Freezing candles is a popular hack to extend their lifespan. While some believe freezing candles can make them burn slower, others think it is an old wives' tale. Freezing candles can cause the wax to crack, especially when exposed to rapid temperature changes. To avoid this, it is recommended to only freeze candles for a short time before lighting them. There are mixed opinions on how long to freeze a candle, with some suggesting 6 to 8 hours, while others claim that even 20 minutes is sufficient. Freezing candles can also help remove excess wax for repurposing.

Freezing candles to extend their lifespan
There are several ways to extend the lifespan of your candles. One popular method is to freeze them. Freezing candles is believed to extend their burn time, as the cold wax takes longer to melt. However, there are conflicting opinions on the effectiveness of this method. While some people swear by it, others consider it an old wives' tale.
To test this theory, two identical candles were used in an experiment. One was placed in a freezer, while the other remained at room temperature. The frozen candle was left in the freezer for over 24 hours, which is longer than the recommended six to eight hours. After removing the candle from the freezer, its wick was trimmed, and it was lit alongside the room-temperature candle.
During the first five minutes of burning, there was no noticeable difference between the two candles. However, after one and a half hours, it appeared that the unfrozen candle was burning slightly faster. The experiment concluded that the frozen candle lasted an extra five hours, confirming that freezing candles can indeed extend their lifespan.
It is important to note that freezing candles for too long may cause cracking or splitting, especially when exposed to rapid temperature changes. Therefore, it is recommended to freeze candles for a shorter duration, just enough to chill them before lighting. Additionally, freezing scented candles may cause the wax to contract, pushing out the oils used for scenting. As a result, the fragrance may be lost when the candle returns to room temperature.
Another way to extend the lifespan of your candles is to sprinkle salt into the wax as it melts. This slows down the rate of melting, allowing you to enjoy your candles for a longer period. Additionally, always ensure you burn your candles long enough to create a pool of melted wax across the entire top. This prevents tunneling, which leaves extra wax around the edges, reducing the lifespan of your candle.

The optimal freezing time for candles
Freezing candles is a popular life hack to make them last longer. The science behind this hack is that placing candles in the freezer before lighting them should make them burn slower since the wax is colder. However, there are conflicting opinions on whether freezing candles actually extend their lifespan.
Some people believe that freezing candles can cause the wax to crack, split, or lose their scent. This typically happens due to the rapid temperature change when the candle is removed from the freezer and exposed to room-temperature air. Moisture can also get into the wick, causing the candle to burn unevenly or not at all. Therefore, it is recommended to freeze candles for only a short time before lighting them, instead of storing them in the freezer for extended periods.
There is no definitive answer to how long candles should be frozen. Some sources suggest freezing them for a couple of hours, while others recommend six to eight hours. One experiment froze the candle for over 24 hours for noticeable results. Ultimately, the optimal freezing time for candles may vary depending on the type of candle, the temperature of the freezer, and other factors.
To freeze a candle, place it in the freezer for the desired amount of time. When you remove it from the freezer, you will notice that it has gained an icy exterior. Let it thaw for a few minutes, and then trim the wick to the desired length. Although freezing candles may not significantly extend their burn time, it is still a useful hack to remove excess wax from old candles for repurposing.
In conclusion, while freezing candles may not always result in a longer burn time, it is a simple and cost-effective hack that can be worth trying. The optimal freezing time varies, but a good range seems to be between two and 24 hours, depending on the desired results and the type of candle. Remember to let the candle thaw and trim the wick before lighting it, and always be cautious when handling frozen items to avoid any accidents.

How to avoid candle cracks when freezing
Freezing candles is a common practice to keep them fresh until use. However, it is important to note that freezing can cause candle cracks due to rapid temperature changes. Here are some ways to avoid candle cracks when freezing:
Maintain a Steady Room Temperature
Keep your candles at a steady room temperature of around 18°C to 20°C during the cooling process. Avoid extreme temperature swings, especially when freezing, as this can cause the wax to contract and crack.
Pre-heat Candle Vessels
Pre-heat your candle vessels or moulds before pouring the wax. This helps slow down the cooling process and prevents rapid cooling, which can lead to cracks.
Avoid Filling Before Wax Solidifies
Ensure that the wax has completely solidified before filling the well of the candle. Filling the well too early, before the wax has set, can result in cracks.
Gradual Temperature Changes
When freezing candles, avoid sudden temperature changes. Gradually cool the candles by placing them in the fridge or using cold water to acclimate them to lower temperatures before putting them in the freezer.
Stir Slowly
When preparing the wax, stir slowly and smoothly. Excessive or vigorous stirring can create small air bubbles that get trapped during cooling, leading to cracks or bursting.
Fill in Cracks
If cracks do occur, you can fill them in by melting the surface slightly or using leftover wax. Tap out any air bubbles before filling to ensure a smooth finish.
By following these steps, you can help prevent candle cracks when freezing and ensure your candles remain intact and burn evenly.

Freezing candles to remove excess wax
If you want to remove excess wax from a candle jar, freezing is a good method. It is safer and more convenient than other methods such as melting wax with a hairdryer or using boiling water.
The amount of time you'll need to freeze a candle to remove excess wax depends on the type of wax used. For soft wax, a couple of hours should be enough, but harder wax may require more time. Freezing the wax causes it to shrink and loosen, making it easier to remove.
To freeze a candle to remove excess wax, follow these steps:
- Set the candle in the freezer, preferably overnight for best results.
- The next day, take the container out of the freezer and flip it upside down. The lump of wax should pop right out.
- If the wax doesn't come out easily, use a spoon or butter knife to gently loosen it from the sides of the jar and lift it out.
- If the wax is still difficult to remove, place the candle back in the freezer for another hour or two.
It's important to note that freezing may not work as well for harder waxes, and some people recommend trying other methods first, such as melting the wax with boiling water. Additionally, if you're freezing a candle in a glass container, gradual temperature changes are recommended to avoid shattering the glass.

Other ways to make candles last longer
While some sources suggest that freezing candles can make them last longer, others argue that the effect of freezing is undone once the candle returns to room temperature. In addition, candles can crack when subjected to fast temperature swings, which may prevent them from burning evenly or at all.
Trim the wick
Trimming the wick to about a quarter of an inch before each burn can help to prevent large flames, sooty smoke, and uneven burning. It also prolongs the candle's life by allowing it to burn steadily.
Burn for limited periods
Limit each burn session to around three to four hours. Burning a candle for too long can cause the wick to "mushroom", resulting in a larger flame, soot, and excessive heat.
Avoid drafty areas
Keep candles away from vents, fans, drafts, and areas of the house that tend to be drafty. Air currents can cause uneven burning and may blow out the flame or knock the candle over.
Allow wax to liquify
Allow the candle to burn long enough for the wax to liquify and reach the edges of the container. This prevents "tunneling", where wax builds up on the sides, leaving unused wax behind.
Sprinkle with salt
After burning a candle long enough to collect a pool of wax around the wick, sprinkle in some table salt and mix with a toothpick. Salt slows down the rate of wax melting, increasing the lifespan of the candle.
