This one is from spalted Hackberry that I almost let go too long. It was a bit punky in areas and had some bug frass inside, too.
It's 7 1/2" tall x 5 1/2" wide finished with Minwax Wood Hardener and sanded to 12000 MM. The mouth started out 2" i.d. but one last touchup with that Sorby Hollowmaster forced me to widen it a bit.
