How to remove wax from old candles
Melting down old candles to create new ones is a fun and cost-effective project. Here is a step-by-step guide on how to remove wax from old candles:
Preparing the Wax
Firstly, you need to remove the leftover wax from your old candles. You can use a knife or spoon to do this, and some people find it easier to place the candle in the freezer first. Break the wax into smaller pieces, which will be easier to melt.
Melting the Wax
There are several methods for melting the wax. One is to use a double boiler, or bain-marie, method. Place the wax pieces in a can, and put this in a saucepan of water at a gentle boil. The water should not be boiling vigorously, as this could cause the can to bounce around. You can place a weight on top of the can, such as a plate or lid, to keep it stable.
Another method is to use an oven. Preheat your oven to the melting point of your wax, which should be detailed on the candle packaging. Place the wax pieces in a baking tray and put them in the oven for around 10 minutes, or until the wax has completely melted. Keep a close eye on the wax while it is in the oven.
You can also melt the wax in a microwave. Place the wax pieces in a bowl and heat on high for 4 minutes. Leave the bowl uncovered so that the heat can work more effectively. Stir the wax as it cools, and check the temperature with a thermometer. Wax has a flashpoint, or ignition temperature, which you should be aware of.
Preparing the Container
While your wax is melting, prepare your new candle container. You can reuse old candle jars, as long as you clean them with boiling water first. You can also use tins from a candle-making kit, or other containers such as teacups, miniature vases, or short mason jars. Place the wick in the centre of your chosen container, sticking it to the bottom with the adhesive provided, or with sticky wick tabs. Brace the wick with a pencil or popsicle stick to keep it upright.
Pouring the Wax
Once your wax has completely melted, carefully remove the container from the heat source, using tongs if necessary. Slowly pour the wax into your prepared container, leaving at least half an inch of space at the top. Leave the candles to cure in a warm spot, so that they cool down slowly and don't crack or split. Leave them undisturbed for 24 to 48 hours.
Now you have a new candle, ready to burn!

Preparing your new candle container
Choose a Suitable Container
First, select a container that suits your preferences and the purpose of your new candle. You can reuse old candle jars, opt for cute jars or vessels, or even use fresh tins from a candle-making kit. Other options include crystal votive holders, teacups, miniature vases, ramekins, crystal cups, or short mason jars. Be creative and choose a container that aligns with your home aesthetic or makes for an excellent gift.
Clean the Container
If you're reusing an old candle jar, ensure you clean it thoroughly before pouring in the new wax. Boil some water and pour it into the jar, letting it sit for about an hour. This will help soften and remove any remaining wax residue. You can then wipe the jar clean with a cloth or paper towel.
Prepare the Wick
Place the wick in the centre of your chosen container. Most wicks come with double-sided stickers. Peel off one side and attach the sticker to the centre of the container. Then, peel off the other side and stick the metal base of the wick on top. Ensure the wick is secure and stands upright. If your wick is too short or unstable, brace it with a pencil, toothpick, or popsicle stick laid across the top of the container.
Prepare for Pouring
Before pouring the melted wax, ensure your container is ready. Place your container on a stable, heat-resistant surface, such as a wooden cutting board or an oven mitt, to protect your countertops from heat damage. If your container doesn't have a spout, consider transferring the melted wax to a heatproof, pre-warmed measuring cup to make pouring easier.
Additional Tips
When melting wax in the oven, always use low heat. You don't want the wax to boil and create a mess. Place your container on a metal sheet in the oven to catch any potential spills. Additionally, ensure your wax is at least 30-50°F (1-10°C) below its flash point, which is the temperature at which the wax will ignite. Always prioritise safety when working with hot wax.

Melting the wax
Melting wax from old candles is an easy and cost-effective way to create new candles. The process is simple and can be done using a variety of methods, such as a stovetop, oven, or microwave. Here is a step-by-step guide to melting wax from old candles:
Preparing the Wax
First, you need to remove the leftover wax from your old candles. This can be done by placing the candle in the freezer for a few hours and then gently prying the wax out with a knife, spoon, or chopstick. If your candle has completely melted into its container, you can place the jar in a shallow pan of boiling water for about an hour to soften the wax and make it easier to remove. Once you have removed the wax, break it into smaller pieces with your hands or a knife.
Choosing a Melting Method
There are several ways to melt the wax. You can use a stovetop, oven, or microwave. Each method has its advantages and considerations:
- Stovetop: This method involves creating a double boiler by placing a heat-safe container with the wax into a saucepan of barely boiling water. This is a safe and effective way to melt the wax gently.
- Oven: Preheat your oven to the melting point of your wax, which should be detailed on the candle packaging. Place the wax in a heat-safe container and put it in the oven once heated. Keep an eye on the wax as it melts, as the oven can be more dangerous than other methods.
- Microwave: Place the wax in a microwave-safe bowl and heat it for about 4 minutes. The microwave will not completely melt the wax, but it will soften it, making it easier to melt further with a stove or oven.
Once you have chosen your melting method, follow these general steps:
- Place the wax in the preheated oven or heated container on the stovetop or in the microwave.
- Heat the wax until it is completely melted. This may take a few minutes to around 25 minutes, depending on the method and the amount of wax.
- Keep the heat low to avoid boiling the wax, which can make a mess.
- Use oven gloves or tongs to handle hot containers and always be cautious of hot wax.
Preparing the New Candle Container
While your wax is melting, prepare your new candle container. Clean old candle jars with boiling water or use fresh tins from a candle-making kit. Place the wick in the centre of the container, using double-sided stickers or sticky wick tabs to secure it. You can use a pencil or popsicle stick to keep the wick upright as you pour the wax.
Now that your wax is melted and your new container is prepared, you are ready to pour the wax and create your new candle!

Pouring the wax into the new container
When melting down old candles to make a new one, there are several methods you can use to pour the wax into a new container. Here is a step-by-step guide:
First, prepare your new container by placing a wick in the centre. You can use a pencil, toothpick, or popsicle stick to hold the wick in place. There are also sticky wick tabs available, which can be used to attach the wick to the bottom of the container. Ensure the wick is held upright and secure before pouring in the wax.
Next, you will need to melt your wax. You can do this in the oven, on a stovetop, or in the microwave. If using the oven, preheat it to the melting point of your wax, which should be detailed on the candle's packaging. Place the wax in a baking tray and heat until it has completely liquefied. Alternatively, you can use a double boiler method on the stovetop by placing a can containing the wax bits into a saucepan of barely boiling water. If using the microwave, crumble the wax into a bowl and heat in short intervals, stirring between each interval.
Once your wax is melted, it's time to pour it into your prepared container. If the vessel doesn't have a spout, consider transferring the wax to a heatproof measuring cup to make pouring easier. Go slowly and carefully to avoid spilling. Leave at least half an inch of space at the top of the container to allow for expansion.
Finally, allow your new candle to cool and harden. Place it in a warm spot and let it sit undisturbed for 24 to 48 hours. This slow cooling process will prevent cracking and ensure your candle lasts longer.

Allowing the new candle to cure
To start the curing process, remove your melted wax from the heat source. If using a double boiler, carefully lift the pot out of the water using tongs or oven gloves. If you are melting the wax directly in the oven, turn off the heat and remove the wax once it has cooled slightly. Be careful not to spill the hot wax as you transfer it.
Next, slowly pour the melted wax into your prepared candle container. Leave at least half an inch of space at the top to allow for expansion and to avoid overflow as the wax cools. Go slow and be patient during this step to ensure a smooth and even pour.
After pouring, leave your candles undisturbed for 24 to 48 hours. They may appear hardened much sooner, but it is best to wait until they are fully set to ensure the best quality and longevity. During this time, the wax will cool and harden, forming a smooth and even surface.
The curing process is crucial as it allows the candle to set properly, which will affect its burning characteristics. A candle that has been allowed to cure slowly and completely will burn more evenly and last longer. This step may require patience, but it is worth it to ensure the best results for your homemade candle.
