How safe is your ceramic ware to use in the microwave? If you’re wondering, you’re not alone. Microwaves are a huge part of modern life and you’ll probably want to continue using your favorite mug or dish as long as possible, as long as it’s safe, right?! Here I look at whether your ceramic items are microwavable or not. What properties make it safe. What to look for and why some ceramics are a ‘no no’.
Microwave cooking saves time and is a convenient way of preparing meals, including healthy ones. There are do’s and don’ts with microwave cooking and I’ll start with my list of these before moving on to the deal with using ceramics in the microwave.
Do’s and don’ts – microwave Cooking
- Do use a microwave-safe dish or container, even with ceramic
- Don’t use aluminum foil in the microwave
- Do cover food with a lid or microwave-safe food wrapping to prevent splatters and spills
- Do check that the dish is rotating properly to ensure even cooking
- Do use the right amount of time – don’t overcook your food!
- Do stop and stir the contents
- Do use recipes designed for microwave cooking
- Do NOT heat eggs in the microwave while they are still in their shells.
Don’t place anything metal in the microwave – this includes aluminum foil, knives, forks, spoons and the like, as these will produce sparks when heated in a microwave.
Remember that microwaves heat up food from the inside out, so always stir your food halfway through cooking time.
Be careful not to overcook your meal – if you see steam coming off of it, take it out of the microwave right away!
Keep an eye on your food while microwaving so that you don’t accidentally over-cook it. If you want to reheat something quickly, try putting it on high power for 10 seconds at a time.
There are two ways to make eggs safe for microwaving: either break and scramble them in a microwave-safe bowl, or prick the yolks with a toothpick before cooking.
Always use an oven mitt when removing your dish from the microwave – never try to grab it by hand!
Why use ceramic for microwaving?
Products made of ceramic are usually durable, non-porous, and can withstand high temperatures. Hence why people like to use ceramic, including for microwave cooking.
Microwaves use electromagnetic radiation in the microwave frequency range to heat and cook food. This is dielectric heating or radio frequency heating. With this type of heating, you can’t use metal containers as they will spark and damage the appliance.
That leaves plastic and ceramic (or porcelain, stoneware, or pyrex) containers, which are more environmentally friendly than their plastic counterparts.
Dishes made of fired natural materials, such as ceramic, won’t emit harmful chemicals when heated.
And, ceramic doesn’t stain like plastic microwave containers do, nor will they blister and flake.
When not to use ceramic cookware in the microwave?
Do all types of ceramics work well in a microwave oven? No, not at all. Play save and don’t use ceramic cookware or containers in the microwave that have metal parts, such as a handle or lid of steel or aluminum, or metallic trim, e.g. gold or silver embellishment. Ceramic nonstick pots should definitely not go in a microwave because they have metal bases.
Ceramics with certain glazes should not go in a microwave. Though food containers are excluded, a lot of ceramics have a type of glazing that contains lead. Thus, avoid any ceramic containers that are not food grade items.
- Don’t use containers with metallic trims or parts metal parts
- Don’t use ceramic containers that are not food safe
- Don’t use ceramic nonstick pots or dishes in the microwave
How do I know if my ceramic cookware is microwaveable or not
Is Ceramic Cookware Safe to Use in the Microwave? Look for the microwave safe symbol that indicates your container is good to go in the microwave. This symbol is usually a series of wavy lines, sometimes shaped as an ‘M’. It can be a square or a round symbol. It can differ depending on the product and country where sold.
Microwave safe symbol
You’ll generally find the microwave-safe symbol stamped on the bottom of ceramic items that can go in the microwave. It’s important to check for this before microwaving. The stamp might just be wording “microwave safe”, which is okay too.
Ceramic containers, including mugs and plates, that are microwave safe are typically labeled as such to avoid confusion in kitchens where there may be mixed sets of cookware.
If you don’t see any indication that a dish can be used in the microwave, then err on the side of caution and avoid using it in the microwave unless you find relevant information on the manufacturer’s website.
Reasons to use 100 ceramic cookware
A 100% ceramic pot or dish contains no metal. It will not cause sparks when heated up and can therefore be used safely in a microwave.
- Cookware with a natural glazed finish also looks nicer in your kitchen than traditional microwave dishes made of plastic which are prone to scratching, scuffing, and chipping.
- Ceramic cookware can last for decades if treated properly.
- Ceramic dishes are versatile. If you’re cooking rice in the microwave, for example, the dish can go from being microwaved to serving at the table. And then the left over rice can be refrigerated in the same dish.
- Ceramic cooking surfaces are naturally stain-resistant and resist bacteria, helping to keep you healthier.

My favorite risotto recipe for the microwave — Mushroom Risotto:
- 200g risotto rice,
- 1 1/2 cups water or stock,
- 1/2 cup milk,
- 7 oz (180 g) mushrooms,
- 2 eggs,
- 1 chopped onion,
- 2 oz (50 g) frozen peas,
- 4 oz (100 g) grated cheese,
- and salt and pepper to taste.
Add all ingredients to a good-sized microwavable ceramic pot and mix well. Put the bowl in the oven and cook covered for 5-10 minutes. After cooking stir and let sit for another 5-10 minutes.
You may have to adjust the timing to suit your microwave.
Does ceramic get hot in the microwave?
Ceramic pots or dishes can absorb heat in the microwave and so can get hot to touch. It depends on what you are cooking and the duration as to how how they may get. It’s always a good idea to handle heated cookware with dry potholders or oven mitts when taking them from any oven.
Why are some ceramics not microwave safe?
Some ceramics vessels have glazes containing lead and are not safe to use with food as the lead can leach into food during microwaving.
Is a ceramic mug microwaveable?
Not all mugs are microwaveable but you can put ceramic mugs in the microwave if it says so on the bottom or online. The mug is heated from all directions and not just the top.
Can ceramic plates go in the microwave?
Use ceramic plates if they are labeled as being microwaveable. Ensure that there is no metallic trim around edges.
