Candles are a great way to add a cosy, calming atmosphere to any room, but it can be frustrating when they burn unevenly or too quickly. One popular life hack to prevent this is to add salt to the candle wax. This is believed to extend the burn time of the candle, make it burn more slowly and evenly, and reduce smoke and soot. Salt can also be added to the water in which a candle is floating, to prevent the outer layer of wax from melting and keep the candle afloat. However, there are some safety concerns with this method, as salt does not dissolve in wax, and it can be difficult to get the salt to mix properly.

What You'll Learn
Salt can extend a candle's burn time
Salt can be used to extend a candle's burn time. The practice combines traditional rituals with scientific principles. Salt does not dissolve in wax, so it is recommended to dissolve salt in water and then add the saltwater to hot wax. However, this method poses safety risks. An alternative method is to sprinkle salt onto the melted wax around the wick. The salt lowers the melting point of the wax, causing the wax near the wick to melt at a higher temperature and slowing down the overall burning process. This results in a longer burn time and a more stable flame.
A test comparing a tealight candle with salt added and a regular tealight candle showed that the salted tealight burned for 24 minutes longer. The salted tealight also had a longer and stiffer wick, which could impact the performance of larger candles. It is important to trim the wick of salted candles to prevent heavy carbon buildup, which can lead to popping sounds, soot, and undesirable candle burn.
In addition to extending burn time, salt can also reduce soot and smoke, enhance the ambiance by creating a sparkling effect, and improve the aesthetic of the candle. Salt is often associated with purification and protection, making it a common addition to religious and spiritual settings.
Another method to extend a candle's burn time is to create a "shell" barrier by mixing two tablespoons of salt into two cups of water and submerging a new candle in the solution for 24 hours. This causes the candle to melt from the inside out, preventing wax from dripping down the sides.

Salt may cause a larger flame
Salt may have various effects on a candle when added to the wax or wick. One notable effect is the potential increase in burn time, as salt slows down the rate at which the candle wax melts, resulting in a longer-lasting candle. This is achieved by lowering the melting point of the wax near the wick, causing it to melt at a higher temperature and burn more slowly.
However, it's important to note that salt can also impact the size of the flame. In one experiment, a candle treated with salt exhibited a larger flame compared to a regular candle. This effect may be attributed to the salt's influence on the wick. The salt-treated wick was observed to be longer and stiffer, which could lead to a larger flame. While a larger flame can be brighter, an excessively large flame for the candle can become unstable, reducing brightness and generating excessive heat.
The addition of salt to a candle's wick can also contribute to a more stable flame. By reducing irregular melting and burning of the wax, the flame remains steady. This stability is particularly advantageous for decorative or ceremonial candles where a consistent flame is desired. However, it is crucial to trim the wick regularly to prevent heavy carbon buildup, which can lead to popping sounds, soot, and undesirable candle burn.
While the visual appeal of salt-enhanced candles is undeniable, with the creation of a sparkling effect in the flame, it is important to exercise caution. Salt does not dissolve in wax, and its presence can clog the wick, hindering the fuel from reaching the flame. Therefore, it is recommended to treat wicks with salt by dissolving it in hot water and then soaking the wick before letting it dry completely. This process enhances the rigidity of the wick and improves the overall performance of the candle.
In summary, salt may cause a larger flame in candles, but it is important to consider the potential trade-offs. The increase in flame size can enhance brightness, but if the flame becomes too large, it may lead to instability and excessive heat. Additionally, proper wick maintenance and salt application techniques are crucial to ensuring a positive experience and avoiding potential issues with the candle's performance.

Salt can reduce soot and smoke
Salt can be added to candles to extend their burn time and make them burn more slowly and evenly. This is done by sprinkling salt onto the molten wax around the wick. Salt has a high melting point of around 1,474°F (801°C) and does not easily dissolve in wax, so it is recommended to dissolve salt in water first and then add the salt water to the hot wax. However, this method poses safety risks and it is suggested to instead treat the wicks with salt by soaking them in a salt-water solution and letting them dry before use.
Salt can also reduce the production of soot and smoke, leading to a cleaner burn. This is because salt helps to regulate the combustion process, preventing the wick from burning too quickly and reducing the formation of soot and smoke. Salt can contribute to a more stable flame by reducing the irregular melting and burning of the wax. The longer wick created by the addition of salt could, however, cause performance issues in larger candles. A longer wick could eliminate the self-extinguishing curl of some wicks, resulting in a larger flame that is unstable, not as bright, and too hot for the candle.
The addition of salt to candles also has roots in traditional practices and offers aesthetic advantages. In various cultures, salt has been used in rituals and practices involving candles and is often associated with purification and protection. When salt crystals are heated, they can create a gentle sparkle or shimmer effect in the flame, enhancing the visual appeal of the candle.
While adding salt to candles is generally safe, it is important to follow some basic safety precautions. For example, ensuring that the candle is in a heat-safe container or holder to prevent the risk of spilled wax causing a fire hazard. Additionally, it is important to trim the wick regularly to avoid heavy carbon buildup, which can lead to popping sounds, soot, and undesirable candle burn.

Salt can be used to treat wicks
Salt can also be added to the wax around the wick to enhance the candle's burn time, stability, and aesthetic appeal. The salt lowers the melting point of the wax, causing the area near the wick to melt at a higher temperature and slowing down the overall burning process. This results in a longer burn time, reduced soot and smoke, and a more stable flame. However, it is important to regularly trim the wick to avoid heavy carbon buildup, which can lead to popping sounds, excess smoke, and soot.
The amount of salt used is crucial, and it is recommended to use about half a teaspoon of regular table salt or fine sea salt per candle. Coarse or rock salt should be avoided as they may interfere with the candle's burn. When applying salt to a new candle, it is suggested to wait until the candle has formed a melt pool before sprinkling salt onto the wax around the wick. For partially used candles, it is important to ensure the area around the wick is clean and free from excess wax buildup before adding salt.
Salt can also be used to create a "shell" barrier around the candle, preventing wax from dripping down the sides. To achieve this, the candle is submerged in a saltwater solution for 24 hours and allowed to dry completely before lighting. This technique helps the candle melt from the inside out, reducing uneven melting and wax wastage.
While salt can provide benefits such as extended burn time and aesthetic appeal, it is important to be mindful of potential drawbacks. For example, in larger candles, a stiff wick caused by salt treatment may eliminate the self-extinguishing curl of some wicks, resulting in a larger flame that is unstable and too hot for the candle. Therefore, it is crucial to consider the type of candle and follow safety precautions when using salt to treat wicks.

Salt candles have roots in traditional practices
Salt candles are also said to extend the burn time of candles. This is because salt slows down the rate at which the candle wax melts, thus making the candle last longer. Salt also helps to regulate the combustion process, preventing the wick from burning too quickly and reducing the formation of soot and smoke.
The technique of adding salt to candles is simple and requires only a small amount of salt, making it an accessible way to enhance your candles. It is recommended to use regular table salt or fine sea salt. Avoid using coarse or rock salt as they might not melt as effectively and could interfere with the candle's burn. You only need a small amount, usually about half a teaspoon per candle.
To add salt to a candle, first light the candle and let it burn for a few minutes until a small pool of liquid wax forms. Then, add the salt to this liquid wax. Using a toothpick or a small tool, gently stir the salt into the melted wax to help it dissolve and spread evenly around the wick area. Be careful not to disturb the wick's position. Allow the candle to burn normally, and you should notice a slower burn rate and a reduction in soot and smoke.
Salt candles are also said to have a symbolic meaning in some traditions. For example, in Wicca, a circle of salt around a candle is not standard practice but may be done for symbolic reasons specific to a particular ritual. Salt is sometimes used to represent the element of Earth, and a circle of salt can also be used for protection or to contain something, with the idea that the salt creates a barrier. In New Year rituals, salt water is used to symbolize deep cleansing and purification, helping to wash away old energies and make space for new beginnings.
