Avoid mixing quartz and agate. -Make sure rocks are of somewhat uniform size and add some rock chips to help circulate grit.-Make sure to thoroughly clean the rocks and barrel after each stage. Do not use harsh soap or cleanser on the barrel.-Add water just up to bottom level of the top layer of rocks. The goal is to get a thick slurry going.

How To Extract Clay From Soil | Survivopedia

Clay is a particular type of soft rock made up of minerals. It’s the leftover particles of rocks that have decomposed. Some clay stays where the original rock, such as feldspar, was. This is called primary clay. Secondary clay has traveled from its original home and likely picked up other minerals and rocks such as quartz, iron, or limestone.
