There are several methods to repurpose old candles and candle holders. One way is to freeze old candles for a few hours to easily remove excess wax. However, there is an ongoing debate about whether freezing candles is a good idea. Some believe that freezing candles can extend their burn time, while others think it is a myth. Freezing candles can cause them to crack, split, or lose their scent. It is recommended to freeze candles for a short time before lighting them to avoid these issues.

What You'll Learn
Candles may crack when frozen due to rapid temperature changes
Freezing candles is a popular topic of discussion, with some sources claiming that it helps preserve them, while others argue that it can cause cracking and uneven burning. The latter is due to the rapid temperature change that occurs when a candle is removed from a freezer and begins to return to room temperature.
When a candle is frozen, it will eventually reach the same temperature throughout, from the outer surface to its core. However, as it is taken out of the freezer and starts to thaw, the outside of the candle warms up faster than the inside. This rapid temperature change can cause the candle wax to crack. The speed of temperature change can also cause moisture to form in the candle's wick, which may prevent the candle from burning evenly or at all.
The type of wax and the presence of additives can also influence how a candle reacts to freezing. For example, paraffin wax, a common choice for candles, has a melting point ranging from 120°F to 135°F, depending on its purity and any additives. Soy wax, on the other hand, is known for its slower melting rate. Different types of wax and additives will affect the freezing point and how the wax reacts to temperature changes.
Additionally, the fragrance of a candle can be affected by freezing. The rapid temperature change can cause the oils used for scenting to separate from the wax and collect on the candle's surface or inside the glass, resulting in a less fragrant candle.
To avoid potential issues with freezing, it is recommended to store unused candles in a cool, dark space, such as a cupboard or closet, to maintain their scent and burning capabilities.

Freezing a candle will not make it burn longer
Freezing a candle is believed to extend its burn time. The logic behind this is that since a candle is used up only when the wax liquefies and burns, freezing it will make it take longer to melt. However, this is just an old wives' tale. Freezing a candle will not make it burn longer.
When a candle is removed from the freezer, it will begin to return to room temperature. The outside of the candle will warm faster than the inside. When a candle is lit, only a small portion of the outside of the candle is melted, and the flame does not pull wax from the colder center. The temperature of a candle flame, depending on the type of wax and wick, can reach about 2500 degrees Fahrenheit, which is much higher than the melting point of candle wax. Thus, the surface area of the candle around the flame will rapidly heat up, quickly undoing any effect the freezer may have had. By the time the center of the candle is reached, the effect of the freezer will have long worn off.
In addition, freezing a candle can cause it to crack. Candle wax cracks when subjected to rapid temperature changes. A cracked candle may not burn evenly or at all. This is because moisture can get into the wick from freezing.
For scented candles, freezing can cause the fragrance to be squeezed out of the wax, leaving oil around the inside of the glass and on top of the candle. Thus, freezing a candle will not make it burn longer and can even cause adverse effects.

Thicker candles may need 6-8 hours in the freezer
There are mixed opinions about freezing candles to increase their lifespan. Some believe that placing candles in the freezer can make them burn slower, as the wax will take longer to melt because it is cold. However, others argue that this is just an old wives' tale.
If you want to try this method, it is important to consider the thickness of your candle. Thicker candles will need more time in the freezer than thinner ones. For a thicker candle, aim for between 6 and 8 hours in the freezer. This will ensure that the wax is cold all the way through, potentially slowing down the melting process once the candle is lit.
However, it is worth noting that there are risks associated with freezing candles. One of the main concerns is that the candle may crack due to rapid temperature changes. This is more likely to occur with thicker candles, as they need to spend more time in the freezer. Candles with cheaper or thinner glass may also break due to the brittleness caused by freezing.
Additionally, some people have reported that freezing a candle can affect its scent, causing the fragrance to be squeezed out of the wax and leaving oil inside the glass. Therefore, it may be best to only freeze your candles for a short time before lighting them, rather than keeping them in the freezer permanently.

Freezing candles may cause them to lose their scent
Freezing candles is a popular topic of discussion, with some sources claiming that it helps preserve them and makes them burn longer, while others refute these claims. One reason for freezing candles is to remove excess wax for repurposing the candle container. However, freezing candles may not be advisable if you want to preserve their scent.
Firstly, it is important to understand that candles do not spoil like food or drinks, but they can expire and lose their scent over time. The fragrance oils in candles can break down, causing a decrease in scent intensity. Exposure to air, heat, and light can cause these oils to degrade, and UV rays can also cause the candle colour to fade. Therefore, proper storage is crucial for preserving a candle's scent. It is recommended to store candles in a cool, dry place, away from direct sunlight and humidity. Keeping them covered or in airtight containers can also help maintain their fragrance.
Freezing candles may not be the best method for scent preservation. Cold temperatures can affect scent quality, and there is a risk of the candle cracking due to rapid temperature changes. When removed from the freezer, the outside of the candle warms faster than the inside, and the small portion of the outside that is melted during burning is not significantly affected by the freezing temperature. Additionally, the fragrance may be squeezed out of the wax, leaving oil residue inside the glass and on top of the candle.
Instead of freezing, it is suggested to burn candles within a year of purchase for the best fragrance experience. Burning a candle for 3 to 4 hours on the first use is recommended to ensure an even wax melt and optimal fragrance release. For scented candles, it is also crucial to consider factors such as the type of wax, fragrance, fragrance load, and storage conditions, as these can impact the scent's longevity.

Freezing a candle can help it burn more evenly
Freezing candles is a popular method to increase their lifespan and burn them more evenly. While some believe it is a useful hack, others think it is just an old wives' tale. Freezing a candle can help it burn more evenly by slowing down the melting process. This is because the wax is colder and harder, which causes it to melt at a slower rate.
The thinner the candle, the less time it needs to spend in the freezer. A thicker candle may need between six to eight hours, while a thin, tapered candle may only need an hour. However, it is important to note that freezing a candle for too long can cause it to crack or split due to rapid temperature changes. This may affect the evenness of the burn. Therefore, it is recommended to only freeze candles for a short time before lighting them.
There are mixed opinions about freezing candles to increase their burn time. Some people believe that freezing candles can help them burn slower and last longer. They argue that since the wax is colder, it will take longer to melt and reach the bottom of the candle. This can save money in the long run, as you won't need to buy new candles as often.
However, others argue that freezing candles do not significantly affect their burn time. They explain that when a candle is lit, only a small portion of the outside of the candle is heated and melted. The flame does not immediately pull wax from the colder center. As the candle burns, the surface area around the flame quickly warms up, undoing the effect of freezing. By the time the center of the candle is reached, it will have lost the effect of freezing, resulting in a similar burn time as a non-frozen candle.
It is worth noting that while freezing candles may not significantly increase their burn time, it can still be useful for removing excess wax from candle jars or tins. By freezing the candle, the wax becomes easier to remove, allowing for the repurposing of the container.
