What You'll Learn
Use a double boiler
Using a double boiler is an efficient, economical, and beginner-friendly way to melt old candles. It involves melting wax inside a container that's sitting in a pot of boiling water. Here's a step-by-step guide on how to do it:
Prepare the double boiler
Fill a large saucepan or pot about halfway with water and place it on the stove to heat. The water should be heated to a gentle simmer, never a rolling boil, to ensure even heating of the wax. This will serve as the bottom part of your double boiler setup.
Add the wax
Place your old candle wax in a smaller, heat-safe container, such as a pouring pitcher, clean coffee can, smaller saucepan, glass bowl, or pouring jug. Ensure that the container can withstand the temperature of boiling water, which is typically around 185°F - 212°F (85°C - 100°C). This container will sit inside the larger pot without touching the bottom, creating the top part of your double boiler.
Stir and monitor
As the wax begins to melt, use a wooden or heat-safe spatula to stir the wax occasionally. Stirring helps ensure even melting and prevents introducing too much air into the blend, which can impact the final candle quality. It's important to monitor the temperature of the wax with a thermometer to avoid overheating. The ideal melting temperature varies depending on the type of wax; soy wax, for example, melts at a lower temperature (120°F to 140°F) than beeswax (145°F to 175°F).
Add colour and fragrance (optional)
Once your wax has completely melted, you can add colour and fragrance if desired. There are no rules when it comes to colouring your candles, but keep in mind that different waxes take on colour differently. Soy wax, for instance, will appear more muted or pastel-like compared to paraffin, which closely matches the colour you add. After adding colour and fragrance, stir well to ensure the oil is evenly dispersed in the blend.
Pour into a mould
Finally, carefully pour your melted wax blend into a mould or container at a steady rate. If you're making multiple candles, pour about 75% of the wax into each mould and then top them off in the same order.

Prepare your mould
Preparing your mould is an important step in the candle-making process. You can use a variety of containers as moulds, such as a jar, a teacup, a ramekin, a short mason jar, or even a silicone mould. It is important to avoid using plastic containers as they can melt. Place a paper towel or cardboard underneath your mould to catch any wax spills.
If you are using a reusable wick, ensure that it is suitable for the size and type of candle you are making. Place the wick in the centre of your chosen mould and secure it in place by laying a pencil, toothpick, or popsicle stick across the top of the mould, with the wick folded over it.
For new candles, you can add colour dyes or fragrance oils to the melted wax before pouring it into the mould. This allows you to personalise your candles and create unique scents and colours. You can even mix leftover coloured wax to create new colours.
Once your mould is prepared, you can carefully pour the melted wax into it. Fill the mould mostly to the top, leaving some space to prevent overflow. It is important to let the wax cool completely before removing it from the mould to ensure it holds its shape. The cooling time may vary depending on the size and shape of your mould, typically taking anywhere from 30 minutes to a few hours.

Melt wax slowly
Melting old candles is a great way to create new candles for free. It's a simple process, but it's important to take safety precautions and melt the wax slowly to avoid overheating or fire hazards. Here are some detailed instructions to guide you through the process:
Firstly, gather the remnants of your old candles. These can be half-used candles, broken candles, or small stubs. Remove as much dirt and old wicks as possible. You can use a knife or spoon to scrape out the leftover wax. If you're having trouble, try placing the candle in the freezer first, as this can make it easier to remove the wax.
Now, prepare your equipment. You will need a double boiler, which is a heat-resistant bowl or pot that you place over a pan of water. Fill the pan with water and place it on the stove. You only need a few inches of water, enough to cover the bottom of the pan. Turn on the heat and bring the water to a gentle simmer. Do not let the water reach a rolling boil, as this can cause your container to bounce around.
Place the old candle remnants in the heat-resistant bowl or pot and ensure the heat is low. The steam from the simmering water will slowly melt the wax. This process may take some time, so be patient. Stir the wax occasionally to ensure it melts evenly. If your wax is melting too quickly or unevenly, try placing a heat-resistant object, like a plate or lid, on top of the bowl to regulate the temperature.
While you wait for the wax to melt, prepare your new candle container. You can use an old candle container, a crystal votive holder, a teacup, a mini vase, a ramekin, or even a short mason jar. Choose something that fits your style and decor. Place a wick in the centre of your chosen container. You can use a new wick or reuse an old one if it's still in good condition. Secure the wick by placing a pencil, toothpick, or popsicle stick across the top of the container and folding the wick over it.
Once the wax is completely melted, you can carefully pour it into your prepared candle container. Ensure the wick remains upright and centred. Allow the wax to cool and harden completely. This may take anywhere from 30 minutes to a few hours, depending on the size of your new candle. Finally, trim the wick to about half a centimetre above the candle's surface, and your new candle is ready to burn!

Add colour or fragrance
Once you have melted your wax, you can add colour and fragrance. If you are using scented wax from multiple sources, consider how the fragrances will blend. If you are using unscented wax, you can add essential oils. For example, wax infused with citrus oils may not mix well with wax infused with lavender oil, as they tend to produce opposing moods when released into the air.
Similarly, if you are combining different-coloured candles, consider how the tones will blend after melting. Colours that are close to each other tend to work well, while those that are opposite may not create an attractive finish. A general guideline for adding fragrance is about 1 ounce of fragrance per pound of wax, but you can adjust this based on your preference.
If you want coloured candles, add your colourant and stir until the colour is evenly distributed. Let the wax cool slightly before pouring. A suitable pouring temperature is typically around 130-140°F (55-60°C), but this can vary depending on the type of wax. You can also add dried spices and herbs to your candles, as well as cedar shavings.

Reuse wicks
Reusing candle wicks is an easy way to save money and create new candles. Before reusing a candle wick, ensure that you have all the supplies you need, such as a double boiler or saucepan for melting the wax, a heat source, and stirring tools. It is also important to always exercise caution and safety measures when handling hot wax.
If your wick is buried under the surface of the wax, use a spoon or a butter knife to carefully scrape away the wax until the wick is exposed. You can also use a lighter or a hairdryer to melt the wax, but be sure to collect the excess wax in a separate heat-safe container. Avoid digging a deep hole to expose the wick, as this will cause the candle to burn down the centre, eventually drowning the wick.
If your wick is too short, you can extend it by dipping it in wax, which will help it burn more slowly and evenly. You can also use a makeshift paper wick by rolling up a scrap of thicker paper, like notebook or copy paper, into a tight roll. Avoid using coloured paper or magazine pages, as the ink fumes can be toxic. If you're looking for an even slower burn, opt for a wooden wick.
To replace a candle wick, first, remove the old wick using tweezers or pliers. Squeeze the metal piece at the bottom of the wick with needle-nose pliers to open it, then pull out the old wick and discard it. Thread the new wick through the same hole and pinch it closed with pliers. Alternatively, use hot glue to attach the new wick to the bottom of your candle container.
