What Happens If a Plate Is Not Microwave Safe?

Well, you would be putting yourself in danger if you do not use microwave safe plates. Using paper or metal plates in a microwave is the most dangerous thing to do. The metal would spark which would result in a fire. The same goes for paper plates. So ensure that you do not use metal or paper plates in a microwave.

Also, if you want to place a plastic plate in the microwave, make sure that it has the word “Safe” on it. The “Safe” stamp means that it has been approved by the FDA so you don’t need to worry. However, if you do not see the “Safe” stamp on it, do not use it in the microwave. Since plastic plates have chemicals, it will seep into your food when microwaved if it doesn’t have the stamp. It could also melt and ruin the microwave.
