Black River Box
This is one of my first epoxy pieces, and one of the first woodworking items that I sold.
It is made entirely out of spalted oak. The center has a small black river on the top of the box. The box sides are made traditionally, with 45 degree miters that are reinforced with some keys.
I posted some details on the initial construction of this box, including how I mill the wood on my blog: Making a Black River Box
