A few of my coworkers and I spoke today about candle scents that are, possibly, too strange to exist, but whose existence would make us happy. I should like to know whether they do exist, and if we may buy them.
Sulfur (blown-out match)
Recently blown-out candle
Gasoline
Dust (moldy basement)
Heh.

They used to burn sulfer to purify the air so people didn’t catch the plague.
Wag- It was likely to have kept desease carrying insects away.
Sulfur was used to cover the decay smell also.
I’ve run into black candles scented as leather and as musk.
Wag- They must be for the basement bondage room.

You can get a candle that smells like dirt
I have a couple of redneck candles I received as gag gifts, one smells like Brut and the other like beer.
