Is condensation between the glass in microwave safe?

No, condensation between the glass in a microwave is not safe. Condensation is the process by which water vapor turns into liquid water, and it can cause the glass to become weak and break under the heat. Additionally, the water can interfere with the microwaves and cause the food to cook unevenly. For these reasons, it is important to ensure that there is no condensation between the glass before using the microwave.
