After several weeks, with rainy every day moisture, two bowls (unpainted) are firewood the other four have minimal checking. Those are the two with Anchorseal applied. I believe they have not reached ambient moisture or equilibrium moisture content (EMC). The 100 watt bulb was to hot for the 30 gallon can size. They just dried too fast. Going to try boiling the next ones for one hour and drying in a brown paper bag for three weeks. This is a method off the internet. It recommends this with success. I am in a hurry because I have little storage for blanks or green bowls. Roger.l
