Additionally, soaking a clay dish in water before using it in the microwave can help reduce its porosity and minimize the risk of it becoming hot.

Size and Shape

The size and shape of a clay dish can play a significant role in its heating properties when microwaved. Generally, thicker and larger clay dishes have a greater ability to absorb microwave energy and retain heat. This can result in these dishes becoming hotter when microwaved compared to smaller or thinner dishes.

When a clay dish is placed in the microwave, the electromagnetic waves emitted by the appliance interact with the minerals in the dish’s composition. The larger the dish, the more minerals there are for the waves to interact with, leading to increased heat absorption. Similarly, a thicker clay dish provides more mass for the heat to be retained, causing the dish to become hotter.

It’s important to note that the heating patterns may also vary based on the shape of the clay dish. For example, dishes with curved or irregular shapes may experience uneven heating, resulting in certain areas becoming hotter than others. This is due to the way electromagnetic waves interact with the dish, causing variations in heat distribution.
