Thoughts: Sooty Candles

soot.jpgLast week, I wrote about the tall pillar candle variety from Yankee Candle. While I liked that the design gave a great wax pool, I noticed the candle was pretty sooty and needed frequent trims. Now that I have burned through the entire candle, I noticed that sooty-factor only got worse.

For those of you who don’t know, I got my Ph.D. studying soot depositions into the ocean. Soot forms when the fuel to oxygen ratio is off – and is the result of incomplete combustion. In other words, soot in part will form in a candle if there is too much wick and too little oxygen.

I found myself having the trim the wick every 2 hours  – especially towards the end of the candle. But still, the outside was covered in that black soot. I am curious if this is the candle’s design, or if the wick in this one was faulty.

Either way – this candle smelled great, but was messy!

  1. I loved learning about soot causes, even though there doesn’t seem to be a great solution. When I got my furnace checked a few years ago, the hvac man mentioned he could tell I burned a lot of candles. We try to change the filter when needed and always trim wicks, but it makes me wonder if it’s worth it…
