Candle making is not just a simple process of melting wax and adding fragrance. There is actually a science behind it, which plays a crucial role in understanding why candles may produce black smoke. To better comprehend this phenomenon, let’s delve into the scientific aspects of candle making.

The candle making process involves three main components: the wick, the wax, and any additives or fragrance oils. The wick serves as a fuel delivery system, drawing liquid wax to its tip where it undergoes combustion. The wax serves as the fuel source, providing the necessary energy for the flame to light up. Additives or fragrance oils can enhance the aesthetic appeal and scent of the candle.

During combustion, an intricate chemical reaction occurs between the wick and the flame that releases heat and light. This reaction transforms the solid wax into liquid fuel through capillary action within the wick fibers. As this liquid fuel reaches the flame, it vaporizes and undergoes further reactions with oxygen from the air, resulting in carbon dioxide and water vapor.

However, when candles produce black smoke, there is a disruption in this delicate combustion process. The black smoke consists of tiny soot particles released from incomplete combustion due to insufficient oxygen supply. Black smoke can also occur when low-quality or improperly processed wax is used, containing impurities that contribute to soot production.
