Laguna clay states: This is a blend of minerals that closely simulates Barnard (Blackbird) Clay, a widely used clay that contains iron and manganese. This material was developed to mimic the effects of Barnard clay when used as a wash or when used in clay body formulations. Though it can be added to glazes as a substitute material, its effects may vary from the original.
