looking for a good low-fire porcelain

Readers,
I am searching for a good low-fired porcelain body. Something with little
shrinkage, elastic, and translucent and something nice to work with for
cone 6 or so work. Preferably something I can mix up myself in the studio
here although I am not apposed to a premixed clay. Sometimes shipping
distance makes it rather non conducive to obtain ..freight bills etc. I
have been working with cone 9 porcelains for some time but need to expand
my work to a lower vitrification for the lower glazes. Any suggestion of a
good one to try?

Thanks in advance.

6......

It is going to shrink, it will not be elastic, it can be translucent.

Try

Nepheline synite (or g200 feldspar or kona f4) 32-50%
grolleg kaolin 25 to ?%
silica 25%
just say no to ball clay
and some v-gum or macaloid for plasticity.

I haven't got a recipe for you, but I highly recommend Standard #365.
Not as cream cheese-y as some of the others I've tried (and I've tried
them all, I think) but lovely and translucent.

If translucency is not an issue, try Standard #551. Same whiteness &
brightness. Nice to touch bare when fired, but not translucent.
Throws like stoneware!

Good luck.....Lo
