Put the candle in the freezer to remove the wax
If your candle glass breaks, it is unsafe to continue burning it. Heated glass risks exploding, especially if there are already cracks or breaks. Using a broken candle risks glass lacerations or even burning down your house. Therefore, it is best to remove the wax from the broken glass and transfer it to another container.
One way to do this is by putting the candle in the freezer. The cold temperature will cause the wax to shrink and loosen, making it easier to remove. Here are the steps you can follow:
- Set the candle in the freezer and leave it for at least 3-5 hours or preferably overnight for the best results. The colder the temperature, the better.
- After removing the candle from the freezer, turn it upside down. The lump of wax should pop right out. If not, gently tap or shake the container to help dislodge the wax.
- If the wax is still stuck, use a spoon or butter knife to slowly and carefully loosen it from the sides of the container. Be gentle to avoid breaking the glass further.
- If necessary, place the candle back in the freezer for another hour or two, then try again.
It is important to note that freezing may not work for all types of wax. Some harder waxes may require additional softening methods, such as using boiling water or a hairdryer. Additionally, be cautious when handling broken glass, as it can have sharp edges. Always wear protective equipment, such as gloves and eye protection, when working with broken glass.

Use a strainer to separate the wax from the glass shards
If your candle glass breaks, it is important to act with caution. Burning a candle in a broken glass container can be dangerous, as the heat could cause the glass to shatter further, potentially causing lacerations or even starting a fire.
One way to safely remove the wax from a broken candle jar is to use a strainer to separate the wax from the glass shards. Here is a step-by-step guide:
- Put on protective gear: Before handling the broken candle, it is important to put on protective gear to avoid injuries. Wear plastic gloves to protect your hands and arms from cuts, and consider eye protection to shield your eyes from any flying glass shards.
- Melt the wax: Place the broken candle jar in a pot of hot water, ensuring that the water level is below the broken glass. Turn on the heat and let the water simmer. This will melt the wax, making it easier to separate from the glass.
- Use a strainer: Once the wax is melted, carefully pour the contents of the candle jar into a strainer. The strainer will catch the larger pieces of glass, allowing the liquid wax to pass through. Be cautious when handling the hot wax to avoid burns.
- Filter the wax: After straining out the larger pieces of glass, you may need to filter the wax to remove any fine glass shards that may have passed through the strainer. Use a fine-mesh strainer or cheesecloth to carefully strain the wax a second time, ensuring that all glass fragments are removed.
- Dispose of the glass shards: Properly dispose of the collected glass shards in a secure container, such as a small bag or box. Mark the container clearly to indicate that it contains broken glass to avoid accidental injuries.
- Transfer the wax: Once the wax has been strained and filtered, carefully transfer it to a new container. You can pour the liquid wax into a new candle jar or mold to create a new candle. Alternatively, you can use the wax in a wax warmer or to make wax melts.
By following these steps, you can safely separate the wax from the broken glass shards and either reuse the wax or dispose of it appropriately. Remember to always exercise caution when handling broken glass and hot wax to prevent injuries.

Melt the wax in a pot of boiling water
If your candle glass breaks, it is unsafe to continue burning the candle. Heated glass risks exploding, especially if there are already cracks or breaks.
One way to salvage the wax from a broken candle is to melt it in a pot of boiling water. Here is a step-by-step guide:
- Gather your supplies: You will need a pot, a pair of plastic gloves, an oven mitt or towel, and some tweezers. These supplies will help prevent wax from getting on your hands and protect you from cuts and burns.
- Remove large pieces of broken glass: Using tweezers, carefully take out the larger pieces of broken glass from the candle wax. You can use napkins to wipe off the glass and make the process easier.
- Fill the pot with water: Fill the pot with enough water to reach just below the lowest part of the broken glass. This level of water ensures that the water will not mix with the candle wax.
- Heat the water: Turn on the heat and let the water simmer. The hot water will help melt the wax and release it from the glass.
- Add the candle to the pot: Once the water starts boiling, carefully place the candle in the pot. The hot water will melt the bottom layer of the candle, allowing the wax to separate from the glass.
- Optional: Transfer the wax: If you wish, you can transfer the melted wax to another container. Repeat the water bath process until all the wax is melted.
- Pour the wax: Pour the melted wax into a new candle container, glass, or ice cube tray to make wax melts.
It is important to note that this method may not be suitable if the glass is shattered into very small pieces, as it can be difficult to separate all the pieces from the wax. In such cases, it may be necessary to explore other methods, such as freezing the candle to make the wax contract and separate from the glass.

Pour the melted wax into a new container
If your candle glass breaks, it is unsafe to continue burning it. Heated glass can explode, and the cracks or breaks can cause glass lacerations or even start a fire. Instead, you can pour the melted wax into a new container to create a new candle. Here is a step-by-step guide:
- First, you need to remove the wax from the broken glass. One way to do this is by freezing the candle. Wrap the candle in a few layers of disposable bags, such as grocery bags, and put it in the freezer. The wax will contract, making it easier to separate from the glass. You can also try placing the candle in hot water to melt the bottom layer of wax, which may allow you to lift it out by gently pulling the wick.
- Once the wax is frozen or melted, use a knife or a pair of tweezers to carefully remove the broken pieces of glass. Be very cautious to avoid any cuts. You can also use napkins or a damp piece of kitchen roll to wipe off any remaining glass shards.
- If there are still large chunks of wax attached to the glass, you can try the hot water method. Fill a pot with water and place it on the stove. Bring the water to a simmer. Place the wax in a ziplock baggie and then place the baggie in the hot water. The wax will melt, and you can use a small strainer to catch any loose glass as you transfer the melted wax into a safe container.
- Alternatively, you can use a double boiler method. Place the wax in a heat-safe container and add water to a pot. Bring the water to a boil and then place the container with the wax inside the pot. The indirect heat will melt the wax, and you can then pour it into a new container.
- Choose a new container that is similar in size to the original candle jar. Make sure the new container is heat-safe and can withstand the temperature of the melted wax.
- Once you have removed all the broken glass and strained the wax to remove any small shards, you can pour the melted wax into your new container. Be careful not to spill the hot wax on yourself.
By following these steps, you can safely transfer the melted wax from a broken candle into a new container, creating a new candle to enjoy.
