Can You Microwave Enamelware? Mugs or Dish and Bowl?

If you’re like most people, you probably have a few pieces of enamelware in your kitchen cupboards, but Can you microwave enamelware? In this post, we’ll take a look at the safety of microwaving enamelware and offer some tips for how to properly use it. Stay safe and enjoy your enamelware!

It’s no secret that enamelware is popular among consumers. It’s vintage aesthetic and variety of colors make it a popular choice for everything from kitchenware to camping gear. But can you microwave enamelware? The answer may surprise you. Read on to learn more about the safety of microwaving enamelware and tips for using it safely.

What Is Enamelware?

Enamelware is a type of pottery that has been coated with enamel. Enamel is created by combining water glass, sodium carbonate or limestone, and ground-up colored material such as kaolin, then heating the mixture to produce molten glass. 

The vitreous glass is applied to the surface of an object before it has cooled. After baking at a high temperature, the glossy enamel glaze takes on its final color and will not chip or crack over time.

Enamelware was first produced in Germany during the 1800s when Wilhelm Keil began making porcelain enameled steel goods. It quickly spread throughout Europe amongst manufacturers who desired both practical kitchen goods made from metal as well as beautiful pieces for display cabinets in homes. By the early 1900s, enamelware was being produced all over Europe and America.

Enamelware is still popular today and can be purchased for many different purposes: from cooking and baking to serving and displaying food. Enamelware can be used in an oven or on a stovetop; it does not absorb stains or odors as metal pots and pans do. 

It is dishwasher safe for convenience, though some manufacturers recommend hand washing their enameled products to prolong the beautiful luster of the finish. Enamelware continues to make its way into modern kitchens all around the world!

Can You Microwave Enamelware?

No. Even though enamelware is often touted as being microwave-safe, that is not entirely true. For example, certain colors of Fiesta dinnerware are only microwavable up to 400°F.

Enamel-coated cast iron is never recommended for the microwave because it is likely to completely shatter after heating even briefly in a microwave oven

Although most modern consumers use aluminum or stainless steel cookware, many brands of quality cookware are made with an enameled coating (a thin layer of glass baked on) over metal bodies (cast iron, carbon steel, or copper). 

Enameled cookware has several advantages: It does not corrode like unlined metal cookers; it conducts heat more evenly than unlined pans; it does not react to acidic foods as unlined pans do.

However, since enamel is a glass-based material, it is very susceptible to fracturing when exposed to sudden changes in temperature (like water that is hotter than the enameled pan). 

The high heat of microwave ovens can cause this type of thermal shock and will crack the enamelware. Similarly, placing an already hot dish into cold or vice versa can result in cracking or shattering of your ceramic cookware.

When choosing cookware for your microwave it is best to choose models with either tempered glass lids or made with materials that are safe for use in your microwave oven. It’s also recommended that you avoid cooking food containing large amounts of fat or sugar as this can cause your microwave to smell and the frequency of cleaning will be increased.

Some general guidelines: 

  • Do not use any cookware that has a chipped, cracked, or severely scratched surface;
  • If there is no visible damage but you’re unsure of its safety, do not use it. 
  • It is always best to check with the manufacturer directly before using your enameled pan in the microwave. 
  • If you cannot find contact information for your brand of cookware, it would be best to discard it.

Stainless steel and glass are perfect safe materials for microwave ovens because they do not get hot enough to induce thermal shock or breakage when exposed to microwaves while ceramic and porcelain buildups on metal parts may become toxic over time.

Microwave-safe cookware has a smooth, metallic surface that does not contain chips, cracks, or scratches. It is made of high-quality materials that will not crack or break when exposed to sudden changes in temperature. 

For your safety and convenience, choose microwavable cookware with microwave-safe glass lids. As an added measure, never use any type of cookware without consulting the manufacturer directly first for its microwaving specifications.

When in doubt about the suitability of any piece of enameled cookware, simply keep it out of your microwave oven.

What Happens If You Put Enamelware in the Microwave?

If you put enamelware in a microwave, then it may do strange things. Metal can reflect microwaves and cause sparks to fly or it might bounce around and get hot very quickly. If there is food in the oven when this happens, the metal could damage the microwave from inside by scratching or cracking its inner surface.

Can You Put Enamel Plates in the Microwave?

They are made of glass. No, you can’t. Enameled plates are just that: enameled. They’re not only glass, they’re glass with an enamel-like finish over it. 

Can you put them in the microwave? No, because microwaves work by passing through the glass and heating the food inside it by making molecules go back and forth very rapidly to create heat energy (the friction makes water molecules move faster). 

But since your plate is now covered with enamel, the microwaves cannot pass through easily anymore. You might as well try putting thicker glass or metal in there instead.

Can Enamelware Go in the Oven?

It depends on whether the type of enamelware is meant for use in the oven or not. Enamelware that can be used in the oven often has a label that says “oven-safe” and typically will say so on its packaging. 

Also, if it does not say that it is dishwasher safe, then you should avoid putting it in your dishwasher or you run the risk of scratching off some of the vulnerable glazes on the piece. 

If an enamelware item like a roasting pan where to get chipped, for example, this might allow rust to penetrate beneath the finish and make small holes; these holes would be places where water could sneak through and cause pitting.

Can An Enamel Mug Be Microwaved?

It is impossible to microwave any kind of enamelware in the microwave.

Enamel mugs are made through a process called fusion. Fusion is when two pieces of glass (or other materials) are heated and then fused. This creates the smooth enamel finish we know and love. Since microwaves heat food by moving molecules inside it, this means that if you try to microwave an enamel mug you will end up with a melted mess on your hands (and maybe in your face too)!

The reason for this is that microwaves are designed for use on more conductive materials. Things like aluminum or copper are excellent at being able to travel electricity throughout their whole object without wasting too much energy on things like insulation. 

The insulation used in low-quality mugs can cause the microwaves meant to heat the food to be reflected rather than absorbed into the mug. So instead of your food getting hot, you end up with a mug that gets too hot and then explodes (and maybe splashes scalding water onto your face… ouch).

How to Heat Enamel Mugs Safely?

You want to eat or drink something hot in your enamel mug, right? For this, you need somehow to heat it. But not all heating methods are safe for enamel mugs!

When are Enamel Mugs Safe to Use

Enamel mugs are safe if they are not scratched inside. Therefore, avoid using metal implements when taking food out of your enamel mug! Also, be careful with coffee mugs that have a glaze on the outside- this glaze can easily get damaged by rubbing against other rough objects (e.g.: other cups).

How do I Heat My Enamel Mug Safely

There are three ways to heat an enamel mug without damaging it: Put a few drops of water in the mug and put it in a microwave oven for a couple of minutes. Use a gas cooker or induction hob to heat your enamel mug. Build a fire, make sure the flames do not touch your enamel mug.

Enamel mugs are made from steel coated with other metals such as nickel and chromium(naturally present in clay). Therefore, they are very safe to use! Be careful when using other types of heating methods though- this might be risky if you have an old or cheap enamel mug that is not made out of quality material. (e.g.: used coffee mugs)

Can You Put an Enamel Pan in the Microwave?

No, you should not put enamel pans in the microwave. Enamel can break down when exposed to oven cleaners or very high heat. The same will happen if an enamel product is heated in a microwave for extended periods. 

When foods are microwaved, they heat very quickly. If an item absorbs this heat poorly it may become hot enough to cause the glass particles to melt and even explode. This is because the items are being cooked much faster than conventional cooking methods which allow pressure to build up inside them before they have a chance to cool down again.

 If there were chunks of food trapped inside that became superheated, steam explosions could occur when they “jump” due to thermal expansion as well as splattering acidic juices.

Enamel pans are typically not meant to be used over direct heat like on a stovetop. It is also possible for enamel cookware of any sort to break down when exposed to excessive amounts of very hot water or liquids. 

This can happen if normal use warps the pan, or if it cracks due to rapid changes in temperature (such as slowly heating an empty pan). For this reason, you should always fill your enameled cast iron with boiling water before using it for something like risotto.

Wash by hand with warm, soapy water and dry thoroughly after each use. Abrasive cleaning pads or scouring powders may scratch the surface which can result in chipping or cracking over time. Keep away from direct heat from stoves, open flames, or other sources of intense heat.

Is It Safe To Eat Off Enamel Plates?

Some people say that enamel plates are safe to eat off of. They reason that enamel is an inert or non-reactive material, so it does not pose a health risk. While the material itself may be inert, there are certain circumstances where using enamel plates can be dangerous.

For example, acidic foods can break down the surface enamel on dishes and cause metal contamination in food. Enamels are also sensitive to thermal shock, which means sudden changes in temperatures can cause them to crack or shatter while they are being washed or heated. 

The best rule of thumb when it comes to dealing with enamel plates is avoiding placing anything directly onto them if you want peace of mind about what you are eating.

When you purchase enamel plates, remember to check for cracks and chips on the surface of the dishes before they are used. If there are any cracks or chips on the surface, food can collect inside these fissures and become contaminated during use. Avoid using enamel plates that have visible scratches or pits as well, because these areas also collect food particles.

Enamel dishware may be convenient because it is easy to clean and very durable; however, it should only be used if its surfaces are completely smooth and free of any damage or contamination. 

You can protect yourself by avoiding placing anything directly onto these surfaces without a protective barrier like a paper towel or placemat underneath what you’re eating off of. It is best to limit enamel dishware use to decorative purposes instead of for actual food consumption.

To summarize, you should not allow your family members or guests to eat directly from any enamel plates that have visible damage or contamination. But if the dishes do not have any cracks, chips, scratches, pits, or contamination on them and you wish to use them for decorative purposes instead of eating off of them – they are completely safe to do so!

Frequently Asked Questions

  1. Is it safe to microwave enamelware?

No. Enamel cookware cannot be used in the microwave because of the possibility that it will become too hot and cause breakage or thermal shock. 

  1. Can you wash enamel pots in a dishwasher?  

Enamel pins are not dishwasher safe, but they may be washed with warm soapy water by hand instead. For stubborn food particles, choose a soft sponge or brush rather than an abrasive cleaning pad for your enamel pots and pans. 

  1. Can you put cast iron cookware on glass top stoves? 

Yes, but only if the pan is pre-seasoned first! If you do not coat cast iron with oil before using it on glass stovetops, the metal will react to the heat and damage your stovetop. 

  1. Can you use enamel cookware on induction stoves?

Typically, enamel pans are not compatible with induction cooking because there is no flat metal base on them. Enamel pots can be used for decorative purposes on an induction stove but should not be cooked directly.

  1. How do you clean enamelware? 

If food or liquid has gotten into cracks or crevices, soak the dish in warm water before scrubbing it out with a soft sponge or brush. Avoid using abrasive cleaning pads when possible since they can scratch up the surface over time. Also, avoid harsh chemicals especially oven cleaners because they will eventually destroy your pot or pan! 

  1. Is cast iron cookware safe to eat from? 

If the cookware has been thoroughly cleaned and seasoned, it is safe to eat from. Be aware that cooking with dirty or rusty cast iron cookware can cause metal poisoning if you ingest small amounts of rust in your food! 

  1. How do you remove a chipped enamel coating on a pan? 

Chipped pans should be thrown away because the damaged areas where chips have occurred provide an entry point for moisture and will eventually corrode the entire pot or pan.

Microwave ovens are not recommended because they get very hot inside, which may damage the enamel surface of plates or bowls. With regular use, enamelware becomes stained over time but these stains usually come out when using warm soapy water and a soft sponge or brush. A dishwasher can be used on enamel dishware, but only if the cycle is a gentle one. If you have an enamel pot with food particles stuck to it, soak it in warm water first before trying to clean it out. 

  1. Can you put aluminum foil on top of cast iron skillets? Yes or No? 

You can place aluminum foil or pans directly onto your cast iron cookware when cooking meat items like bacon; however, avoid storing leftovers in this same pan because acidic foods may cause the metal under the foil to come in contact with your meal and spoil your dinner!  

  1. Can you wash enamel pans in the dishwasher?

Enamel pots and pans may be put into a dishwasher but only if they do not have chips or cracks in them. If there is even one scratch on your pot or pan it will become damaged when cleaning because abrasive materials like sponges and brushes are used during the cycle. This will lead to rusted food particles making contact with your clean dishes and stained surfaces that are harder to scrub off.

  1. Can I use soap on enamel pots and pans?

It is recommended that you do NOT use any type of abrasive cleaning pads or sponges with enamel cookware since this will eventually lead to scraped-up surfaces that can let germs or pathogens into your dishes. 

Use warm water instead, just like the professionals! 

  1. Is it safe to put aluminum foil over cast iron skillets? 

Yes, but only if you also have an enamel coating on the pan itself because plain sheet metal will react with the aluminum foil and ruin your meal! If you are using a single layer of foil to catch your drippings during cooking, there should be no problem unless you have removed the protective outer coating.

Another good rule of thumb with plain aluminum is to keep it away from any high-acidic foods, like tomato sauce.

  1. What should I do if my enamelware has cracks?

If you see a chip in your pot or pan it will be best to throw the item out because moisture will get into the inner layers and lead to rusting or rotting that can get into your food. 

Also, avoid using harsh chemicals for cleaning because this also leads to damaged surfaces which may cause corrosion! 

  1. How do you clean enamel cookware? 

Scrubbing should be done gently with warm water and a soft sponge or brush without too much elbow grease. If there are stuck on food particles stuck, turn off your stove and soak the enamel dish before trying to scrub. 

  1. Can you put aluminum foil on cast iron skillets?

Putting aluminum foil over plain sheet metal is bad for your health and will quickly lead to damaged food so don’t do it! If you still think the foil is a good idea, be sure that there is no enamel coating on the pan or pot itself first because this will react badly with aluminum and leave stains on your dinner!


Can You Microwave Enamelware? It is not recommended that you microwave enamelware. Enamelware can tend to crack or shatter, which may lead to injuries if microwaved. 

Besides, for cleaning, the best way to clean your enamel ovenware is by hand with soap and water. If the cookware needs more than just this basic cleaning, then it might need professional attention from an expert to avoid any potential dangers of using it again without being properly inspected for cracks or other damage.
