One question, since iam bidding on your auction.
Is it slightly broken? Looks like it on the pics. Under the 2015.
It's the grain, In order to cure Purpleheart against oxidation (it ensures this hunk of wood will still look exactly the same in 10,000 years) you have to bake it in the oven at 450 degrees F for one hour. It causes the entire piece to expand and widens the grain, some of the highly resinous grain tears. As it cools the grain resumes its normal size the highly resinous grain fills back in with the natural resin in the wood.
Forgive the crappy cell phone picture but you can see that the tear which looked big in the original photos is now under the size of a strand of hair, and over the next week or two as the wood settles you will not even see it. As you can also see, the wood is starting to age and it is starting to turn its crown royal purple color already too. Much more beautiful than the original photos when it was fresh out of the oven.
Someone who was in my gallery today offered me $2,000usd for Mazuma and they dont even know what Bitcoin is. Sadly i had to tell them it was not for sale in the gallery and if they wanted to buy it they would have to bid on the auction on Bitcointalk.org. They looked at me like i was insane (which is fine, i'm an artist and were all a little crazy and eccentric) and bought something else
