Potter's Comments: This was my first doughnut vase! I am quiet happy I was able to do it in only two attempts --- even if it isn't a perfect cylinder. The other thing I am happy about is the glaze --- turquoise blue and black painted in various widths and thicknesses over a thick 5-second dip in white. The first time I tried that all the colors ran together and I got a glossy black mess that stuck to the shelf.
The vase was thrown first, and then a hole gouged in the side and the spout added at the leatherhard stage. The foot was added at the same stage - I used a different technique than the traditional Japanese one, however.
I threw the doughnut body by pressing down and out from the center until I had a ring of clay with literally no clay at the center of the bat at all, then pressed inwards at the bottom of the ring until I had a sort of low narrow base on which the ring of clay sat.
After that, I pressed down at the middle of the ring's rim and simply threw a double-walled bowl, but kept the sides curving towards each other - i.e. the inner wall curved out towards the outer wall and vice versa - until the walls touched. Then I gently joined the walls by pressing them together and smoothing the join as best I could, while still on a slowly revolving wheel.
I left it on the bat for 24 hours to firm up (over here in Malaysia, our weather has been very hot and quite dry since last year so it took just 24 hours for the clay get a little stiffer than leather hard). I also threw the spout, which I cut off without its base (like a bottomless cup).
When the circular tube was leather hard, I removed it from the bat and trimmed the lower edge until it was smooth and round like a proper doughnut. I added a foot for the base by attaching a coil of clay and shaping it until it was firm and allowed the vase to stand steadily before gouging a hole at the opposite end (the top). The spout was added on top of that hole and then the whole thing was smoothed all over with an old teaspoon.
The traditional foot which my Japanese teachers usually add is two half hollow cones (like ice cream cones cut top to bottom) at each side of the ring but I thought it looked a little too fragile so I changed it to a more Chinese looking foot ring instead.
