The Walnut bowl is the dark one. It measures 1.75 inches high and 3.25 inches in diameter. It was wet sanded with mineral oil and burnished with its own shavings.
Moving from that bowl, in a clockwise direction, There's a small Mulberry bowl with lots of knot and wavy grain, very wet, freshly cut wood. Just to see how it would turn out, I put some on the lathe. After shaping these into bowls I put them into a microwave oven for a minute a couple of times which took out quite a bit of moisture but they were still damp. By the next day they're drier but still wet but warped a fair amount, in each direction. Still they have a certain charm in their warped state. I expect them to warp further still.
