Reasons why you Should Avoid Microwaving Enamel Mugs

Enamel mugs are made of materials that should not be microwaved; the mugs could crack, there will be high power consumption, and your microwave could be damaged in the process.

Below is a detailed explanation of the reasons mentioned.

  • Enamel mugs are made of materials that should not be microwaved

As stated earlier, enamel mugs are cast iron or steel dipped into enamel liquid. Metals should not be placed in the microwave. Metals cause an arcing reaction, an explosion, and bring about an accident or the cracking of the mug.

  • The enamel mugs could crack in the microwave

Despite the fact that the enamel mugs can survive oven and open fire heat, they cannot handle microwave heat. The heat from the microwave becomes unbearable for them, leading to cracks and making leakage cracks in the mug.

  • The microwaving process will be slowed down

The different layers of the materials used to make the enamel mugs and the shiny enamel coating slows down the penetration of rays of the microwave into the mug’s content. The mug’s surface begins to react by deflecting the microwaves, making it impossible for the beverage in the mug to get heated as quickly as it should.

  • Increased power consumption

Since enamel-coated mugs slow down the microwaving process, more power and time will be required for the microwaves to penetrate the mug’s outer surface and get to your beverage. Suppose you microwave the beverage without putting a lid on the mug; the beverage will be heated unevenly.

Heat will only get full access through the top opening part of the mug while the rays struggle to penetrate the rest of the parts.

  • Microwaving enamel mugs may damage your microwave

Suppose you place an enamel mug in the microwave, and due to high heat, the mug cracks and begins to leak. The beverage may flow and begin to spread into delicate parts of a microwave that you can hardly reach even if you decide to clean your microwave thoroughly. The liquid may cause serious damage to your microwave after getting in contact with these electric parts.

Can You Microwave Enamel Mugs?Yes, enamel mugs can hold boiling water. The materials used in manufacturing the mug ensure it is durable and capable of handling high heat temperatures. Only microwave heat has proven to be too much for the enamel mug.
