Also known as Kiln Wash or Shelf Primer.
How to apply:
Mix same weight in water to the powder, apply to your kiln shelf with a Haik Brush, let dry then add a second coat with the brush strokes at right angles to the first coat. Use only on the upper most side of the shelf.
It is advisable to put your shelf through a dry firing (a bisque will do) before taking it to glaze temperatures.
This batt wash will last for several firings or until there is a glaze accident, and areas can be touched up without re-washing the entire shelf if needed.
