I tried to scorch a cherry bowl once several months back, the flame just made the wood crack - lots of checks as the heat drove out the moisture in the wood (not green, but probably still 12-15%), especially on the end grain. I muct have done it wrong. I was unhappy with my experiment.
Yours, however, looks to have worked out great. It's handsome as is, but it sparks me to thinking about doing wide rims at angles other than perpendicular to the rise or with convex or concave faces. Don't stop trying new things! There's always more wood.
