Is it necessary to ever recoat the kiln bottom with kiln wash

Updated on Jan 24, 2025

The kiln wash adheres to the firebricks better than it does to shelves because the firebricks are porous. Therefore, it is rarely necessary to apply more kiln wash after the first application when the kiln is new. Apply more kiln wash to bare areas after removing glass or glaze that has dripped onto the firebrick bottom.
