I have heard tell of a turner that puts his newly turned bowls on the bottom shelf and each week moves them up a shelf. When they get to the top shelf they are ready to finish turn. No, I did not hear how many shelves were involved. Well, I gave up on the plastic bag thing, I couldn't remember to do it every day. However the rough turned bowls are dried, a few are always lost to splitting.
Dry wood is harder wood.
It has become denser with the lack of moisture, the fibers moving closer together, making it more difficult to turn. But it is stable. What you turn is what you get. Very seldom will a dry wood bowl warp or crack. Of course, there may be checks already in the wood that turning brings out.
