MAMMOTH IVORY POWDER dust collected from our band saws and belt sanders, is approximately 99% genuine mammoth ivory (no walrus in this batch) but will include some other dusts. The color is light tan/ivory colored (not gray), it is like flour, we have triple sifted it through fine mesh screen to remove chips and lint. Make your own ivory black, add to casting epoxy and make reconstituted mammoth ivory (may need to add white tinting agent depending on the resin),or how about as a prehistoric calcium supplement for plants.   A one pound bag is shown in photograph and is 4 cups.  We only have 4 pounds left and no more. 9/5/24
