Nope.

The ****e size in partly-fired ceramics might be just about
right for the application, good as a depth-filter, cheap,
ready technology (you just need clay & fire), reusable
(just fire again to burn out the gunk) ...
It's a very good idea I suspect.
Can anyone help? Or suggest other methods?
I suspect what is being looked for is a way to form
the unfired clay in a semi-production method.
An alternative might be some fancy slip-casting too
but they would then have other needs (perhaps more
complicated).
