Here is the sand. What's it for on this piece? [id=404765295]

Thanks to Rick S., my question was answered in moments: "The sand is so the glaze on the sanded side of the insulator doesn't stick to the floor of the kiln when the insulator is fired. It is sometimes called a sand rest as opposed to other unglazed surfaces that you find on porcelain insulators."
