Can You Microwave a Candle? The Safe and Easy Way to Melt Wax

Do you want a quick, safe and effective way to light your next candle? You’re in luck – microwaving a candle is the answer! Here we’ll discuss the safety, benefits and tips of microwaving your candles safely. So now, let’s explore the simple and satisfying solution to all your candle needs – can you microwave a candle?


Candles are an integral part of special events such as weddings and religious ceremonies, as well as everyday occurrences like lighting a room or creating ambience. Generally, to light a candle you can either use a match or lighter, which provide an open flame. However, many people might assume that using the more convenient method of microwave heating is also possible. In this article, we’ll discuss whether it’s safe to microwave a candle and explore the possible outcomes.

What Can Happen When You Microwave a Candle?

Microwaving a candle should be avoided due to the risk of fire or injury. When heated in a microwave, the wax of a candle can reach temperatures high enough to ignite. In addition to the fire hazard, individuals must remember that microwaves are designed to heat food items, not materials like candles. Moreover, microwaves lack proper ventilation for combustible materials like candles and this could further increase the risk of fire.

Moreover, when heated in a microwave environment there is an increased likelihood that fumes from any scented candles may cause damage to internal components within the appliance as well as trigger possible explosions. Given the multitude of variables that exist when heating anything inside of a microwave it is wise to avoid placing any item inside it which could cause extensive damage or potential harm to humans and pets alike.

Finally, candles should never be left unattended while microwaving and all instructions provided by candle manufacturers must be carefully followed in order for them to heat safely. Additionally, standard safety practices should always be employed when using any open flame including extinguishing any burning flames before leaving an area.

Are There Any Benefits to Microwaving a Candle?

Candles add atmosphere and warmth to any home or space. But what if you don’t have access to an open flame or a lighter? Can you really microwave a candle? Some candle experts believe microwaving a candle is safe and can offer some unique benefits.

For starters, microwaving a candle can help it burn more slowly, slowly releasing its scent into your home. It also helps create an even, consistent pool of wax on the surface of the candle that can make it so the wax won’t overflow the sides of the jar.

But be warned – microwaving candles does not come without risks. Make sure that there is no metal—including on decorations attached to your candle—near the open flame before lighting it. Even its small amount of metal on your candle will increase the risk for injury as hot wax spills onto nearby surfaces when lit. Additionally, depending on how powerful your microwave is, some candles may ignite suddenly in an unusually short amount of time, increasing the likelihood that you could be injured by burning hot wax and wick fragments when opening the door afterwards.

Therefore, always handle with caution when microwaving candles and remember to keep flammable materials away from open flames.

What Other Items Should Not Be Microwaved?

Ceramic tableware items and pottery such as clay pots and terra cotta containers cannot be safely heated in the microwave. These materials are often not labeled for use in microwave ovens as they tend to absorb heat unevenly which can cause cracking or other damage. Also, metal items or aluminum foil should never be placed inside the microwave. Metal reflects microwaves rather than absorbs them, greatly increasing the risk of an electric arcing or sparking fire inside your oven.

Similarly, if a metal object is placed too close to something that is being microwaved, it can cause an arcing spark – although this usually isn’t serious unless the metal object itself is large enough to cause more extensive damage. For instance, a fork that falls against a bowl that is being microwaved is not likely to cause any real harm but a large knife could cause sparks to fly which could ultimately start a fire inside the oven.

Other materials that should never be put in the microwave are:

  • Any type of plastic wrap or plastic bags;
  • Paper products such as paper plates, cups, towels and napkins;
  • Glass bowls with metallic trim;
  • Obviously candles – unless you want an exploding wax mess all over your kitchen!
  • Some common household items such as styrofoam packaging material and foam egg cartons should also never be put in the microwave due to their potential for melting or catching fire if heated for too long.

Safety Tips for Microwaving a Candle

Candles can be microwaved safely, but due to the presence of open flames and molten wax it is important to take safety precautions while doing so. Here are some tips to keep in mind before attempting to microwave a candle:

  1. Turn off any fans or air conditioners before microwaving candles as they may interfere with the burning process. Be sure that all other appliances such as TVs, computers, and light fixtures are also turned off.
  2. Ensure that the area is well-ventilated before you begin. Open a nearby window or door and leave it open while microwaving your candle in order to reduce fire hazards associated with flameless combustion (this pertains mostly to long lasting pillar candles).
  3. Place your candle in an appropriate container – this will help reduce heat loss from the hot wax or melted metal on the bottom of the container if there is any exposed unprotected wood or other combustible materials nearby (like curtains). It will also reduce fire hazard from splatter from uncapped wicks.
  4. Remember that unlike food items, candles usually do not have instructions for microwaveable usage on their label as microwaving them may cause an alteration in scent or coloration that alters consumer preferences for product use/aesthetic purposes). However, microwaving candles is generally safe if done with caution and care – just follow these steps!

Alternatives to Microwaving a Candle

Candle wax is typically not safe to warm in a microwave. In general, the temperature of the wax needs to reach over 200 degrees Fahrenheit (93.3 degrees Celsius) before it can be melted, and heating wax in a microwave can cause overheating, sparking and potential fires.

Instead of microwaving your candles, there are some alternatives you can consider that are much safer.

Alternative methods for melting wax include using a crockpot or double boiler. These methods allow you to maintain more consistent control over the temperature of the liquid wax and help reduce fire or spark risks. Additionally, these allow you to effectively melt larger quantities of wax in a shorter amount of time with some safety considerations such as placing on an insulated surface when hot and never leaving unattended while melting.

Other heat sources such as an oven or heated pot with water on the stove can work as well; however, these options don’t offer any temperature control so there is greater risk for sparking or fires due to an accidental increase in heat beyond what is safely required for melting candle wax. Utilizing lower settings or monitoring closely is key when using these options for melting candle wax safely.


In conclusion, it is not advised to microwave a candle as the intense heat could cause combustion, leading to fire and other disastrous consequences. Candles should be kept in an open and well-ventilated area while they are lit to ensure that the flame has plenty of oxygen and the temperature remains low enough for safety.

If you are looking to safely experience aromatherapy, a wax warmer or oil diffuser is recommended instead of a candle warmer.
