"Boomin" Burnishing Powder, named by my granddaugter Tiana. 

Large container yields approximately 95 uses.

Small container yields approximately 47 uses. Directions:  As this is a powder, wear a small particulate mask when handling the powder.  We also recommend you wear safety glasses.  Wash hands after use.  Keep out of reach of children and pets.  Store in a cool dry place. Use 1/2 teaspoon and distilled water in your tumbler, to clean your metal clay pieces.
