As a combustion expert with a background in chemistry and environmental science, I've spent considerable time studying the byproducts of various combustion processes, including those from candles. When it comes to the production of black soot from candles, it's a complex subject that involves a variety of factors such as the type of wax used, the wick, the presence of additives, and the conditions under which the candle is burned.
Candle flames, like wood burning fireplaces, can indeed produce soot as a result of incomplete combustion. This occurs when there is insufficient oxygen to fully oxidize the fuel, in this case, the wax. The process of incomplete combustion leads to the formation of carbon particles, which are visible as black soot.
However, it's important to clarify that not all soot is created equal. The soot produced from candles is not the same as the toxic black petrocarbon soot found in petroleum-based candles. The latter is known to contain a variety of harmful chemicals and pollutants, whereas the soot from a well-maintained candle is generally less harmful, though it can still be undesirable.
To minimize soot production, there are several steps one can take:
1. Choose the Right Wax: Some waxes, such as soy or beeswax, burn cleaner than paraffin, which is a petroleum byproduct. Soy and beeswax candles tend to produce less soot.
2. Use a Proper Wick: The type of wick can significantly affect combustion. Cotton wicks are preferred for cleaner burning, whereas wicks made from other materials can produce more soot.
3. Proper Wick Trimming: Keeping the wick trimmed to about 1/4 inch can help ensure a cleaner burn and reduce soot production.
4. Adequate Ventilation: Ensuring that the area where the candle is burning has good airflow can help provide the necessary oxygen for complete combustion.
5. Burn at the Right Temperature: Burning candles at a cooler temperature can also reduce soot production. This can often be controlled by adjusting the size of the flame.
6. Quality Additives: Some candles contain additives that help to reduce soot. Look for candles that are advertised as producing less soot or are made with natural materials.
7.
Proper Candle Care: Keeping the candle free of debris and ensuring that it is stored correctly can also contribute to a cleaner burn.
8.
Burn Time: Not over-burning the candle can also help. It's best to let the candle burn until the wax pool reaches the edges of the container, but not so long that the flame gets too high.
It's also worth noting that even with these precautions, some amount of soot may still be produced. This is a natural part of the combustion process. However, by taking these steps, one can significantly reduce the amount of soot and ensure a cleaner, more pleasant burning experience.

Candle Flames, wood burning fire places, all have incomplete combustion which produce soot, but the good news is it is not the toxic black petro carbon soot that you find in petroleum based candles. There are some things you can do to radically limit the amount of soot produced from the candle flame itself.
