Hi Tony,
What an intriguing question. I'll consider this my lesson
for the day; hadn't known that the Chinese made molded
chopsticks (why not just coil 'em?).
Perhaps you can tell us a little more about the mold you're using.
Is it two pieces, split along the long axis, or one deep hole
in a block of plaster, or some other design?
I think there's potential for using compressed
air here, or some sort of sliding plunger to push things out.
Or perhaps you could line the mold cavity with a tube of thin paper?
Maybe just use paperclay slip?
Anyhow, with more info about the mold, I bet Clayart can do
some useful brainstorming with you.
Cheers,
Don Goodrich

Sounds fascinating. I too would love to hear more about molded chopsticks,
and look forward to reading the discussion. Don's idea of lining the mold sounds
a good suggestion. I have lined bisque molds with cheesecloth or tulle.
Thanks in advance.

If you put them in the mold and then let them stay
there until they shrink away from the surface, you can
invert the mold over two more chopsticks, leaving just
enough room for them to fall out of the mold onto the
table surface, eliminating the warpage.
Alternately, you can use a long wad of clay to grab
the whole chopstick at once and then leave it on that
until it sets up properly and then lift it off.
The reason chinese ceramic chopsticks would have been
molded would logically be to easily repeat intricate
carving or lettering on the upper half of the sticks.
