2 years ago, I cut a 3.5' diameter oak that had been dead for, well, since I had moved here so at least 3 years. It sat in rounds cut 16-20" lengths for a year, last year around this time, I split it. It's all stacked for use either late this burn season or next year. BUT, a couple pieces were just too long so I cut an edge off thinking I might use some nice 3' diameter 1" thick rounds for, well, whatever. Anyhow, a couple of those 1" thick slab broke in 2, so I had like half circles 1" thick. After I cleaned the flue last May, I stage a fire, and I placed 2 of these 1" thick half rounds in along with some ash,maple red oak, because, well, they just seemed to fit nice and make a nice aesthetic look for the whole summer with a staged set of logs of various sizes/shapes in there...etc. Anyhow, it's supposed to be 21 here tonight, and only a high of 35 today, so I decide I light it off early this morning, first fire this year. Wood sitting in that stove all summer long has a slight draft running through there, the meter says 8% on the couple of ash and red oak splits I quickly tested. Since I didn't buy any firestarters yet (don't worry, ordering super cedars later tonight), I put some small fat wood and shredded paper and she lit off. It didn't take off like I expected at 8% moisture, so I crack the door slightly and I hear a huge hiss, I'm like, WTF is that, I look in and see water bubbling out from those 1" thick half rounds. It's super dense white oak from the base of the 125 year tree that it was, but still dead for years, stacked in full rounds for 2, cut off for the last year at 1" thick, place in a stove for the whole summer I figured that wood would be about as dry as any wood could ever, get. Wrong. That white oak simply takes time. Water, bubbling out after all that?! The rest of the 2 year old red oak lit off like kindling and dryed out the white oak in short order, and the stack was running 600 in no time, but still, visible water, after all that time?! That's some dense wood right there!
