I think the way it's split has a lot to do with how fast it dries. I got a load of slab wood a few weeks ago. I stacked part of it and then got busy and left the rest in the pile. Tonight I went out to stack some more. The stuff on the top of the pile is pretty dry. It surprised me so much that I compared some pieces laying on the ground covered up to what was on top. Not only did it feel drier, there was a noticable difference in weight. I wouldn't say its ready to burn after only a few weeks, but it's well on it's way. This stuff is 18" long 6-8" wide and 2-4" thick. It dries fast in the sun. The bark that fell off of some of the pieces when he dumped it has already curled up. Now if I could just get the other 4 cords delivered.
