Sifting sand. I was in the process of working on my final project in my glass class, which would be a mixed media sculpture. One part of it would be a cast glass shape. A sand mold is made by sifting sand into a large wood box, so that it's loosely piled in the box. Then the object that will be used to make the mold is pressed firmly into the sand, hard packing it around the original piece. After removing the original, molten glass is poured into the vacated space, taking the shape of the original object.
