You may have heard that you cannot microwave ceramics. But how exactly do microwaves work? Microwaves are electromagnetic waves that don’t care what’s in their path. They will heat whatever they can get their hands on. The issue with placing pottery in the microwave is not the microwaves themselves but rather the uneven heating of your dish.

It is possible to microwave pottery, although it is not advised. Microwaves might melt the glaze and make a mess in your microwave. If you’re going to microwave pottery, be sure it has a heat-resistant glaze or is composed of stoneware.

You don’t want to destroy your beloved dishware by microwaving it; therefore, always know what sort of dishware you have before microwaving it.

When microwaving dishes with glazes, use caution since the high temperatures may cause them to melt.

Is it safe to microwave pottery?

Pots can be microwaved. However, it’s vital to remember that glazes change at high temperatures. Thus, some may not be suited for cooking. The most dangerous are pots with leaded glazes. However, if your dish has a leaded glaze or other chemicals, do not wash it before warming it up since heat will release any harmful vapors into your house.

It is typically safe to microwave your pottery, but like any other material, pottery has restrictions. For example, the ceramic is breakable and may shatter if the temperature suddenly changes.

The glazes used on ceramics might include dangerous compounds that produce fumes when cooked in your microwave. All of these gases will be absorbed by the clay and minerals in the clay, potentially harming you in the long term.


  • Check the label: Before using a dish or mug, search for a “microwave safe” label, which is usually placed on the bottom of the ceramic mug or dish; it may be any indication or just two parallel lines. Then, when you purchase it, you may check the package to see whether it is microwave safe.
  • Test the unlabeled dishes: Sometimes, a clay dish does not have a label, and you are unsure how to determine whose brand it is. In such a scenario, you must fill a microwave-safe cup and the cup you wish to test with water and microwave them for 1 minute. After a minute, pull both of them out and touch them to see if there is any difference; if there isn’t, you may use the cup without concern.

Take care not to microwave cold storage containers or plastic packs. These foods are intended to be kept refrigerated and should not be heated.

Is it safe to handmade microwave pottery?

Handmade ceramics can be microwaved! Take special care to avoid fractures and chips in the pottery and utensils. Before cooking, place it on a microwavable safe surface, such as a ceramic plate.

Organic clay is known to be microwaveable due to its porous nature and lack of radioactivity, while others argue that this isn’t true for recently burnt products.

Ceramics with extra glaze may be metal detectable (check to see whether your cookware was made with copper, iron, or lead), but this will typically rely on whether an additional coat of glaze or lacquer was applied.

You may be wondering how to put the ceramics to the test. Here are various methods for administering the exam.

  • Fill with water: Pour some water into the pottery to see whether there is any leaking. If there is no leaking, place your handmade pottery on a plate and microwave it on high for 1-2 minutes.
  • Touch test: After placing the handmade pottery in the microwave, remove it using oven mitts and examine if it is hot or not; if the cup is warm but the water is cold, the cup is not microwave-friendly.
  • Label: Always use a label or a permanent pen to keep track of your microwave-friendly plates. Try to mark the bottom of the plate with whatever emoji or shape you choose to make it easier to recognize.

Materials that cannot be microwaved may easily break, melt, or damage the microwave. They not only introduce harmful chemicals into the meal but may also create fires. Therefore, it is always best to inspect the dishes before using them.
