is made with materials that are not microwave safe. |
It is important to note that while Mason jars have a microwave safe symbol, some experts advise against using glass containers in the microwave altogether. It’s always best to follow guidelines and warnings provided by the manufacturer to avoid any unnecessary risks.
What does the microwave safe symbol look like?
Microwave safe symbols are usually printed on the bottom of containers. This symbol is essential in identifying whether a container is safe to use in the microwave or not. The symbol is an image of a microwave oven, with wavy lines moving from the top to the bottom of the oven. The wavy lines depict radiation, a form of electromagnetic energy, that is absorbed by food and heats it up. The presence of this symbol guarantees that a container will not cause harm to the microwave or the food inside.
The Meaning of the Microwave Safe Symbol
- The symbol indicates whether a container is safe to use in the microwave or not.
- Microwavable safe containers have been tested and approved by the FDA.
- The symbol guarantees that the container will not release dangerous chemicals into the food or harm the microwave.
Misconceptions about the Microwave Safe Symbol
There are many myths surrounding the microwave safe symbols that have been debunked. For example, some people believe that plastic containers release harmful chemicals when heated in the microwave. However, microwavable containers have been tested for their safety, and their plastic composition ensures that they do not melt or release toxins when heated. The microwave safe symbol guarantees that a container has been tested and approved to be safe for use in the microwave.
Another misconception is that containers with a symbol depicting just a fork and a plate are microwave-safe. However, this symbol only means that the container is safe for food contact but not necessarily safe to be used in the microwave. Always look for the microwave safe symbol when choosing which container to use in the microwave.
The Importance of the Microwave Safe Symbol on Mason Jars
The microwave safe symbol is important, especially when using mason jars in the microwave. While mason jars are great for storing and preserving food, not every mason jar is safe to use in the microwave. It is essential to look for the microwave safe symbol on the bottom of the jar to avoid any damage to the container or the microwave. Mason jars with a microwave safe symbol guarantee that they have been tested and approved and can be used safely in the microwave without causing any harm or damage.
| Microwave Safe Symbol | Description |
|---|---|
 |
This symbol indicates that the container is safe to use in the microwave oven. |
 |
This symbol indicates that the container is not safe to use in the microwave oven. |
It is also important to note that even if a mason jar has the microwave safe symbol, it should not be used in the microwave with the lid on. The lid traps steam, which can lead to pressure buildup and potentially cause the container to explode, leading to harm and damage.
Factors to consider before using Mason jars in the microwave
Using Mason jars in the microwave is a convenient way to cook or reheat food. However, before microwaving food in a Mason jar, there are certain factors to consider to ensure safety and avoid damage to the jar.

- Liquids: When heating liquids in Mason jars, be aware that boiling may occur, which can cause the liquid to expand rapidly and the jar to crack or break. To prevent this, it’s best to leave a little space in the jar for the liquid to expand.
When using a Mason jar in the microwave, it’s important to exercise caution and pay attention to the factors listed above. Additionally, here are a few tips to keep in mind:
- Always remove the lid or any metal components before microwaving a Mason jar.
- Heat the Mason jar in short increments to prevent overheating. Stop and stir the food or liquid frequently.
- Allow the Mason jar to cool before handling it. It can be very hot to the touch after microwaving.
