Batt wash protects the surface of your kiln shelves from small deposits of glaze left on the base of pots by creating a barrier that absorbs the glaze. Batt wash comes as a white powder-mix with water to make a liquid the consistency of single cream and paint it onto the top surface of the kiln shelves only. Over time the batt wash will wear away -when this becomes obvious it is time to repaint.
