Cob: RE: acquiring clay-types

[Charmaine R Taylor]

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.
