Melting old candles is a great way to create new ones for free. The process is simple: place wax scraps into a pot or bowl (a double boiler) and fill the bottom half with water. Set it on the stove and let the wax melt, stirring occasionally. Once melted, remove old wicks and pour the wax into a new container with a wick. Leave it to cool and you have a new candle! This method is cost-effective, easy, and customizable. However, it's important to note that wax does not boil and direct heat sources, like stove burners, should be avoided. Always use the double-boiler method to prevent the wax from catching fire.

What You'll Learn
Prepare the wax by removing it from its container
To prepare the wax, start by freezing the candle jar. This will cause the wax to shrink, making it easier to dislodge. Place the jar open-side-up in a shallow pan or baking sheet. You can place it on your stovetop, a wooden cutting board, or an oven mitt to protect your countertops. Boil a couple of cups of water and pour some into the pan so it surrounds the jar. Let the water get as high as possible without risking a spill. Fill the jar with water, leaving a bit of space below the rim. Leave this setup for about an hour.
After an hour, gently pop the wax out of the jar. If the wax is too hard to remove, try using a knife or spoon to help dislodge it. You can also try placing the jar in the freezer for several hours before gently prying at the wax with a gentle implement, like a chopstick. Once the wax is removed, clean any remaining residue with a cloth or scrub.
Now that the wax is removed from its container, you can begin the process of melting it down. It is important to note that different types of wax have different melting points, ranging from 100 to 145 degrees Fahrenheit. Soy wax, for example, will melt at a different speed than wax candles. Always use a "double boiler" method to melt the wax. Place the wax scraps into a pot or bowl that will serve as the top half of the double boiler. Fill a saucepan or the bottom of your double boiler halfway with water. Set the wax container inside the saucepan, ensuring that the bowl does not touch the water or the bottom of the pan. Set the heat to medium and allow the wax to melt, stirring occasionally with a wooden implement.
Remember to never heat wax over a direct heat source, as it can ignite without warning. Always use a thermometer to monitor the temperature of the wax and ensure it stays below its flash point. If the wax gets too hot, remove the bowl from the heat and allow it to cool before proceeding.

Use the double-boiler method to melt the wax
To melt your old candles using the double-boiler method, start by placing a saucepan on the stove and filling it with water. The exact amount of water is not important, but it should be about halfway full. Next, take a pot or bowl and fill it with your wax scraps. This will be the top half of your double boiler. Ensure that the bowl is made of glass or metal and is large enough to nest inside the saucepan without touching the water or the bottom of the pan. Place the container of wax scraps inside the saucepan.
Turn on the stove and set the heat to medium. Allow the wax to melt, stirring occasionally with a wooden spoon or implement to ensure even heating. The melting process should take anywhere from five to ten minutes, depending on the amount and type of wax. Different types of wax have different melting points, ranging from 100 to 145 degrees Fahrenheit, so some waxes may take longer to melt than others.
As the wax melts, use a thermometer to frequently monitor its temperature. Wax does not boil; instead, it will ignite if it gets too hot. The flash point is the temperature at which the wax will ignite, and your wax should always be at least 30 to 50 degrees Fahrenheit below this point. If the wax gets close to its flash point, use oven gloves to remove the bowl from the saucepan. Allow the wax to cool before placing it back into the pan if you need to reheat it.
Once the wax has melted, remove the old wicks with tongs and discard them. You can now use the melted wax for your desired project, such as making new candles or creating homemade wax melts.

Never heat wax directly over a stove burner
Melting old candles to create new ones is a fun and cost-effective project. However, it is important to take certain precautions to ensure safety. One key thing to remember is to never heat wax directly on a stove burner. Here's why:
Wax has a low melting point, typically ranging from 100 to 200 degrees Fahrenheit, with some types of wax melting at even lower temperatures. For example, soy wax melts around 120 degrees Fahrenheit. This means that it is very easy to unintentionally heat the wax to a much higher temperature than necessary when using a direct heat source like a stove burner.
Heating wax to temperatures far beyond its melting point can lead to several issues. Firstly, it increases the risk of fire. Wax has a flash point, the temperature at which it can ignite, which is typically far higher than its melting point. For example, while the melting point of wax is below 200 degrees Fahrenheit, its flash point is closer to 400 degrees Fahrenheit. Placing wax directly on a stove burner makes it challenging to control the temperature and increases the risk of reaching the flash point.
Additionally, overheating wax can negatively impact its quality and performance. When wax is heated excessively, it can break down or become compromised, affecting its ability to harden properly and perform as expected when reused in a new candle.
To safely melt wax, it is recommended to use a double boiler method. This involves placing a pot or bowl containing the wax scraps inside a larger saucepan filled with simmering water. This setup ensures that the wax is heated indirectly and allows for better temperature control. By using this method, you can melt the wax effectively without risking overheating or causing a fire.
In summary, never heat wax directly on a stove burner to avoid the dangers of overheating. Instead, opt for the safer double boiler method to melt your wax gently and effectively. This way, you can enjoy creating new candles from old wax without compromising safety or the quality of your final product.

Stir wax occasionally to ensure even heating
When melting old candles down by boiling, it is important to stir the wax occasionally to ensure even heating. This is because different types of wax have different melting points, ranging from 100 to 145 degrees Fahrenheit. By stirring the wax, you can help to distribute the heat more evenly and prevent hotspots or uneven melting.
To do this effectively, use a wooden spoon or another heat-safe implement to gently stir the wax as it melts. It is important to avoid using metal utensils as they can get very hot and potentially cause burns. Stirring also helps to speed up the melting process by breaking up any large chunks of wax that may be taking longer to melt.
Additionally, if you are melting down multiple candles with different types of wax, stirring can help to ensure that the waxes combine properly. This is especially important if you are planning to create new candles with the melted wax, as unevenly mixed wax can result in a poor-looking and poorly burning candle.
However, it is important to be cautious when stirring hot wax. Make sure to wear oven gloves or use tongs to protect your hands from the heat. Always stir slowly and carefully to avoid splashing or spilling the hot wax, which could cause burns or create a fire hazard.
Remember, melting wax can be dangerous if not done properly. Always take the necessary precautions, such as using a double boiler, monitoring the temperature, and never leaving the melting wax unattended. By stirring occasionally and following these safety guidelines, you can ensure that your wax melts evenly and safely.

Pour the melted wax into a new container
When your wax is melted and free of impurities, it's time to pour it into a new container. But first, you need to prepare your container. You can reuse old candle jars, but make sure to clean them with boiling water first. Alternatively, you can use fresh tins from a candle-making kit, or get creative with containers from antique stores or thrift stores, such as crystal votive holders, teacups, miniature vases, crystal cups, or short mason jars. Just make sure that your container can hold up to melted wax; thick canning jars or punch bowls made of thick glass are ideal.
Next, place your wick in the centre of your chosen container. Most wicks come with double-sided stickers. Peel off one side and place the sticker in the centre of your container. Peel off the other side and stick the metal base of the wick on top. If your wick doesn't stand up straight, you may need to brace it with something like a pencil, toothpick, or popsicle stick.
Now you're ready to pour your wax. If you're using the double-boiler method, remove the melted wax from the heat. If the vessel doesn't have a spout, transfer the wax to a glass measuring cup to make pouring easier. Slowly pour the wax into your prepared container, leaving at least half an inch of space at the top.
The time it takes for your new candle to cool and set will depend on the shape of your container and the amount of wax. It can take anywhere from 30 minutes to a few hours. Ideally, place your candle in a relatively warm spot so it cools down very slowly, which will prevent it from splitting.
