The dehumidifying effect of candles cannot be ignored. The scented, jelly, floating， tea waxes, and meal candles used in life can all be used now. After the candle is ignited, there is a specific function of dehumidification, and the principle is that burning causes some moisture to condense, thereby reducing indoor humidity.
Before each ignition, the wick is trimmed to 0.5-0.7 cm. It is not easy to produce black smoke when burning. Could you put a small amount of water in the cup before placing the candle into the candle cup or candlestick? This will make it easier to change the candle and avoid damaging the candlestick. The scented candle can use the combustion principle to burn the odor first and then spread the aromatic molecules into the air. Still, the scented candle is unsuitable for food and beverage use. In addition, it is not appropriate to ignite different scented candles simultaneously in the same space; after every 2-3 hours of combustion, it is necessary to stop for some time to prevent excessive oxygen consumption in the room.
