Tae,

Throwing off the hump is the most efficient way to go. As you get good at it, you will only have to trim pretty much around the foot ring as you can nearly throw the work complete off the hump.

hi everyone


just wanted to hear your opinion. i learned pottery by throwing off the
hump. however, if your are trying to make the same shape in sorta mass
production mode, is it better to keep throwing off the hump? or should i
just use molds?

Depends upon the form. Tell us what you are trying to make.

Irregular or complicated shapes are sometimes easier making
with a mold. I just came back from my second viewing of the Kutani
show in Kasama. Also watched a movie at the museum about Arita
porcelain. Many Kutani and Arita shapes were made in molds and
sometimes things were thrown and then shaped with a mold, or a design
was pressed into the shape after throwing.

Tae,, here are a few questions to consider before making your decision.
How many of the same piece do ya wanna make. Do they need to be exact
duplicates? Do ya wanna get into the slip casting biz? How fast are you?
WOuld you rather do the production thing off the hump or from a whole
bunch of molds. How quickly do you need to be up and running? You'll
need to consider the time factor and learning curve if you go the route
of mold making and slip casting.
Hope this helps

If you are fast and it is a simple form, I would guess that
throwing is faster.

If press molded things require multiple slabs to make,
they can take longer to make than throwing and trimming the same sized
dish. I sat next to a Shokunin/craftsman that made square Kokusara
in a mold, and they took much longer to make than simply throwing a
dish the same size.

Maybe you should visit some production potteries and watch the
different processes?
