Can You Melt Candle Wax In The Microwave

Candles are a popular decorative item in households, often used for ambiance and relaxation. But what happens when the candle burns out? Many people wonder if they can melt the leftover wax in the microwave to reuse it. In this article, we will answer the question: Can you melt candle wax in the microwave?

Key takeaways:

  • Candle wax can be melted in the microwave, but it’s not always safe or effective.
  • Wax is flammable, and the temperature can be difficult to control in the microwave, which can lead to a lumpy and uneven mixture.
  • Safety precautions when melting candle wax in the microwave include using a microwave-safe container, a low power setting, stirring frequently, monitoring the wax closely, and letting the wax cool before handling.
  • Alternative methods of melting candle wax include using an oven, electric stovetop, or double boiler method, with the double boiler method being the safest and most effective.
  • Melted candle wax can be repurposed into new candles, wax melts, sealants, wax-dipped flowers, coatings for food, lubricants, and decorative art.

Can You Melt Candle Wax in the Microwave?

The short answer is yes, you can melt candle wax in the microwave. However, it is not always safe or effective to do so.

One of the biggest concerns with melting candle wax in the microwave is the potential for fire. Wax is flammable and can easily catch on fire if it gets too hot. Additionally, if the wax overheats, it can cause the container it’s in to melt or crack, leading to a messy and potentially dangerous situation.

Another issue with melting candle wax in the microwave is that it can be difficult to control the temperature. Microwaves heat unevenly, which means that some areas of the wax may become too hot while others remain solid. This can result in a lumpy, uneven mixture that is difficult to work with.

Tips for Safely Melting Candle Wax

If you do decide to melt candle wax in the microwave, there are several safety precautions you should take to minimize the risk of fire or other hazards.

  • Use a microwave-safe container: Not all containers are safe to use in the microwave. Make sure the container you choose is labeled as microwave-safe.
  • Use a low power setting: Set your microwave to a low power setting, such as 50%, and heat the wax in short intervals (15-30 seconds at a time) to avoid overheating.
  • Stir frequently: Stir the wax between each heating interval to ensure that it heats evenly and prevent hot spots.
  • Monitor the wax closely: Do not leave the microwave unattended while the wax is melting. Keep a close eye on it and stop heating immediately if you notice any smoke or other signs of overheating.
  • Let the wax cool before handling: Once the wax has melted, let it cool for a few minutes before handling it to avoid burns or other injuries.

Alternative Methods of Melting Candle Wax and Which One Is The Safest?

While it is possible to melt candle wax in the microwave, there are safer and more effective methods to consider.


Melting candle wax in the oven is a popular method because it allows for better temperature control. Preheat your oven to 200-250 degrees Fahrenheit, place the wax in a heat-safe container, and let it melt for about 10-15 minutes. Monitor the wax closely to prevent overheating.

Electric Stovetop

Using an electric stovetop is another effective way to melt candle wax. Fill a large pot with water and place a smaller pot or heat-safe container inside. Place the wax inside the smaller pot and heat the water to a simmer, stirring the wax occasionally until it melts.

Double Boiler

The double boiler method involves using two pots – one larger pot filled with water and a smaller pot placed inside.

The smaller pot is where the wax is placed, and it is heated by the steam generated by the boiling water in the larger pot. This method provides more consistent and even heating, and it minimizes the risk of overheating the wax.

Of these three methods, the double boiler method is the safest and most effective. It allows for more precise temperature control, and it minimizes the risk of overheating or burning the wax.

How to Use Your Melted Candle Wax

There are countless ways to use your melted candle wax, depending on your creativity and needs. Here are some popular ideas:

  1. Create New Candles: Pour the melted wax into a candle mold or a heat-resistant container with a wick to make a new candle. You can also add scents, colors, or other additives to customize the candle to your liking.
  2. Make Wax Melts: Pour the melted wax into small molds, such as silicone or ice cube trays, to create wax melts. Wax melts are a popular alternative to candles and can be used in wax warmers to scent a room.
  3. Use as a Sealant: Melted candle wax can be used as a sealant for envelopes, bottles, or other containers. Dip the end of a string into the wax and use it as a seal for your letters or packages.
  4. Wax Dipped Flowers: Melted candle wax can be used to preserve flowers or create a unique decorative effect. Dip flowers into the wax and let them dry to create a glossy, long-lasting effect.
  5. Coating for Food: In some cultures, melted candle wax is used as a coating for food, such as cheese or fruits. The wax helps to preserve the food and prevent it from spoiling.
  6. Lubricant: Melted candle wax can also be used as a lubricant for zippers, squeaky hinges, or other small mechanical items. Apply a small amount of wax to the affected area to reduce friction and make it run more smoothly.
  7. Decorative Art: Melted candle wax can be used as a medium for art projects, such as painting or mixed media. Apply melted wax to a canvas or other surface and let it dry to create a unique texture or design.


In conclusion, while it is possible to melt candle wax in the microwave, it is not always safe or effective to do so. If you choose to use this method, make sure to take the necessary safety precautions to minimize the risk of fire or other hazards.

Alternatively, using an oven, electrical stovetop, or double boiler method can provide better temperature control and minimize the risk of overheating the wax. Remember to always use caution and take safety seriously when working with hot wax.

With these tips and alternative methods, you can safely and effectively melt candle wax and repurpose it into new creations.
