There is an ongoing debate about whether candles can freeze and if doing so would make them burn longer. Some believe that freezing candles can extend their burn time, while others consider this to be an old wives' tale. Freezing candles may cause them to crack, and the temperature changes can cause the wax to contract, pushing out the oils used to scent the candle. While candles can become harder in cold temperatures, they do not freeze in the same way that water does, and the burn time of a candle is dependent on its composition and wick size, rather than storage temperature.

What You'll Learn
Freezing candles may cause cracks
Freezing candles has been a topic of debate for candle enthusiasts. Some believe that it helps candles stay fresh and burn longer, while others consider it a bad idea. One of the main concerns with freezing candles is the possibility of cracking.
When candles are subjected to extremely fast temperature changes, such as being placed in a freezer, the wax contracts. This contraction can cause the candle to crack, especially if it has been in the freezer for an extended period. The rapid change in temperature affects the candle's core, and as the outside of the candle warms faster than the inside when removed from the freezer, it can lead to cracks in the wax.
Additionally, moisture can get into the wick of a candle during freezing, which may cause further issues during burning. A cracked candle may not burn evenly or even at all due to the impact of freezing on the wick and wax. The liquid wax may start to drain out of the cracked areas, making it challenging for the candle to burn properly.
The type of candle and its wax composition can also influence the likelihood of cracking. For example, pillar candles and votive candles may be more prone to cracking due to the nature of their wax and structure. On the other hand, taper candles and jar candles might be less likely to crack due to their softer wax or the containment provided by the jar.
While some people argue that freezing candles can extend their burn time by slowing down the melting process, the presence of cracks can counteract this potential benefit. The cracks can affect the structural integrity of the candle, impacting its ability to burn evenly and efficiently. Therefore, it is generally recommended to store candles in a cool, dark space like a cupboard or closet to maintain their quality and avoid the risk of cracking due to extreme temperature changes.

Freezing candles may cause loss of fragrance
Freezing candles has been a topic of debate for many years, with some believing it to be an effective way to preserve them. However, one potential downside of freezing scented candles is the possibility of fragrance loss.
When scented candles are subjected to freezing temperatures, the wax undergoes rapid temperature changes, causing it to contract. This contraction forces out the oils that give the candle its scent. As the candle returns to room temperature, the expelled oils may appear as small water droplets on its surface. While the candle will still retain some fragrance, the intensity will be diminished compared to its original state.
The extent of fragrance loss can vary depending on factors such as the candle's wax composition and the freezing temperature. Different types of wax, such as paraffin, soy, and beeswax, have unique freezing points influenced by their molecular structure. In extremely cold climates, candles may become harder and more brittle, increasing the likelihood of fragrance loss.
To avoid fragrance loss and potential cracking of the candle, it is recommended to store unused candles in a cool, dark space like a cupboard or closet. This storage method ensures the candle remains protected from rapid temperature changes while preserving its scent and structural integrity.
While freezing candles may not cause complete fragrance loss, it is evident that it can lead to a reduction in scent intensity. Therefore, it is advisable to explore alternative storage methods to maintain the optimal condition of scented candles.

Freezing candles may not increase burn time
Freezing candles is thought to make them last longer, but there are several reasons why this may not be the case. Firstly, the process of freezing and thawing can cause the candle to crack, which may prevent it from burning evenly or at all. This is due to the extremely fast temperature changes causing the wax to contract, and it can also cause the oils used to scent the candle to be pushed out of the wax.
Another reason freezing candles may not increase their burn time is that when a candle is lit, only a small portion of the outside of the candle is melted. The flame of a candle typically burns at around 2500 degrees Fahrenheit, which is hot enough to quickly melt the wax around it, undoing any effects that freezing may have had. By the time the flame reaches the core of the candle, it will have long lost any effects of freezing.
The burn time of a candle is primarily dependent on its composition and the size of its wick, rather than the temperature at which it was stored. While freezing may slightly affect the hardness of the wax, it does not undergo a conventional solidification process like water. Therefore, freezing candles may not have a significant impact on their burn time.
Some people believe that freezing candles can extend their burn time, but this may be nothing more than an old wives' tale. Freezing candles can also take up valuable freezer space, which could be better used for other items such as food. Overall, while freezing candles may have some minor effects on their appearance and scent, it is unlikely to significantly increase their burn time.

Freezing candles may cause wax to contract
Freezing candles has been a topic of debate for candle enthusiasts, with some believing it helps them stay fresh and last longer. However, the idea that freezing candles will make them burn slower is just an old wives' tale. Freezing candles may cause the wax to contract, leading to several issues.
Firstly, when candles are subjected to extremely fast temperature changes, the wax contracts rapidly. This causes the wax to crack, especially if left in the freezer for an extended period. The cracks can range from small fractures to large splits, depending on the type of candle and the duration of freezing. These cracks can render the candle unusable as the liquid wax will drain out of the damaged areas when lit.
Additionally, the rapid temperature change can also affect the scent of scented candles. The temperature fluctuations force out the oils used for fragrance, resulting in a loss of scent or a diminished fragrance intensity. As the candle returns to room temperature, the oil residue may appear as small water droplets on the surface, which disappear once the candle is lit.
The process of freezing candles may also introduce moisture to the wick, which can further impact the candle's performance. This moisture can interfere with the burning process, causing uneven burning or, in some cases, preventing the candle from lighting at all.
While some believe that freezing candles will make them burn slower, this is not the case. When a frozen candle is lit, only a small portion of the outside wax is melted, and the flame does not immediately affect the colder core. However, as the candle continues to burn, the surface area around the flame quickly warms up above room temperature, negating any potential impact of the freezer.
In conclusion, freezing candles may cause wax to contract, leading to cracking, loss of fragrance, and wick damage. These issues can affect the aesthetics and functionality of the candle. Therefore, it is recommended to store unused candles in a cool, dark space, such as a cupboard or closet, to maintain their condition and performance.

Freezing candles may cause condensation
Freezing candles is believed to extend their burn time. The rationale is that since the wax is colder, it will take longer to reach the bottom of the candle. However, this is just an old wives' tale. Freezing candles may cause condensation, resulting in the formation of small water droplets on the candle's surface as it returns to room temperature. This phenomenon occurs due to the extremely fast temperature changes that the wax undergoes during the freezing and thawing process.
When a candle is placed in a freezer, it will eventually reach temperatures below freezing, causing the wax to undergo significant changes. The wax contracts, and if left in the freezer long enough, it will get cold to its core. As the candle is removed from the freezer and begins to thaw, the outside of the candle warms faster than the inside, leading to rapid temperature swings.
These rapid temperature changes can cause condensation on the candle's surface. As the candle warms, the wax near the surface melts, and the liquid wax draws heat from the surrounding air, resulting in a cooling effect. This cooling effect can lead to the formation of condensation on the candle's surface, similar to how water droplets form on a cold drink on a hot day.
Additionally, the presence of fragrance oils in scented candles can further contribute to the formation of condensation. During freezing, the wax contracts, pushing out the oils used for scenting. As the candle warms up, the oils can migrate back towards the surface, mixing with the water vapour formed due to the temperature changes. This mixture of oil and water vapour then condenses on the candle's surface, forming visible water droplets.
To avoid condensation on your candles, it is recommended to store them in a cool, dark space like a cupboard or closet. This way, you can maintain their freshness without subjecting them to the extreme temperature changes of freezing.

Frequently asked questions
Candle wax does not freeze in the same way that water does. While water freezes at 0°C (32°F), waxes gradually harden at much lower temperatures. In most human habitats, the temperature will not be low enough for candle wax to freeze.
Freezing candles will not make them burn longer. When a candle is lit, only a small portion of the outside of the candle is melted. The flame of a candle is not hot enough to pull wax from the colder core of the candle. As the wax melts, it will heat up more of the candle's surface faster than if the candle was unlit.
When you freeze a scented candle, the wax undergoes extremely fast temperature changes, causing the wax to contract. This pushes out the oils used to scent the candle. As the candle warms up, you will see small water droplets form on top of the candle, which will disappear when the candle is lit. The candle will still have a scent, but it won't be as strong.
Freezing candles in glass jars can cause the glass to become more brittle and crack. However, some people have frozen glass jars without issues. Gradual temperature changes are key to preventing the glass from cracking.
