Failure/Cracking rate for twice turned bowls?
Over my Christmas vacation I rough turned a bunch of bowls and then put them in brown paper for final drying and a few of them have already got cracks all the way through. Someone suggested instead of the brown paper painting the entire bowl with Anchorseal and turning the walls a bit thinner than I had. I'm disappointed, but not totally crushed.
However I'd like to make sure my expectations are realistic, so assuming I start with logs which are green enough to through water drops while rough turning and then coat them with Anchorseal, what would you use as a percentage for how many bowls you'd expect to survive? Is close to 100% achievable or will there always be a fair amount of bowls which don't make it? Are the bowls which develop a through crack automatically firewood or can they still be safely turned and either repaired or just labeled art (don't hold soup)?
It's a snow day here in CT today so I've got the itch to turn some bowls.
