About Microwave Safe

A microwave oven heats or cooks food very quickly using short electromagnetic waves, namely, microwaves. In most cases, the microwaves heat the water content of the food. However, in some cases, the microwaves concentrate on the carbonized (burnt) parts of the food, causing the temperature to rise higher than the other parts. For example, the microwaves concentrated on the carbonized (burnt) parts of stir-fried vegetables can create a large temperature difference in /on the tableware item, which may cause breakage. In addition to water content, oil content is also heated. The oil has a higher boiling point than the water, so it heats up at a higher temperature, creating a very large temperature difference between the parts that contain oil and the parts that do not, which can cause breakage.

・Never soak hot tableware in water or place it on the cold kitchen counter. Avoid rapidly heating frozen foods or putting [the cold tableware just taken out of the refrigerator] in the microwave. A rapid change in temperature will lead to “crazing” (chaps) or breakage.
