Again, I believe this to be some type of plum, but not sure. 4 1/2" diameter. Microwaved 4 times for 2mins at 20% power(Seems to be the right amount for this wood). Sanded to 600g and finished with Briwax Friction Polish(don't get this stuff on your fingers it's a pain to get off..lol).
Looks like you have the procedure down for plum. Very nice. This one does not have the character in the wood that the other one has, but still a nice piece. 8)
