I just counted up the bodies that Tuckers sells - about 40 - 20 of which I
formulated from scratch.
I'm not boasting about this - in fact when I started doing it I was simply
not aware of just how difficult it would be.
In the old days before my dilatometer and calculation software - it was a
lot of trial and error. What I learned from testing and calculating made
the process quite simple - compared to doing it without calculating
software.
Many would be surprised just how easy it is.

It must be quite a burden for you to wear the mantle of such greatness--- by
the way-- How much of those bodies does Tuckers sell every month??

Craig Edwards turned me on to testing B-clay for Continental.
Putting it in his kiln and the NCC cantenary.
I also saw the last of the Minnesota Indigenous that I had
testing for Minnesota clay, from about 15 years ago. I loved it.
They used an unrefined iron bearing kaolin. I hear it is primarily
used in industy. But they got complaints from tableware makers, from
lime pop-outs, which made no matter in woodfiring. Actually, it
would be easy to remove by slaking and screening (that is how they do
indigenous clay in Japan.) Had so much iron they only used a % in the
clay body.
Boxes of indigenous are rock hard now. Will bust them up and
reconstitute them. Only use the last for teabowls and guinomi. I
have clay dug up when they were putting sewer pipe in front of
Hamada's pottery. Saving that for special stuff like stamps and
guinomi. Have been "annointing" my other clay with just a pinch from
the Hamada bag. Homeopathy amounts of Hamada's in my clay. ;^)
