Junk Wood

Walking on my property a few years ago I saw a chunk of wood on the ground. Picket it up, it looked like any old chunk of rotten wood.  Took it home.  Put in in a container, and poured aluminite over it and let it sit for a couple weeks.  No pressure pot, nothing special done to it.   Took it out and decided to turn it, just to see.   What a pleasant surprise.  This is what I ended up with.  It is a little over 3" tall and 3" diameter.  I have no idea what the wood it, maybe if was a knot out of some tree.  I know mulberry can be very colorful, we have lots of mulberry trees around.  Unfortunately it has since turned brown still pretty. but not as flashy.
