I started using denatured alcohol to help speed up my bowl drying back at the beginning of the summer. I have dried approx. 50 bowls from 8" to 12" of maple and black cherry and have had probably 95% or better success rate. They are from 8-10% moisture in about 6 weeks. I turned about 20 walnut bowls about 6 weeks ago and unwrapped them tonight and about 15 of them had huge cracks in them. My process: rough out to about 1", soak for 4 hrs, flash dry, and wrap in 2 layers of newspaper and place on the shelf. I was wondering if the alcohol just " wore out"? I started with 5 gallons and over the course of the summer probably added another 4 gallons due to loss or evaporation. What do you guys think? Thanks, Michael
