Can You Microwave Wood? Bowl or Skewers?

Can You Microwave Wood? This is a question that many people have wondered about, but not many know the answer to. 

In this blog post, we will explore whether or not it is safe to microwave wood and the potential dangers of doing so. We will also provide some tips on how to properly microwave wood if you decide to give it a try. Stay tuned!

Can You Microwave Wood

Types of Wood Utensils and Containers 

Here are some types of wooden items that you might see frequently:

  • Woven wooden plates and bowls
  • Wooden cups
  • Wooden cutlery
  • Wooden spoons and utensils

Wooden platters, bowls, and other containers are made by cutting a piece of wood in the correct shape or carving it using “green” (not kiln-dried) lumber which is softer than dried lumber and will not crack when shaped for use as a plate or bowl. 

Cutting boards, trays, and rolling pins can also be cut from green lumber to make cutting food easier on both knives and surfaces while preventing damage to either surface from the knife-edge itself without having to use a dedicated “cutting board”.

Wooden spoons are created by carving them out of green lumber with a sharp knife or chisel. Whittling is the process where people carve wood into objects using only a pocket knife. 

Wooden utensils were used hundreds of years ago before metal pots, pans, plates, and eating utensils became commonplace. Although some people still prefer wooden plates over their metal counterparts today due to concerns about chemicals found in metal plates leaching into food. 

Disposable wooden cutlery can be carved from wet green lumber using a sharp hand saw because it will dry flat without cracking along the cut line like kiln-dried wood. 

Using green lumber is cheaper than buying kiln-dried plate ware because it will warp and split within a year or two instead of decades like wooden plates that are not exposed to heat.

What Happens If You Put Wood In The Microwave?

Wood contains water, so when microwaves are absorbed in the wood, the water inside it is turned into steam. 

If too much steam is created, it can rip apart the fibers which hold the wood together. This causes small explosions in the wood cell walls and releases gasses that create what you see when you microwave a piece of wood; namely flames and smoke.

And there’s no need to worry about your microwave exploding. Wood only catches fire above 150°C (302°F). Microwave ovens heat food at around 120°C (248°F). Even if you do put wood in your microwave accidentally, there’s no reason for concern. The worst thing that could happen is having to clean up some spilled sawdust.

Can You Microwave Wood?

Yes, Wood is usually considered safe to heat in a microwave, but some types of wood may produce flammable or toxic gasses when heated. The type of gas produced will depend on the type of wood.

  • Wooden spoons and cutting boards often go into a microwave oven for cleaning purposes. The high temperature required to kill bacteria should quickly dry out any water leftover from washing, leaving the wooden spoon or cutting board completely dry and ready for use again next time you cook. 
  • Microwaving spatulas made from wood do not cause them to catch fire as long as they don’t contain any plastic components that melt at a lower temperature than the melting point of wood (typically around 190 °C). However, microwaving wooden chopsticks may cause them to catch fire.
  • Microwaving an empty cup or bowl made from dark wood may damage the microwave oven itself due to arcing between the cup and the metal walls of the interior of the microwave oven. Other materials used in wooden cups and bowls, such as plastic laminates, will not produce sparks while being microwaved unless they contain some iron content.
  • Some hardwoods tend to off-gas while being heated due to the presence of resins within them, which sometimes react violently when exposed to high temperatures. This can result in a build-up of flammable gasses that ignite into flames once the air is introduced into the mix. 
  • Examples of species of wood that have been reported to produce flammable gasses include Liquidambar, Black Cherry, flowering dogwood, black locust, mulberry, water locust, and paulownia. – Other types of hardwoods may emit fumes that are toxic when microwaved.
  • Examples of these species include Boxelder, camphor wood, cryptomeria, cypress, eucalyptus, fir, hemlock, juniper, koa, larch, spruce (Picea abies), redwood (Sequoia sempervirens), sweetgum (Liquidambar styraciflua), and western red cedar. 
  • Furthermore, certain species of pine (such as Eastern White Pine, Red Pine, and Mugo Pine ) may sometimes emit formaldehyde vapors when microwaved.  
  • Microwaving wooden chopsticks usually only produces sparks from the tips if they are made from wood that contains components capable of producing flammable gasses, while microwaving an empty cup or bowl may cause arcing between the cup and metal walls on some models of microwave ovens which can damage them. 
  • Wooden cups that contain some darkening agents may become hotter than normal while being microwaved, but this is usually a harmless effect. – Wooden spoons and cutting boards can be used to safely clean all sorts of kitchen surfaces, including non-stick pans if microwaved together with a solution of 10% dish soap in water.

It is very difficult to predict if a particular type of wood will contain components that are capable of producing flammable or toxic gasses while being heated in the microwave oven.

If you choose to test out whether your wooden cookware can safely be used in a microwave oven, it is best done on an individual basis (i.e., one spoon/cutting board at a time) rather than testing multiple pieces of the same species all at once since some species that did not produce a flammable gas in one test may produce a dangerous gas in another.

It is recommended that wooden spoons and cutting boards be placed near the back of the microwave oven rather than at the front since there should be little risk of any item catching fire if it fails to produce flammable or toxic gasses when heated.

How Long Do You Microwave Wood?

It is common for microwaves to ignite the wood, which then smolders for several minutes. How long does this smoldering take? What kind of damage is caused?

The microwave oven typically takes about 10-30 seconds to ignite the wooden kitchen match stick (5cm) and about 1 minute for the wooden board (10 cm). The length of time it takes will depend on how dry or wet the wood was before it was put in the oven. 

If you are trying to light your stove top with a match, instead of using one of your wooden matches try using an unused butane lighter as they will quickly burn just like disposable propane or butane stove. You can also use wax tarts. They last a long time!

The fire didn’t create a lot of heat; it started because the tip was touching the side of the oven. Some wood can smolder all day, burning very little and releasing noxious gasses. 

When microwaving wooden items like toothpicks or matches, do not use any metal objects such as silverware to remove them from the microwave (metal heats up and causes an electrical short which isn’t too healthy).

If you used lighter fluid after microwaving your match, there may be fumes in your kitchen still. Ventilate for 30 minutes before lighting any candles or using your stove top until it has aired out well. 

Anytime you use anything in your microwave including spray starch – there may be lingering fumes that could set your stove top on fire.

Can a Wooden Bowl Go in The Microwave?

Yes, but it may not be microwavable. Some wooden bowls are made with a microwave-safe finish, but if they have never been used in one you can’t assume it is okay to use them. 

If the bowl gets hot or starts to smell funny then don’t use that specific bowl in your microwave ever again. 

You can check to see if the wood has been treated by microwaving food in it for 1 minute at a time. After each minute take the temperature either with an approved food thermometer or infrared thermometer. 

If the temperature is hotter than 140 degrees Fahrenheit for more than 5 seconds then do not use that bowl. No matter how much you would like to reuse it, get rid of it and buy a new one.

Microwaving can be very dangerous and should not be attempted by those who do not understand the risk involved. If you would like to read more information on microwaves and how they work you can check out this article.

How Do You Know If the Wood is Microwave-Safe or Not?

There is no easy and straight answer to this question. The general assumption behind microwaving food in a container made of wood or any porous materials is that the material will absorb liquids from the food or steam from cooking [which can make it unsafe]. This is why you should never microwave using a wooden cutting board, but ceramics are okay. 

In other words, there is no guarantee. It depends on how much liquid/steam has been absorbed by the wood over time, which means you cannot rely on assumptions, only experience tells whether a certain type of wood container might be safe for your microwave oven. Here’s what we know for sure:

Wood does not catch fire in a microwave because it doesn’t get hot enough. It’s a myth! The only real danger comes from steam build-up and the risk of hot food splatters or spillage.

For example, if you want to microwave on a wooden cutting board, be sure to cover it with a microwave-safe plastic lid before popping it into your oven. 

If you’re microwaving food in a wood bowl or dish, don’t leave the microwave door open any longer than necessary, this will help reduce the risk of food spillages. In other words: do not put it in unless you intend for it to go straight from regular use onto the plate/bowl/whatever you are going to eat from.

Wood can affect the taste. This is why people generally prefer using glass or ceramic instead of wood when it comes to cooking, especially over longer periods.

The heat that ceramic or glass containers emit is more even than the heat that wood emits which means food might get burnt faster. 

How to microwave food in wooden container:

Step 1: If you want to microwave it in a wooden container, test it first with water before using it with food. 

Step 2: Put some water in the container and pop it into the microwave oven for 1-2 minutes. 

Step 3: Then let the container cool down to room temperature and give it a try – does it feel warm? It should only feel slightly warmer than your wrist/arm/etc. 


  • Do not leave it in there too long! If you are satisfied with this, then you can use your wooden bowl or dish for microwaving purposes without worry. 
  • Do not use a wooden container with wet food! The steam will get trapped inside and make the wood eventually unsafe to use in the microwave.

The material of your dish or bowl is not as important as what you put it in. Don’t let anyone tell you that microwaving a certain type of dish or bowl is safe. It’s not! Microwave-safe does not equal “microwave-proof”, no matter how new it might be.

For example, some people have tried putting metal bowls into their microwave oven without problems, only to accidentally heat something using a metal spoon, which then led to sparking/sparking sounds coming from their oven.

Labels on Wood

You might wonder how to determine if your items can be microwaved. The simple way is to look for them. the microwave-safe label on the bottom. If you can not find it, just try to look at the packaging.

Most of the products that we use in the kitchen, including dishes and containers for storing food in the fridge, usually also bear a symbol with a microwave oven or a microwave plate next to it.

Of course not all items that bear this symbol are safe to be placed in the microwave. For example, if you notice that your labels are printed on anything other than paper, such as ceramics or plastics, they may not be microwaves friendly.


Safety Tips For Microwaving Wood?

Wood can begin to smolder and produce smoke if it is microwaved. Be careful not to microwave any type of wooden item, including kitchen utensils or other items that have spills inside them which may cause the wood to ignite. 

If you choose to heat your food in the microwave using a wooden surface, make sure that the area is well ventilated so that airborne embers do not cause an issue. Also try placing your food on cork trivets, glass plates, or ceramic dishes before attempting to heat them in the microwave.

  1. Be careful about what kind of wood you use for cooking at home.

The only time you might see something similar would be at a BBQ. It may be dangerous to use wood from the garden shed because of fungus, termites, and other pests. The varnish on a wooden spoon could give off toxic fumes when heated in the microwave.

Wood should not be placed in a microwave or used to cook food. Wood has been known to catch fire when microwaved. When you heat your food it causes pockets of steam that get trapped inside the wood and cause it to heat even faster than before causing it to ignite. 

You can also get wooden utensils with metal handles so there is no need for concern about using them in the microwave ever again! No matter what kind of utensil you use, always look for things like this before putting them into your microwave.

  1. Be safe and always check the utensil before using it!

Wood is a natural material that can easily catch fire when microwaved. This is especially true of wooden objects that have been treated with chemicals or varnish to enhance their appearance. Another safety tip for microwaving wood.

When you microwave wood there always comes a time when pockets of hot air trapped inside cause the outside layer to heat faster causing a smoke-filled “explosion”. 

Never trust a wooden spoon or fork, they are more dangerous than you think! Wooden spoons splinter and leave slivers behind from being heated in the microwave, so try using another kind of kitchen utensil instead! 

There’s nothing safer than stainless steel! If you do not want to use plastic or metal utensils, there are other options such as glass and ceramic use.

If you choose to use a wooden spoon or another type of wooden item in your microwave, be sure that the item is completely dry before placing it into the microwave, and never attempt to use items that have any liquid inside them. 

Always follow the instructions that come with your microwave regarding how much wattage is needed and what types of objects can be microwaved. If you decide not to listen to this warning, put at least two layers of paper towel underneath your wooden object when heating it!

Can You Put Wood in The Oven?

You can put wood in the oven for drying out, but if you do you should not set it for more than 450 degrees Fahrenheit. If the oven is hotter than this and you put wood inside it will catch fire and burn rapidly.

If not already damaged by heat, the door of an oven could be made to burst open by a large quantity of wood-burning at once, which would probably cause a serious accident or fatality. In other words- don’t try it!

Can You Microwave Bamboo?

In the market, you can find bamboo plates that are specifically designed to not be microwaved. They typically say “Do Not Microwave” right on the packaging. If a plate is too thin and flimsy, it might catch fire in a microwave oven if placed over a strong heat source for an extended period. 

Plates made out of organic bamboo fibers or recycled paper pulp do not have this risk as they will easily break up into their natural components (organic matter) when exposed to heat like that found in a microwave oven.

Today’s modern living allows us to quickly throw away disposable products such as paper plates and cups if we’re only going to use them once; however, damaged dishes may still be used for short periods if they can not be replaced right away. 

Microwaving a plate with a crack or hole in the surface may cause it to ignite, but microwaving a dish that is otherwise free from damage is safe as long as you don’t heat it for longer than needed and use a reduced power setting on your microwave oven.

Frequently Asked Questions

  1. Do wooden spoons burn in the microwave? 

No, it will not. You can put the wood spoon in the microwave. 

  1. Can I use wood in my oven without it catching fire? 

Wood in the oven at around 100 degrees F can always catch fire. Wood will gradually char and ignite after a few hours at 450 to 500 degrees F. 

You can put wood in the oven, however, you should not put the small pieces or moistened wood slices of wood. 

  1. Can you put wood in a dishwasher? 

Never put wood into a dishwasher as this will accelerate any degradation caused by water damage. It is better to wash it by hand with warm water, soapy water and dry with a towel immediately. 

  1. Is it safe to eat food off of wooden plates or bowls? 

This answer depends on what is used to make the plate or bowl: dishes made from organic materials such as bamboo fibers or recycled paper pulp are safe if damaged slightly, but traditional disposable plates made out of thin layers of pressed wood pulp may catch fire if microwaved.

  1. How to care for wooden utensils?

Here’s how to care for your wooden utensils: 

  • First, make sure they are 100% dry before placing them in the dishwasher. 
  • Then, place 1-2 layers of paper towel between each utensil to protect them from heat; 
  • Never use detergent or soap on wooden utensils–using these products can cause the surface to become sticky and attract debris that is difficult to remove.
