Creosote on the glass

[Easy Livin’ 3000]

It is interesting and informative to watch creosote condensation on the glass, and how the airwash cleans it off. Tells a lot about the condition of the wood, and what would be accumulating on a cold chimney or chimney liner. I seem to get a lot more from oak than other wood. Probably means that it could be drier, and that it has more calories in it than my other woods.

I've made that observation as well. I'm currently burning poplar almost exclusively but I see it when burning elm and boxelder (yuck) too. I'm not finding creosote when cleaning the exhaust system however; only a moderate amount of fluffy black/brown stuff. The condensation on my glass burns off from top to bottom when running secondary air only. The glass cleans up rapidly if I crack the primary intake a smidge.
