Why won't the red clay I dug up separate after screeninig?

Question: I dug up some sticky red clay on my uncles farm, soaked it in water and ran it through a screen. I left it in a bucket so the clay would separate from the water but it still has not. It remains in slip form,I guess.

Answer: It depends on how thick the slip is, but if you leave it long enough it should settle out. It usually takes a few days. How long has it been and how thick is the slip? Can you include a picture?
