Candles are great for creating a cosy atmosphere, but they can be expensive and it's frustrating when there's leftover wax that you can't burn. Luckily, there are several ways to melt candles out of their containers so that you can reuse the wax or repurpose the jar. This includes using the oven method, the stovetop method, and the freezer method.
How to melt candles out of containers
| Characteristics | Values |
|---|---|
| Method 1 | Place the candle in a small pot, then place the small pot inside a larger pot filled with water. Bring the water to a simmer. |
| Method 2 | Preheat the oven to a low temperature (between 150°F and 170°F or 65°C to 75°C). Place the jar on a baking tray and put it in the oven for 10 to 15 minutes. |
| Method 3 | Place the jar in the freezer. This will cause the wax to shrink and pop out of the container. |
| Notes | Different types of wax have different melting points, so some waxes may take longer to melt. |

What You'll Learn

Using the oven method
The oven method is a safe and effective way to melt the wax in a glass candle jar without overheating the glass. Here is a step-by-step guide on how to do it:
Prepare the oven and the jar:
First, preheat your oven to a low temperature, somewhere between 150°F and 170°F (65°C to 75°C). Higher temperatures may cause the glass to crack. Place your glass jar on a baking tray lined with aluminium foil to catch any wax that might overflow.
Melt the wax:
Place the tray with the jar on it in the oven and let the wax melt. This should take around 10 to 15 minutes. Keep a close eye on it to avoid overheating.
Remove the jar and reuse the wax:
Once the wax has melted, carefully remove the jar from the oven using oven mitts as it will be very hot. You can then pour the melted wax into a mould or another container for reuse. If you are reusing the wax to make a new candle, you can add a few drops of essential oil and place pressed flowers in the wax before it hardens.
Additional tips:
If you are melting multiple candles with different scents, consider whether the scents will complement each other. If you are combining different colours of wax, they may mix to form a muddy brown.

Using a hot water bath
Step 1: Set up the hot water bath
Fill a large pot or pan with water and place it on your stove. The amount of water is not too important, but it should be enough to cover the height of the container with the candle. Place a smaller heat-proof container, such as a small pot or glass bowl, inside the large pot. Make sure that the small container does not touch the bottom of the pan.
Step 2: Prepare the candle container
Place the candle container open-side up in the smaller container. Ensure that the water level does not exceed the height of the candle container. If your candle has melted into a fragile candlestick, you can put it in the freezer for several hours before gently prying at the wax with a gentle implement like a chopstick.
Step 3: Heat the water
Turn on the stove and bring the water to a simmer. Different types of wax have different melting points, ranging from 100 to 145 degrees Fahrenheit, so adjust the heat accordingly.
Step 4: Melt the wax
Allow the steam and residual heat from the water to gently melt the wax inside the candle container. This process might take a bit longer than oven or microwave methods, but it is safer for containers that may not handle direct heat well.
Step 5: Remove the container and repurpose the wax
Once the wax has fully melted, carefully remove the container from the hot water bath. You can now pour out the wax and repurpose it for new candles, wax melts, or even homemade fire starters. Don't forget to remove old wicks and metal wick holders with tongs before reusing the wax.

Straining the wax
Preparing the Wax
Before you begin straining, it's important to sort your wax scraps. If you're only working with unscented candles of the same colour, you can skip this step. However, if you're combining the remnants of multiple scented or coloured candles, consider whether the scents and colours will complement each other when melted together. Remember that wax and soy candles generally play well together when melted down, but they will melt at different speeds and require stirring.
Melting the Wax
There are several methods you can use to melt the wax safely. One popular method is the oven method, which involves placing your glass jar on a baking tray lined with aluminium foil to catch any wax overflow. Set your oven to a low temperature, ideally between 150°F and 170°F (65°C to 75°C), as higher temperatures may cause the glass to crack. Place the tray in the oven and let the wax melt for 10 to 15 minutes, keeping a close eye on it to avoid overheating.
Alternatively, you can use a double boiler method. Fill a saucepan or the bottom half of a double boiler halfway with water and place it on the stove. Put your wax scraps into a pot or bowl that will serve as the top half of the double boiler, ensuring it doesn't 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 spoon to ensure even heating.
Straining and Reusing the Wax
Once your wax is fully melted, it's time to strain it. Use a fine-mesh strainer or cheesecloth to strain the melted wax and remove any impurities, such as metal wick pieces. Your wax may still look a bit murky after straining, especially if you've mixed colours. After straining, you can pour the wax into a mould or another container to create a new candle. You can also add a new wick and some fragrance oil to give your wax a second life.
If you plan to reuse the wax, be sure to let it cool and harden before storing it. Popping the container in the fridge or freezer can help speed up this process. Additionally, if you're combining wax scraps from multiple candles, be sure to strain the wax each time to ensure a clean and pure final product.

Removing wax from the jar
Removing wax from a jar is simple and can be done in a few different ways. One way is to place the jar in a small pot or heatproof container, which is then placed inside a larger pot filled with water. The water is brought to a simmer, and the steam gently melts the wax inside the jar. It is important to ensure that the water does not splash into the jar. Once the wax is fully melted, the jar can be carefully removed, and the wax can be poured out for reuse. This method may take longer than other methods, such as using an oven or a double boiler.
Another method is to use the oven, which is considered a safe and effective way to melt the wax in a glass jar. The oven should be preheated to a low temperature, ideally between 150°F and 170°F (65°C to 75°C). Higher temperatures may cause the glass to crack. The jar is then placed on a baking tray lined with aluminum foil to catch any overflowing wax. The tray is placed in the oven, and the wax is allowed to melt for 10 to 15 minutes. It is important to keep a close eye on the wax to avoid overheating. Once the wax has melted, the jar can be carefully removed from the oven using oven mitts, as it will be hot. The melted wax can then be poured into a mold or another container for reuse.
A third option is to place the jar in the freezer. This causes the wax to shrink and easily pop out of the jar. However, it is important to never use a knife or sharp object to remove wax from a glass jar, as it may scratch or weaken the glass, leading to breakage.
Additionally, it is possible to melt the wax by running hot water over the jar. This method may not be as effective for larger amounts of wax.

Repurposing the wax
Once you've melted the wax, there are several ways to repurpose it. You can pour the melted wax into a mould or another glass jar to create a new candle. Adding a new wick and some fragrance oil can give the wax a second life.
If you're feeling creative, you can make wax melts for use in electric warmers or create homemade fire starters by adding the wax to cotton balls or paper. You can even use the wax in crafting projects like sealing envelopes or making lip balms.
Another idea is to make floral wax sachets. Simply pour the melted wax into a small mould, add a few drops of essential oil and some pressed flowers, and let the wax harden. These sachets make beautiful, fragrant gifts.
If you're combining the remnants of several candles, it's best to use the same type of wax. Different types of wax have different melting points, so some may take longer to melt than others. Wax and soy candles, for example, can be melted together, but they will melt at different speeds and require stirring.
