Ball clay is the term most people use. I would not trust Wikipedia, as
anyone can fiddle with the definitions.

Wikipedia seems to have a good definition of ball clay with some sources to
back it up. It is somewhat geographically specific, so having been recently
corrected myself, white pipe clay seems like a safe bet.

Subject: Ball clay, white clay, or kaolin?
Hi Guys,
What is the current thinking on the use of ball clay vs. kaolin vs.
some other descriptor for describing white clay pipe raw material.
Many years ago, the use of "kaolin" was a sure sign that the speaker
"really" didn't know what he was talking about ... and "ball clay"
was the preferred term. But I am pretty sure that I am still seeing
"kaolin" used pretty regularly ...
Would welcome any comments or references ...
Thanks.
Mark
