Good little pot, I like the shape. Sounds like you were cooking it, not drying it! But it seems to have done the job.
I just turned a cherry vase from a log that was felled only a week ago. I didn't dry it nor did I part turn it but took it straight down to around 3 or 4 mm all over and so far it's survived. I'm leaving it in the workshop for a while to let fuully dry before taking indoors though. I was careful to make the base concave so it won't wobble as it inevitably distorts a bit in the middle.
