The obvious question is: what do you plan on using the clay for? If you are making something, like a vase or lamp base, you can tolerate having additives in the clay to make it work better for that, but if you want to make fertilizer balls you can't tolerate those additives.

Where I live and have lived, there is a lot of clay available by digging down a foot or so almost anywhere. That is where I have obtained clay. And, now I use silt from the American River, which is virtually in my back yard, and which is largely coarse clay. That is a more fertile clay, plus it still has the high CEC of clay.
