Kaolin was first mined in Colonial days in Georgia and then shipped to England. Georgia was the source of clay for famous Wedgwood Pottery and this resulted in the end of mining in Georgia for over a century. By 1876, mining here was resumed and today it continues as the major mineral production of the state by producing 72% of the total kaolin.
