Gents,
A neighbor was kind enough to let me at a black walnut he cut down. I slabbed some chunks, sealed the ends, and stickered them in my basement in preparation for the next time I have some free time to turn. Unfortunately, within about two weeks some mold has developed (see pictures below). Looks like there's a bit on the sealed ends as well. I've heard about applying a borax/water solution. Any other ideas?

Thanks,
Moses
