Unfortunately it's not a 1 to 1 comparison between heaters. Wire gauge, build design, length, and the voltage controller being used (mine is 9-24V at 3A). I do have a heat gun I've been meaning to try out. I'll throw a piece on today and test at what temperature combustion begins.
I've actually been thinking about something. When I used to smoke herb, there were times in college we'd get some great nuggets but they had been over dried or cured for too long, so it was challenging to deal with and harsh to smoke. We'd throw an ounce in a glass ball jar and flick a few drops of water inside, cover it, and wait a few days - the water would rehydrate the buds evenly. Not sure why that happens (any Bill Nye's in here care to explain the science behind this process?
). In any event - could the same strategy be applied to oud? Obviously I'd take it slow and start with only a few grams in case the wood got ruined or moldy in some way, but I think the added moisture content would increase the wood's capacity for heat, and ultimately improve the odor as the resin could hit a higher temp without hitting a smoke point. Penny for your thoughts Edward?
