Brad,
B mix is a porcelainous stoneware--more on the stoneware side I suppose. It is not a porcelain by definition of what's in it:
Old Hickory #5 50
EPK Kaolin 20
PV Clay 28
Talc 2
S cracking has to do with compression in my opinion as witnessed in throwing off the hump or other method and not compressing the bottom well enough.

Lili's discussion of clay bodies and Lynn Goodman's question about sagging
porcelain platters have brought to mind questions I have on B-Mix. I
understand B-mix is a porcelainious clay. But how similar is it to porcelain? Is
B-Mix a hgigh-talc clay? Mel recently wrote that high-talc clays have a strong
tendency to S-crack. Is porcelain a high-talc clay? If so, does it also
have the tendency to S-crack? Thanks to anyone who can shed some light on
all this?
