While cutting wood from log tops this fall, all Oak, we came across some very nice spalted pieces, that I saved from the furnace, it is in the shop drying out good before cutting up into blocks, I also cut a Black Jack Oak burl off of a tree to see what it looks like, it had a nice redish color and alot of figure, it is drying out also, but is cracking alot, so it may not work out at all. I will have to wait and see how it all looks when it dries and is cut. Has anyone ever used Black Jack? That is what it is called around here, not sure what the real name is, it is in the Oak family, and is very hard.
