A patient of mine that cuts trees down for a living gave me some wood to cut up for handles. Got some really neat stuff too, including a piece of cherry that came from the Governors Mansion. But the question I have is that he also gave me some Persimmon. It was a fairly large piece and I am not sure what kind of Persimmon it is, but I cut it up on a band saw into 2.5"x8" pieces and stacked them up in an old grain bin that we have on our property. Earlier today I was going through them to take some of the wood with me on our move and noticed that there was several pieces that were stuck together. Now when cutting it up I did notice that there was a few small bore holes in some of the wood pieces but not allot and thought I could cut around them or get some of it stablized to fill them in. The wood has allot of cool grain patterns and color changes, light tan to brown. But when I pulled the pieces apart that were stuck together there was this white substance that was acting like glue. It is real white and light when you touch it. Kind of reminds me of a kind of styrofoam and will scrap of real easy with a knife. Is this something from some bugs that might still be in the wood or some kind of sap that is seeping out of the wood? I have never seen anything like it before. Any help or ideas would be greatly appreciated. Thanks. Sorry for the long post.
