Knowledge about candle

New knowledge about candles. We love candles, and we don't have to avoid them if we think about it when we use them. New analysis shows that if candles burn at optimal combustion conditions, the harmful particles are greatly reduced. Candles emit fine particles that can be harmful to health, but new experiments also show that if the candles are protected from drafts, the carbon black level, which is an indicator of soot, is very low. The Danish Environmental Protection Agency has supported the project "Environmentally friendly candles with reduced particle emissions" with MUDP funds in 2016-2018. The study confirms that candles are a significant source of fine particles in the indoor climate. The study also shows that the emission from candles with optimal combustion primarily consists of water-soluble salts (used to impregnate the wick) and has a low level of carbon black: This study shows that stable burning is an important parameter in the development of more environmentally/health-friendly candles, says Magnus Løfstedt, Head of Department at the Danish Environmental Protection Agency and continues: - However, it is also important to emphasize that the project does not include studies of candles that are in a row, flicker or soot. Previous studies have shown that they have higher emissions of, among other things, carbon black. The Danish Environmental Protection Agency recommends that consumers choose high-quality candles, and they should cut the wick if it becomes too long. The candles should be protected from air currents that cause them to flicker, and you should also ensure that they burn with a calm flame and without sooting.
