How Candles Work

Candles have been a source of light and warmth for centuries, but have you ever wondered exactly how they work? Understanding the basic mechanics of candle burning can enhance your appreciation for these timeless items and ensure you get the most out of every candle you burn.

When you light a candle, you set in motion a fascinating process that combines science and artistry. At the heart of this process is the wick, the thin string that runs through the center of the candle. The wick is the key player in the combustion process that fuels the candle’s flame.

Components of a Candle

To fully grasp where the wax goes when you burn a candle, it’s important to understand the key components that make up a candle:

  1. Wick: The wick is typically made of braided cotton. When you light the wick, it heats up and starts the melting and combustion process.
  2. Wax: The wax acts as the fuel for the candle.
  3. Fragrance: Many candles, including those from Starling Petals, contain fragrances that are released as the candle burns, creating a pleasant aroma.

When the wick is lit, the heat from the flame melts the wax near the wick. This melted wax is then drawn up the wick through capillary action. As the liquid wax moves up the wick, it gets close to the flame, where it vaporizes and combusts, producing heat, light, water vapor, and carbon dioxide. This process continues until all the wax around the wick is consumed, and the flame extinguishes itself.

How Candles Work: A Step-by-Step Process

  1. Lighting the Wick: The initial flame melts the wax at the top of the candle.
  2. Melting the Wax: The heat of the flame melts the solid wax into liquid wax.
  3. Capillary Action: The liquid wax is drawn up the wick by capillary action.
  4. Vaporization: As the liquid wax travels up the wick, it gets close to the flame and vaporizes.
  5. Combustion: The vaporized wax reacts with oxygen in the air to combust, producing heat, light, water vapor, and carbon dioxide.

Understanding these basic principles can help you appreciate the careful craftsmanship that goes into each Starling Petals candle. Not only does this knowledge enhance your candle-burning experience, but it also underscores the importance of proper candle care to ensure a safe and efficient burn.

The Science Behind Candle Burning

Melting of Wax

When you light a candle, the first thing that happens is the melting of the wax near the wick. This melting is crucial for the candle to burn properly. The heat from the flame liquefies the solid wax, creating a pool of molten wax around the wick. This liquid wax is essential because it acts as the fuel for the flame.

The type of wax used in a candle can affect how it melts and burns. At Starling Petals, we use high-quality soy wax, known for its clean-burning properties and longer-lasting burn. Soy wax melts at a lower temperature compared to other waxes, making it safer and more efficient.

Capillary Action

Once the wax is melted, the liquid wax is drawn up the wick by a process known as capillary action. This is the same process that allows plants to draw water up through their roots and stems. In a candle, capillary action occurs because the wick is made of porous material, typically braided cotton, that pulls the liquid wax upward.

As the liquid wax travels up the wick, it gets closer to the flame. The heat from the flame continues to draw more liquid wax up through the wick, creating a continuous supply of fuel for the flame. This process is crucial for keeping the candle burning steadily and evenly.

Evaporation and Combustion

When the liquid wax reaches the flame, it vaporizes due to the intense heat. This vaporization turns the liquid wax into a gas, which is then able to combust. Combustion is the chemical reaction that occurs when the vaporized wax reacts with oxygen in the air.

The primary products of this combustion process are heat, light, water vapor, and carbon dioxide. The heat generated by the combustion keeps the process going by melting more wax and drawing it up the wick. The light produced by the flame is what we see as the glowing part of the candle, creating the cozy and inviting ambiance we associate with burning candles.

Byproducts of Combustion

While the main byproducts of burning candle wax are water vapor and carbon dioxide, there are also trace amounts of other substances produced, such as soot and small amounts of volatile organic compounds (VOCs). The amount of soot and VOCs can vary depending on the type of wax and wick used.

At Starling Petals, we prioritize using eco-friendly materials to minimize the production of harmful byproducts. Our soy wax and eco-friendly wicks are designed to burn cleanly, reducing the amount of soot and VOCs released into the air.

Wax Transformation

Evaporation and Combustion

The transformation of wax during candle burning is a fascinating process. When you light a candle, the wax near the wick melts and is drawn up the wick by capillary action. As the liquid wax moves closer to the flame, it reaches a high enough temperature to vaporize. This is where the real magic happens – the transformation from liquid wax to a gas.

Once the wax is vaporized, it mixes with oxygen in the air and undergoes combustion. This chemical reaction releases heat and light, which we see as the candle’s flame. The heat generated by the combustion process is what keeps the wax melting, continuing the cycle of vaporization and combustion. The primary byproducts of this reaction are water vapor and carbon dioxide, both of which are released into the air.

Byproducts of Combustion

Understanding the byproducts of candle combustion is key to comprehending where the wax goes when you burn a candle. The main byproducts are:

  1. Water Vapor: As the wax combusts, one of the products of this chemical reaction is water vapor. This is released into the air and is typically not visible.
  2. Carbon Dioxide: Another byproduct of the combustion process is carbon dioxide, a colorless and odorless gas that is also released into the atmosphere.

While these are the primary byproducts, it’s important to note that burning candles can also produce small amounts of soot and volatile organic compounds (VOCs). The amount of soot and VOCs produced can vary based on the type of wax, wick, and any added fragrances or dyes.

Why There’s Little to No Wax Left

Many people wonder why there’s often little to no wax left after burning a candle. The answer lies in the efficiency of the vaporization and combustion process. As the candle burns, the wax is continuously melted, drawn up the wick, vaporized, and combusted. This efficient cycle means that most of the wax is converted into water vapor and carbon dioxide, leaving behind little to no residue.

In some cases, you might notice a small amount of wax left in the container after the candle has burned down. This can be due to several factors, such as the wick not being able to draw up all the remaining wax or the candle being extinguished before all the wax is consumed.

Proper Candle Care for Efficient Burning

To ensure your candles burn efficiently and leave minimal residue, follow these simple candle care tips:

  1. Trim the Wick: Keep the wick trimmed to about 1/4 inch before each use. This helps maintain a steady flame and reduces the production of soot.
  2. Burn for an Even Pool: Allow the candle to burn long enough to melt the entire top layer of wax each time you light it. This prevents tunneling and ensures even burning.
  3. Avoid Drafts: Keep candles away from drafts, fans, and vents. Drafts can cause uneven burning and excessive flickering, which can lead to soot production.

Common Myths and Misconceptions

Wax Disappearance: Where Does the Wax Go?

A common misconception about burning candles is that the wax simply disappears. While it might seem like the wax vanishes into thin air, the reality is rooted in the science of combustion. As we've explained, the wax melts, vaporizes, and combusts, transforming into water vapor and carbon dioxide, which are invisible gases released into the air. Understanding this process dispels the myth of disappearing wax and highlights the efficiency of the burning process.

Visible Residue: What It Indicates

Sometimes, after burning a candle, you might notice a small amount of wax left at the bottom of the container. This residual wax can indicate a few different things:

  1. Incomplete Burn: If the candle was extinguished before all the wax was consumed, there might be some leftover wax. To prevent this, make sure to let your candle burn long enough to melt the entire top layer of wax each time you light it.

  2. Wick Issues: If the wick is not properly trimmed or is of poor quality, it may not draw up the wax efficiently, leading to leftover wax. Ensure your wick is trimmed to about 1/4 inch before each use.

  3. Container Shape: The shape of the candle container can also affect how evenly the wax melts and burns. Narrow containers or those with irregular shapes might cause tunneling or uneven burning, leaving wax residue.

We design our candles with optimal wick placement and high-quality soy wax to minimize residue and ensure a clean, efficient burn.

Soot and Smoke: Causes and Solutions

Another common misconception is that all candles produce significant amounts of soot and smoke. While it is true that some candles can produce soot, especially if they are not burned correctly, high-quality candles like those from Starling Petals are designed to minimize soot production. Here’s why soot might occur and how to prevent it:

  1. Overly Long Wick: If the wick is too long, it can cause the flame to flicker excessively, leading to soot production. Keep your wick trimmed to about 1/4 inch to maintain a steady flame.

  2. Drafts and Airflow: Burning a candle in a drafty area can cause it to burn unevenly and produce soot. Place your candle in a calm, stable environment for the best results.

  3. Impurities in Wax: Lower-quality candles may contain impurities that can contribute to soot. Starling Petals uses pure, eco-friendly soy wax to ensure a cleaner burn.
