Great PDF for wood weight

[joecool85]

The State of Maine has provided a great PDF showing seasoned and unseasoned weight for cords of different species of wood. Check it out: http://www.maine.gov/doc/initiatives/wood_to_energy/documents/greenandseasonedfirewoodchart2.pdf

It's very interesting. I've seen plenty of charts for seasoned wood, but for fresh cut I hadn't found anything until this.

Love that Black Locust

interesting how much water weight red oak has. that just further validates the fact that it takes so long to season

Not so much the initial water content as much as the cell structure of the wood grain that requires longer seasoning.

Good reference.
I see at the bottom right, Seasoned wood is 36 - 20 % & dry is less than 20%
Seasoned is different than dry .
Good thing to know when buying wood.

Here's one that the Northeastern Loggers' Association puts out in its booklet, "Log Rules & Other Useful Information." This is for lumber and cordwood, but you can easily see the relationship between dry and green wood, and in the process, figure out which species are likely to yield the best firewood.

It's true. Willow has the most water content on there but still seasons in one summer. I know, because I burn a good deal of it.

Which is why I like seasoning my own firewood. To me, seasoned is dry, not just dumped outside for the rainy season

Very cool.Seeing the BTU's wasted burning wet might convert some people.

Interesting tp compare the two sets of charts. The second shows the same weight loss for locust, hickory and sugar maple, going from green to 20% moisture. Quite a difference one set of charts to the next. Also, the second set of charts lists different weights per cord in each chart....And, in support of the old saw about ash being good to burn wet or dry, the weight of dry vs wet ash changes about 600 pounds per cord versus the 1700 pounds per cord for hickory, locust and maple, giving ash about 31 % moisture content green, while the other three are nearer 43 %..
One of the charts too states that it bases a cord on 80 solid cubic feet of wood. I had always heard that 86 cu feet was the minimal acceptable for a cord....

The incongruities are interesting. I appreciate charts like these, so thanks for posting. The more I can learn, the better. And it's really nice to know about what a cu ft of a dry piece if a particular species should weigh, though I'm sure that varies tremendously with how quickly the tree has increased in girth.
