There are many ways to melt down candles entirely and recycle the wax for new candles. The most popular methods for melting candle wax are the double boiler and the microwave method. The double boiler method involves placing a smaller pan, bowl, or pouring jug containing the wax inside a larger pan filled halfway with water. The wax is then heated over medium heat until it melts. The microwave method requires crumbling the wax into a microwave-safe container and heating it in short intervals until fully melted. Other methods include using an electric stove, placing the candle jar in the oven, or melting the wax in a saucepan over the stove. Regardless of the method chosen, it is important to follow safety precautions when melting wax.
Characteristics and Values Table for Melting Away Candles Entirely

What You'll Learn
Melting candles in the oven
While the oven is preheating, the candles will start to melt. The wax is ready when it has turned to liquid. Wear oven gloves and use a standard thermometer to check the wax's temperature. Be cautious and avoid letting the wax reach its flashpoint, the temperature at which it will ignite.
Once the wax is melted, carefully remove the tray from the oven and turn off the oven. You can now scoop out the wax and reuse it for your desired purpose.
An alternative method is to boil water and pour it into a pan, surrounding the candle jars. Leave the setup for about an hour, and the wax will melt. This method avoids the risk of the wax reaching its flashpoint.

Using a double boiler
A double boiler is a two-pot setup where a larger base pot contains simmering water, and a smaller pot fits inside it to melt wax gradually. This method is efficient and economical, and it makes the candle-making process easy and safe. Here is a step-by-step guide on how to melt wax using a double boiler:
Prepare the double boiler: Start by filling a large saucepan with water—about half full or 1-2 inches—and place it on the stove to heat.
Add the wax: Place your wax in a pouring pitcher, clean coffee can, smaller saucepan, glass bowl, or pouring jug. Ensure that the container is heat-safe. Then, put the smaller container in the larger saucepan.
Heat the wax: Heat the setup over medium-low heat until the wax is completely melted. Adjust the heat to a gentle simmer, never a rolling boil, to prevent overheating the wax. Carefully add more water to the larger saucepan as needed to prevent the water from evaporating.
Stir and monitor: Occasionally stir the wax to encourage melting and ensure even melting. Do not stir aggressively, as this can introduce air into the blend, impacting the final candle quality. Use a wooden or heat-safe spatula for stirring.
Monitor the temperature: Use a thermometer to monitor the temperature of the wax. Different waxes melt at different temperatures, so knowing the correct temperature for your specific wax is essential. For example, soy wax melts at around 120°F to 140°F, beeswax at 145°F to 175°F, and coconut wax at 100°F to 120°F. Most wax should be heated to around 185°F before adding fragrance, but always check your wax supplier's instructions.
Add colour and fragrance: Once the wax has melted, you can add colour and fragrance if desired. Typically, you should wait until the wax cools down to around 70°C before adding colour and fragrance. Stir the blend for about two minutes to ensure that the colour and fragrance are well dispersed.
Pour the wax: After adding colour and fragrance, your wax is now ready to be poured into your chosen container. Pour the wax at a steady rate, not too fast and not too slow, to avoid introducing too much air into the blend.
It is important to stay near the double boiler at all times and ensure proper ventilation during the process to avoid inhaling any fumes. Additionally, any pan used for melting wax should not be used for food preparation afterward.

Melting in the microwave
Melting candles in the microwave is a quick and easy method, but it does come with some risks. It is important to be vigilant and careful throughout the process.
Firstly, you need to find a microwave-safe container. Most containers will have a label on the back that will tell you if they are safe to use in a microwave. If you are unsure, look for a symbol of a dish with wavy lines above it.
Next, break the candle into small pieces and put them into the container. The smaller the pieces, the faster the melting process. Place the container in the microwave and heat for one-minute intervals, keeping a close eye on the wax. If the wax starts to smoke or you think it is getting too hot, take it out immediately.
Once the wax has melted, carefully remove the container from the microwave. Be sure not to place the hot container on a cold surface, as this could cause it to crack. You can now use the melted wax to create new candles or for other craft projects.
It is important to note that some types of wax, such as paraffin wax, are not suitable for melting in the microwave. Always check the original packaging of the candle to find the flashpoint of the wax, which is the temperature at which it will catch fire. Use a cooking thermometer to ensure the wax does not exceed this temperature.
While melting candles in the microwave is a convenient option, it may not always yield the desired results. The traditional method of melting wax over warm water is generally recommended as it provides more control over the temperature and reduces the risk of fire.

Preparing candle vessels
The size of the vessel will determine the cost and aesthetic of your candle. Larger jars will require more wax, fragrance oil, dye, and possibly larger wicks, increasing the overall expense. Choose a size that balances your desired cost and visual impact. If you're creating a smaller candle, consider using a vintage teacup, a crystal cup, or a coffee mug as your vessel. These options are not only heat-resistant but also add a unique and elegant touch to your candle.
For a more rustic or country look, upcycling old items from around the house or thrift stores is environmentally responsible and cost-effective. Cookie tins, for example, make excellent candle vessels due to their sturdy and heat-resistant construction. Their tight-fitting lids also make them perfect for gifting. Empty glass bottles can also be transformed into sustainable and fashionable candle vessels.
If you're creating multiple candles or experimenting with different colours, divide your wax into multiple containers and add different amounts of dye to each. This will allow you to create a stunning gradient effect when poured into your prepared candle vessels.

Adding scents
Adding a scent to your candles is a great way to customise them and make them excellent gifts. You can add fragrance oils, essential oils, or even perfume samples to your melted wax.
Firstly, it is important to consider the underlying smell of the recycled wax. For example, a pumpkin pie candle and an apple pie candle will probably combine to smell like baked goods. However, a pumpkin pie candle and a floral candle will probably smell confusing and over-perfumed, as these scent profiles are very different and are not usually paired together.
You can also add citronella oil to make a natural bug repellent. Add five to ten drops of citronella oil to the melted wax and stir. You can also add other scented oils, but be sure to keep in mind the original scent of the wax.
If you are using the remains of several scented candles, make sure the combination of aromas will complement each other. You could also add pressed flowers to the wax.
When adding fragrance oil, it is recommended to use 6-10% of fragrance oil, which should be weighed in grams on your scales. Give the wax a good stir, ensuring the colour and fragrance are blended with the wax.
