Make new candles
Making new candles from old ones is a great way to recycle and be creative. There are several ways to go about it, depending on the type of candle you have and the equipment you have at home.
One method is to melt the wax of your old candles and pour it into a new mould with a new wick. You can buy candle-making supplies, like wicks and moulds, from craft stores. To melt the wax, you can use a double-boiler technique, which involves placing the old candle in a small pot and then placing that pot inside a larger pot filled with simmering water. Bring the water to a simmer, and the wax will melt without the jar getting too hot. You can also melt the wax in an oven set to a low temperature, but be sure to remove any labels or stickers first.
Another method is to freeze the candle and then use a butter knife to pop the wax out of the container. This method is good if you want to reuse the container for your new candle. Once you have removed the wax, you can melt it down and pour it into your chosen mould with a new wick.
If you have a candle warmer lamp, you can use this to melt the wax without using water or an oven. Simply place the old candle in the warmer, and once the wax has melted, pour it into your chosen mould.
When making new candles, it's important to ensure safety. Never put a jarred candle in the microwave, as the metal disc that attaches the wick to the holder can be dangerous. Always be careful when handling hot wax, and make sure to use heat-safe equipment.

Make wax melts
If you're looking to reuse your spent candles, making wax melts is a great option. Wax melts are scented pieces of wax that can be melted in a candle or tart warmer to release fragrance. Here's a step-by-step guide to making your own wax melts from spent candles:
Step 1: Remove Wax from Spent Candles
First, you'll need to remove the leftover wax from your spent candles. There are several ways to do this:
- Freezer Method: Place the spent candles in the freezer for a few hours until the wax is frozen. Then, use a butter knife to pop the wax out of the container.
- Double Boiler Method: Fill a saucepan with water and place the old candles in a glass jar into the saucepan. Slowly bring the water to a boil, melting the wax.
- Oven Method: Preheat your oven to its lowest setting. Remove any labels or stickers from the candle jar and place it in the oven. Once the wax is melted, scoop it out.
Step 2: Melt the Wax
Once you have removed the wax from your spent candles, it's time to melt it down. You can use a double boiler method again or place the wax in a heat-safe container and melt it in the microwave in short intervals. Be careful not to overheat the wax, as it can catch fire.
Step 3: Add Fragrance and Colour (Optional)
If you want to enhance the fragrance or add colour to your wax melts, now is the time to do it. You can add a few drops of essential oil or fragrance oil to the melted wax. To add colour, use special candle dye or a small amount of crayon shavings. Stir well to combine.
Step 4: Pour Wax into Moulds
Pour the melted wax into small moulds, such as an ice cube tray or silicone moulds. You can also use empty tealight cups if you plan to use them as tealights. If using moulds, place a wick in the centre of each mould, holding it in place with a toothpick.
Step 5: Let the Wax Cool and Solidify
Allow the wax to cool and solidify completely before removing it from the moulds. This may take a few hours, depending on the size and depth of your moulds.
Step 6: Package and Store
Once your wax melts are fully solidified, you can package them in airtight containers or bags. Store them in a cool, dry place until you're ready to use them.
Making wax melts from spent candles is a fun and creative way to reduce waste and enjoy your favourite fragrances for longer. Experiment with different colours, fragrances, and mould shapes to create unique and personalised wax melts.

Make fragrance pouches
If you want to make fragrance pouches from your spent candles, you will first need to remove the wax from the candle jar. There are several ways to do this:
- Place the candle jar in a bowl set over a pot of barely simmering water. This will ensure the wax melts without the jar getting dangerously hot.
- Place the candle in a separate pot and slowly pour boiling water around it, making sure the water doesn't go into the candle jar.
- Place the candle jar in the freezer. This allows the wax to shrink and easily pop out when the candle holder is removed from the freezer.
- Place the candle in an oven preheated to its lowest setting. Once the wax is melted, scoop it out.
Once you have removed the wax from the jar, you can start making your fragrance pouches. Here are the steps:
- Melt the leftover wax and allow it to cool to room temperature.
- Place the melted wax in the freezer for a few hours until it solidifies.
- Cut the solidified wax into small pieces.
- Place the wax pieces in a small linen pouch.
- If you want to make the scent stronger, you can mix in your own fragrance oils or herbs.
Your fragrance pouches are now ready to be used! You can place them in small spaces like closets, clothing drawers, or even inside your car to add a pleasant scent.

Make fire starters
Making fire starters is a great way to reuse old candle wax. This project was dreamed up by Ashley Poskin and involves using wax flakes, cedar shavings, and dried flowers and herbs. It's a simple way to create a cosy glow in your fireplace without the need for an armload of kindling.
Firstly, gather the herbs and spices you want to use and break them into smaller pieces that will fit into the cups of a carton. Set the egg carton on a sheet pan lined with wax paper. Be sure to pack the bottom of each cup with cedar shavings, but don't overfill it. You want to leave enough space so that the melted wax won't flow out through the bottom.
Next, melt your old candle wax. You can do this by placing the jar in a bowl set over a pot of barely simmering water. This will ensure the wax melts without the jar getting dangerously hot. Alternatively, place the candle in a separate pot and slowly pour boiling water around it, making sure the water doesn't go into the candle jar. You can also melt the wax in the oven by placing the jar inside, preheated to its lowest setting, but remember to remove any labels or stickers first.
Once the wax is melted, carefully pour it into the egg carton cups. Allow the wax to harden, then remove the fire starters from the carton. Now you're ready to light up your fireplace!

Once the wax has been removed, the container can be reused in a variety of ways. Some people choose to use the containers as drinking glasses or plant pots. Others fill the containers with new wax and wicks to make their own candles. Candle containers can also be used for storage, such as holding small items like paper clips or pins. They can also be used as decorative pieces, especially if they are made of decorative glass or have interesting shapes.
If you want to make your own candles using the old candle containers, you will need to purchase candle-making supplies, such as wicks and wax. You can find these supplies at most craft stores. When making your own candles, it is important to follow safety precautions, such as not using a knife or sharp object to remove wax from the container, as this can scratch or weaken the glass.
