How To Extract Clay From Soil
Pound it with a rock or hammer (use a mask) into a pulverized clay and put it in a bucket. Add an equal amount of water to the bucket. Let it stand at least overnight to absorb the water. Screen the clay using a screened box with 1/4 inch screening to filter out the larger chunks and debris.
