Turning Acid Mine Drainage Pollution Into Pottery
The brilliant rust orange iron oxide that’s pulled out of waterways polluted with acid mine drainage is finding its way into the hands of artists and craftsmen. The dried and powdered material is being used to color T-shirts, wood stain, concrete, and even the “burnt sienna” shade of Crayola crayons. Now a nonprofit is helping turn creek contaminants into pottery glaze.

"And I said, 'You can use this?' And she said 'Yes.' She made a few pieces. Now we have seven potters that contribute—ceramic artists, I guess you would say. And all the money from the sale of the material and the pottery goes to help watershed groups."
