Just so everyone isn’t surprised when they try to do this, if you don’t purify it further than this, you’re going to end up with a super silty clay that has very little plasticity. Trust me, I’ve spent days trying to figure out why my dirt isn’t like clay 😂 Look up the difference between sand, silt and clay and you’ll see its composition and size. Clay is super fine and although it’s almost everywhere, you likely have to dig at least 8 inches deep or find a water way or cut in the terrain to find it. Roll it into a coil, bend it around your finger, if it doesn’t break its very high clay content. If it does, you have your work cut out for you lol
