The answer is yes that most ceramics can be microwaved and most ceramic and porcelain baking dishes are microwave safe, but you should make sure it is labeled “microwave safe.”

It isn’t a good idea to put gilded ceramic plates in the microwave. Gold powder or dust can melt and contaminate food.

Also, putting metal in the microwave is dangerous because the waves will bounce off the metal and damage the microwave oven. So, always read the manufacturer’s instructions to keep yourself safe and to make sure you can use the microwave for a long time.

In general, ceramic dishes are microwave-safe as well as microwave-safe ceramic bowls. in other words, ceramic items are generally safe for use in microwaves as long as they’re not painted with lead-based paint. If you do use a ceramic plate in the microwave, it’s best if you place something between the dish or mug to prevent splatters. Also, make sure not to heat up food for too long as this may cause the ceramic to crack or break.

Important notes to avoid cracks when using the ceramic microwave

Here are the notes you need to remember to avoid breaking the dish when microwaved

  • When preparing or serving food, it is important to consider the temperature. Putting something hot on something cold can cause leaching of chemicals and toxins from the container materials. Therefore, when possible, always reheat foods to help maintain the proper temperature levels and reduce the risk of contamination.
  • Don’t put hot food or drinks in cold pottery, and don’t pour boiling water or hot drinks into it.
  • In the same way, don’t pour cold water into a hot ceramic dish.

How do ceramic dishes get made?

Most of the time, clay is used to make ceramics. The clay is shaped and molded, just like any other kind of pottery.

There are many different kinds of ceramics, such as brick, earthenware, and porcelain (or china). Most dishes are usually made of ceramic.

First, the clay is shaped, and then it is fired at a very high temperature to harden it. When the material is heated, it gets harder and stronger, so it can last for a long time.

Most ceramics can be heated in a microwave, but there are a few things that can’t.

Procedure to check a ceramic dish before putting it in the microwave

First, please check to see if “microwave safe” or are typically microwave-friendly as long as they don’t contain metal in any shape or form. Look for three wavy lines instead. This means that the product can be heated in a microwave.

Pour three-quarters of the water into both the microwave-safe mug and the empty ceramic pot you want to test.

Put both containers in the microwave and heat them for one minute on high.

Take them out of the microwave using a potholder or oven mitts.

If the water is hot and the ceramic pot is cool or warm to the touch (be careful! ), you can microwave this dish and it is ceramic microwave safe

If the ceramic dish is warmer than the water inside, it is not safe to microwave.

In another test, there is no water used. Put the unmarked ceramic in the microwave and heat it for 20 seconds on high. If the dish gets hot to the touch (be careful), it is not safe to microwave it.

The answer depends on the material the ceramic item is made of. If it is made of a porous material that can soak up more than 10% of its weight in water, you can’t microwave it for more than a minute.

If the ceramic is made from pure clay that absorbs less than 2% of its weight in water, you can safely microwave it for a few minutes.

Lastly, ceramic dishes that have metal decorations or are glazed with lead should not be put in the microwave.

Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.

Pottery and ceramics are both terms for things made from clay that has been shaped and baked in a kiln. Including sculptures and ornaments, but here we’re talking about clay dinnerware and kitchenware.

The kind of clay used to make a piece of ceramic defines what kind of piece it is. The best china is made from finer, more pure clays. Less refined clay is rougher, more plastic, and has more minerals mixed in.

Most of the time, the finer ceramics are fired at higher temperatures, which makes them more vitreous, or glassy, and better for the microwave. The ones that aren’t as smooth and are fired at lower temperatures are often too porous and fragile to be used in a microwave.

Below are the different kinds of ceramics in order of how porous they are and we tell you if they’re likely to hold up to microwave cooking or not.
  • Most earthenware is fired at low temperatures and has a lot of holes, so it can’t be used in a microwave. Also, the low firing temperature lets a wider range of pigments be used in the glaze, some of which can be affected by temperature.
  • Even though it is made from more refined clay and fired at higher temperatures than earthenware, mid-fire stoneware still has a lot of the same qualities that make it unsuitable for use in a microwave. It is also best not to cook with it in the microwave, but it can be used to heat up food in the microwave.
  • High-fire stoneware is usually glassy and can be used in the microwave.

Ceramic mugs can generally be used safely in a microwave, however, it’s important to double-check the label before using. Ceramic is an excellent material for microwaving as it is non-porous and cooks evenly.

However, if the mug has any metal elements, such as a metallic handle or trim, these should not be placed in the microwave, as they can spark and cause a fire. If in doubt, it’s best to check with the manufacturer before microwaving.

Remember that ceramic mugs may become very heating in the microwave, so always use oven gloves or tongs when removing your mug from the microwave. Also, allow the mug to cool down before handling, as ceramic may become very hot and cause burns.

FAQs: Is ceramic microwave safe? How to check if a ceramic dish can go in the microwave?

Which is better for microwaving glass or ceramic?

A microwave will heat ceramic dishes faster than glass dishes. Even though your food will still cook in a glass bowl, glass takes longer to absorb and release heat than ceramic.

So, ceramic plates will get hotter faster, but glass will let you watch your food cook and see how it’s doing.

What shouldn’t you put in the microwave?

Steel, iron, copper, and other hard metals should never be put in a microwave, nor should anything made of or containing them. Metal surfaces reflect microwaves, which makes the appliance hotter inside and could cause a fire.

Can you put glazed ceramic in a microwave?

Some ceramics can be put in the microwave and some can’t. It depends on how much and what kind of metals are in the clay and glaze, as well as how strong your microwave oven is. Only by putting each piece in the microwave can you be sure. Put water in it and microwave it for 30 seconds at a time.


As you can know that is ceramic microwave safe. Besides that, If you need to quickly check if a ceramic dish is microwave-safe, here are three ways to do it: look for the label, test with water, or use the touch test. If you don’t have time to do any of those things, it’s generally safe to assume that the answer is no – err on the side of caution and don’t put it in the microwave.
