Finding and Processing Your Own Natural Clay : 5

Processing my clay dry is pretty much the only way I refine my clay. I like this method because I am very impatient, and waiting for your clay to settle, than letting the water evaporate is very difficult for me. This way is faster and more hands-on. It also adds that "primitive feel" to the work. But the bad news is that it isn't nearly as good at getting all of the foreign material out as
