When scented candles emit black smoke after being lit, the reasons can be summarized as follows:
- Wax Composition: Using paraffin wax as the primary ingredient in candles is more likely to produce black smoke. It is recommended to opt for candles with a base of plant wax, beeswax, or coconut wax.
- Wick: Cotton wicks are less prone to generating black smoke, but they should be regularly trimmed to maintain an appropriate length. An overly long wick can lead to excessive burning, increasing the likelihood of black smoke.
- Extinguishing Method: Use professional candle snuffers or wick trimmers to extinguish the candle or directly cover it with a heat-resistant lid instead of blowing it out. This prevents the creation of black smoke and the risk of wax splattering, while enhancing safety.
- Placement: Avoid placing lit candles in areas with air turbulence or strong drafts, ensuring thorough combustion and reducing the chances of black smoke.
By following these guidelines, you can enjoy a more pleasant and safe experience with scented candles.
