FIRING SAND - 2 LBS.

Fine sand for porcelain high firing. Normally used as a fine dusting of sand on the kiln shelf, so that porcelain pieces can shrink without warping during the high-fire. Re-usable, no pre-firing necessary. Warning: Wear protective mask when using. Each jar contains 2 pounds (0.9 kg) of firing sand.
