I'm new to this site but I was wondering if anybody could identify the layering of this soil please and any other information would be greatly appreciated.
I'm in NC and I believe they call this Marlboro-Cecil mix. I've been screening some of it to see what's in it. I'm running 20, 80, 200, 400 mesh after 400 I run the material through a 3 micron filter bag then through another 1 micron filter bag. What passes through the 1 micron I keep for ultra pure clay. What passes through the 3 micron is then remixed with the 80 mesh screenings, flax fibers and titanium powder, to make custom mud bricks "not fired"
