First suggestion, move the question about drying bowl blanks to either casual conversation, or other things we make. Casting and stabilization might not be the best place. Mountains of info on the web, guys that rough turn and soak in alcohol, rough turn and soak in dish washing soap, rough turn and air dry, rough turn and kiln dry, turn to completion while green, throw green blanks in the freezer............you get the message. A simple Google search will give you about 6 months or reading.
