Just in case you can't tell, that is a glass insulator in wood. My friend T.J. heats with wood, and last year while he was cutting wood, and splitting it, he found this in one of the logs. He gave it to me as I thought that it was pretty cool. He told me he wouldn't ever burn it, but he didn't know what to do with it and it was just sitting in his wood shed. I think that I'm going to see if I can take off a little more wood to expose it more, then put it on the porch, or in the flower bed. I just wonder how the glass insulator got stuck or so close to the tree that the tree grew around it. This is a good size chuck of wood.
