Why Does Your Candle Create Soot? | Tips to Prevent Sooty Candles
Share
There’s something magical about lighting a candle and watching its soft flame flicker in the dim lighting. The aroma slowly fills the room, creating a peaceful, serene atmosphere. At Luminescent Candle Co., we know candles can elevate any space and mood, whether you're enjoying a moment of tranquillity, celebrating a special occasion, or adding ambiance to your home. However, even with the best quality candles, you might notice the formation of black soot around the jar or wick. While soot is a common occurrence with candles, it’s important to understand why it happens and how you can minimize it. In this blog, we'll explore the reasons candles produce soot and provide essential tips for proper candle care to keep your experience soot-free.
Why Do Candles Create Soot?
Candle soot is essentially the result of incomplete combustion, where not all of the candle wax burns cleanly. Soot is composed of fine black carbon particles that can accumulate around the wick, on candle jars, and sometimes in the air. While a small amount of soot is natural, excessive soot can be a problem. Here are some common factors that contribute to soot production:
1. Improper Wick Maintenance
The wick plays a critical role in how cleanly your candle burns. If the wick is too long, the flame becomes large and unstable, leading to incomplete combustion. This instability can cause the candle to flicker, which in turn produces more soot. A wick that is too thick can also create a larger flame, leading to a greater production of soot. Proper wick trimming is crucial to controlling the size of the flame and preventing excess soot.
2. Drafts and Air Flow
Candles are sensitive to airflow. When a candle burns in a room with frequent drafts or near fans, open windows, or HVAC vents, the flame may flicker constantly. This flickering leads to incomplete combustion and higher soot production. The dancing flame creates inconsistent heat, which causes the wax to burn unevenly. The uneven burning results in carbon particles being released into the air, forming soot. Ensuring your candle burns in a stable environment without drafts is essential for a soot-free burn.
3. Type of Wax
Different waxes burn differently. High-quality candles, like those at Luminescent Candle Co., are crafted from premium waxes such as soy, beeswax, or a high-grade paraffin blend, which are known for cleaner burning. However, lower-quality wax or cheap paraffin can contribute to soot production due to their impurities or additives. It's essential to choose candles made with high-quality ingredients to minimize soot.
4. Fragrance Oils and Colorants
While fragrance oils make candles smell amazing, certain types of oils, especially synthetic ones, may contribute to soot production if not formulated properly. Some candles with heavy dyes or colorants can also lead to more soot when burned. At Luminescent Candle Co., we take great care in balancing fragrance and colour to ensure a clean burn with minimal soot.
5. Burn Time
Candles are designed to burn for a certain amount of time per session. If you burn your candle for too long, especially over four hours, the wick may start to "mushroom" and form carbon build-up, which increases soot production. Long burning sessions can also cause the container to overheat, resulting in an uneven burn and excessive soot.
Proper Candle Care to Minimize Soot
With the right care, you can significantly reduce the amount of soot your candle produces, ensuring a longer-lasting and cleaner burn. Here are some important steps to follow:
1. Trim the Wick Before Each Use
Before lighting your candle, always trim the wick to about 1/4 inch. A properly trimmed wick ensures that the flame remains small, steady, and controlled. This minimizes soot production and allows the candle to burn evenly. You can use a wick trimmer or small scissors to do this.
By maintaining the wick, you prevent carbon build-up (often seen as black “mushrooming” at the top of the wick), which can cause excessive soot. If you notice the wick "mushrooming," blow out the candle, trim the wick, and relight it for a cleaner burn.
2. Avoid Drafts
Position your candles in areas free from drafts, fans, or open windows. A stable environment will prevent the flame from flickering and producing soot. If you notice your flame constantly moving, it’s a sign that there’s airflow affecting it. Moving the candle to a more stable spot will help maintain an even burn and minimize soot.
3. Use a Snuffer to Extinguish the Candle
Blowing out a candle can sometimes cause soot to be released as the wax is disturbed and airflow intensifies around the wick. Instead, use a candle snuffer or gently dip the wick into the molten wax with a wick dipper and then straighten it back up. This method reduces soot and prevents the wick from smoking after being extinguished.
4. Burn Candles in Proper Time Frames
Avoid burning your candle for longer than 3-4 hours at a time. Extended burn times can cause the container to overheat, which not only increases the likelihood of soot but can also be a fire hazard. After 3-4 hours, allow the candle to cool and solidify before relighting.
On the other hand, you should also avoid burning candles for too short a time, as this can cause tunnelling, where only the centre of the candle burns down, leaving a lot of unused wax on the sides of the jar. Ideally, let your candle burn long enough for the entire top layer of wax to melt evenly.
5. Choose High-Quality Candles
Opting for high-quality, well-crafted candles makes a world of difference when it comes to soot. At Luminescent Candle Co., we use premium soy and coconut waxe, natural cotton wicks, and carefully formulated fragrance oils that are designed to burn cleanly allowing minimal soot occurance. Choosing candles made with top-notch ingredients will not only reduce soot but also enhance the overall burn experience.
6. Keep Your Candle Container Clean
If you notice soot forming around the rim of your candle jar, gently clean it off with a damp cloth when the candle is cool. Removing soot regularly prevents it from affecting the quality of your burn. A clean jar allows the candlelight to shine brighter and ensures a better appearance.
7. Store Candles Properly
Store your candles in a cool, dry place, away from direct sunlight or heat. Extreme heat can cause the wax to melt or warp, leading to uneven burns. Keeping your candles in optimal conditions ensures that they burn cleanly and reduce the chance of soot.
While it’s natural for candles to produce some soot, especially as they near the end of their burn time, following proper care guidelines will ensure a cleaner, longer-lasting burn. At Luminescent Candle Co., we are committed to providing high-quality candles that bring warmth, fragrance, and ambiance to your home. With a little maintenance and attention, you can enjoy your candles soot-free, allowing their beauty and scent to shine through every time.
So next time you light your favourite candle, remember: a little care goes a long way in keeping your candles burning cleanly and beautifully!
