This guy I work with brought in a piece of Brazilian Redwood that he used to build an outdoor table. This piece is right at 8"x5.375"x1" but weighs right at 2lbs according to my postage scale at work...heaviest, hardest, most dense little piece of wood I've ever seen. And this piece has been kiln dried and stored indoors for over a year! I went to pick it up and dropped it because my brain was thinking it would be a lot lighter just looking at it .
I couldn't find a BTU chart referencing Brazilian Redwood but I'm guessing they dont burn too much wood for heat down in Brazil so I just did the math myself. Based on the dimensions above at 2lbs thats roughly 2lbs per 42 cubic inches (I subtracted the routed section out as well), which comes out to around 82lbs per cubic foot. Multiply that by 128 and you have 10496 lbs per cord!! Orange Osage comes out to 4845lbs per cord! Stuff is twice as heavy as Hedgewood, awesome! http://chimneysweeponline.com/howood.htm
EDIT: If I read that right, the ChimneySweep chart based the weight on 85 cu ft to account for air gaps in the stack. Based on that we're looking at 6970lbs per cord on the same chart. Still pretty dang good.
At any rate, its really expensive dimensional lumber so it would be crazy to burn and probably impossible to find for firewood here in the states, but one can dream...
Anyone else have crazy-exotic-wood-that-would-make-great-firewood stories?
6970lbs per cord!
Piece was routed...thats some tight grain:
