Cob: RE: acquiring clay-types

[Patrick Newberry]

We have both here in middle Georgia, or at least near me. The red
georgia clay here has sand in it. 
But other parts of Georgia, particularly north Georgia, has much less
sand than here. 

Our Kaolin is very white, and very fine, and very sticky, not much sand
in it. 

The sand pits throw the chuncks of Kaolin in piles and leave it as a
waste product. I have at least
three or four sand pites within 10 miles of my house.

Georgia Clay is always red I thought, and Kaoilin is usually pale grey
to whitish.

I am betting the Georgia clay has sand in it, and is very sticky, right
Pat? more like a Gumbo clay ( gumbotil is the tech name)

here is the clay range senario
Most dense and
sticky..................................................finest particle
clay
Gumbo-(Montmorillionite) (water loving)......................Kaolin
(least H20 affected)

so buying potter's clay- Kaolin is good becuase it shrinks and swells
the least, and  not much is needfor those sandy Floridians.

Kaolin is mined, sifted and bagged..very easy to get and use.
