Today, Levi and I dug up some of the clay and brought it back to give it a try on the wheel and in our kilns. We both grabbed a handful of some of the softer clay and wet it down and smacked it together a few times, then threw a piece on the wheel. I think it shows some promise. It's very similar to what I've dug up on another part of the property, but it seems to have some bluish clay in it as well.
We're both hoping that if we keep digging, we'll hit a vein of blue clay. We'll see.
