To ensure quality candle burning
Cylinder candles should burn for at least 3-4 hours per burning (4 to 5 hours is recommended for candles with a diameter of over 100 mm). In order for the sides of the cylinder candle to burn evenly, the burner should be located in the very center of the candle. A draft will prevent the candle from burning evenly, which can cause smoke and paraffin dripping.
To ensure the candle burns better, melted and excess wax or paraffin should be carefully poured off.
If the burner becomes too long and extends beyond the flame, it should be cut with scissors.
Candles burn out faster in warm rooms. Similarly, if a candle is burned close to a surface that reflects heat, or if the candle is placed at an angle or in a draft. A draft, for example, can cause a candle to smoke or burn with an excessively large flame.
Floating candles should not be immersed in cold water, as this will cause them to burn out more quickly. Room temperature or slightly warmer water will be best.
If you keep a candle in the freezer before burning it, it will burn more slowly and drip less. Adding a little salt to the melted paraffin or wax will also prolong the burning time of the candle and prevent dripping.
If the candle crackles, it may have been damp. You can dry it with a hairdryer, cut it with the wick with a sharp knife, and relight it.
