1/5 Yesterday the bowl was coated with sanding sealer and left to dry. In this case, the wood is freshly cut so "dry" refers both to the sanding sealer and the wood itself. My hope was that the bowl would be thin enough to flex rather than crack as it dried. This was mostly true but several cracks are visible radiating from the center of a spot that had been a branch. If these do not sand out, I'll need to repair them. Fingers crossed at this point.
