Yes, Russ, that is exactly what someone needs to do. Here is the latest information on the clay bath. Apparently, there are little black specks of something in the clay. When you mix fresh clay with water and take a close look at it, there are tiny black specks in it, like someone sprinkled black pepper in it. So now we are wondering " What turned the clay black? Mercury, or those tiny black specks in the clay?" We will continue to investigate this matter and give our report.
