I was able to use the break in the cob to hollow its core much more than I would have been able to, otherwise. The break was clean, so the crack line is narrow, now that it's glued back together.
Last night I saw that a loop of calcite overlay would hide the crack, and a second loop would make the first seem less odd. A third loop would be perfection, but come on, this was never meant to be the forever sculpture.
