Dry, white glaze. I would call this a slip. At 1240c it is still dry =
like a clay surface. Very white. Can color with
stains and oxides. Can use over other glazes. Applied over a fired =
tile of Peter Pinnell's Seafoam. The=20
surface of the glaze moved and became very streaky. It ran over the =
bottom of the glaze border.
