Why Does Salt Make Candles Burn Longer?

The Science Behind Salt and Candles

Candles have been used for centuries for religious, decorative, and practical purposes. However, have you ever wondered why adding salt to a candle can make it burn longer? The answer lies in the science behind the burning process. When a candle burns, the heat from the flame melts the wax, which then flows up the wick and evaporates. The evaporated wax reacts with oxygen in the air to produce heat and light. However, the heat from the flame can also melt the wax too quickly, causing the candle to burn out faster. This is where salt comes in. Salt is a natural flame retardant, which means it can slow down the burning process. When salt is added to the wax, it forms a barrier around the wick, which slows down the melting process and allows the wax to burn at a slower rate. As a result, the candle burns longer.

The Benefits of Using Salt in Candles

Aside from making candles burn longer, using salt in candles has other benefits as well. For one, it can help reduce the amount of soot and smoke produced by the candle. This is because the salt helps regulate the burning process, which reduces the amount of carbon buildup in the wax. In addition, using salt in candles can also help enhance the scent of the candle. This is because the salt helps to distribute the fragrance more evenly throughout the wax, which results in a stronger and longer-lasting scent.

How to Make Salt Candles

If you’re interested in making your own salt candles, it’s actually quite easy to do. Here’s a simple recipe to get you started: Ingredients: – 1 pound of candle wax – 1 tablespoon of salt – Candle wicks – Candle dye (optional) – Essential oils (optional) Instructions: 1. Melt the candle wax in a double boiler over low heat. 2. Once the wax is melted, add the salt and stir until it’s fully dissolved. 3. If you’re using candle dye, add a few drops until you reach the desired color. 4. If you’re using essential oils, add a few drops until you reach the desired scent. 5. Pour the wax into the candle containers and insert the wicks. 6. Allow the candles to cool and harden for several hours. 7. Trim the wicks and enjoy your new salt candles!

The Bottom Line

In conclusion, adding salt to candles can help make them burn longer, reduce soot and smoke, and enhance the scent. Whether you’re making your own candles or simply looking for ways to get more out of your store-bought candles, adding a pinch of salt is a simple and effective solution. So next time you light a candle, remember the science behind salt and the benefits it can bring.
