They can be used safely in the microwave. When I received them, I filled one 3/4 full of tap water. I microwaved it on high bringing the water to a quick boil. I let it boil for 5 minutes. I emptied it and refilled it 3/4 full of tap water and brought it to a slow simmer like you would with soup. I let it simmer for 5 minutes. I emptied it and filled it 3/4 full of chicken noodle soup and brought it to s slow slimmer. All of that was with the same bowl and it did not fail. I have been using them ever since in the microwave heating and reheating soups, stews and gravies without any of them failing by coming apart at the seams. The reason I wrote this review is because I can see some potential buyers passing them up because of comments I see that they are not safe to use in the microwave. Those comments are not true.
