What Happens to Candle Wax While Burning?
Candles are a warm, inviting way to set the mood in any space, but have you ever wondered about the science behind the burning process? How does candle wax transform as it melts, and where does it go? Understanding the process of candle wax combustion can deepen your appreciation for this simple yet magical source of light and fragrance. In this article, we will dive into the fascinating science of what happens when you burn a candle, explore the properties of different types of wax, and offer tips on how to make your candles last longer.
The Science Behind Candle Wax Combustion
Candle wax, usually made from hydrocarbons, is composed of carbon atoms bonded with hydrogen atoms. These hydrocarbon molecules are designed to burn completely, providing both heat and light. When you light a candle, the heat from the flame begins to melt the solid wax surrounding the wick, transforming it into a liquid. But what happens next?
How Candle Wax Burns
The burning process starts with heat from the flame vaporizing the wax's hydrocarbon molecules. These molecules react with the oxygen in the air, undergoing combustion. This reaction produces carbon dioxide, water vapor, and heat, which radiates from the flame. The heat vaporizes more wax, continuing the combustion process.
The wick plays a crucial role in this process. Through a phenomenon known as capillary action, the wick draws the liquid wax upwards, defying gravity and feeding the flame with a continuous supply of wax. As long as the wax is in contact with the wick, the candle will continue to burn efficiently.
One of the most fascinating aspects of candle combustion is that there is no ash or residue left behind. The combustion process is efficient enough that the wax is completely consumed, leaving only the light and heat emitted by the flame.
The Chemical Equation of Candle Wax Combustion
While the specific chemical equation can vary depending on the type of wax used, the general formula looks something like this:
C25H52 + 38 O2 → 25 CO2 + 26 H2O
In simpler terms, when the wax is heated, it reacts with the oxygen in the air to produce carbon dioxide (CO2), water vapor (H2O), and heat. This process is responsible for the candle's light and warmth.
How Different Types of Wax Affect the Burn
While many candles use paraffin wax, there are various other options available. At Aarka Origins, we proudly use natural soy wax for our hand-poured candles, ensuring a cleaner, eco-friendly burn. Soy wax is a renewable, carbon-neutral resource that provides a longer-lasting burn compared to paraffin. Plus, it’s non-toxic and phthalate-free, making it a healthier choice for your home and the planet.
If you're interested in a natural, environmentally conscious option, we recommend trying the The Misty Mountains Soy Candle or Through the Wardrobe Soy Candle.
Does Candle Wax Evaporate Into the Air?
As you watch your candle burn, you might wonder: Is the wax vapor that rises from the flame harmful to breathe? The answer is no. While it may seem like the wax evaporates into the air, it’s actually being converted into carbon dioxide and water vapor. These substances are completely safe to inhale in small quantities.
However, it’s essential to note that a flickering flame can cause incomplete combustion, resulting in the release of soot and smoke. This is why it’s important to maintain a steady, teardrop-shaped flame, which ensures a clean burn and prevents unnecessary waste of wax.
At Aarka Origins, we carefully design our candles to burn smoothly and consistently, allowing you to enjoy the full experience of the scent and flame. For a cozy, long-lasting burn, try our March Family Christmas Soy Candle or the delightful Witchy Bakery Service Soy Candle.
Tips for Extending Your Candle’s Burn Time
To ensure you get the most out of your candle, here are a few helpful tips:
1. Trim the Wick Regularly
A wick that’s too long can lead to a larger flame, causing your candle to burn too quickly and unevenly. Trim the wick to about ¼ inch before lighting it to promote an even burn and to avoid unnecessary soot production.
2. Let the Wax Melt Completely
Allow your candle to burn long enough for the entire surface of the wax to melt. This helps prevent the formation of a “tunnel” in the wax, where the wick burns down in the center, leaving excess wax on the sides.
3. Burn in Draft-Free Areas
To avoid uneven burning or flickering, burn your candle in a draft-free area. This will help the flame remain steady and promote an efficient burn.
