Jed, it's the oddest thing. Nothing has separated out! It's consistent top to bottom....??!
Bill did add sand from our creek to a small batch of clay but the jury is still out on that attempt to strengthen the clay. It seems that after the small pot that he made with the altered clay began to dry, it was stronger than a pot made with that clay before the addition, but while working it, it still felt hinky. I dunno....... Jayne
