The dramatic "Northern Night" surface is achieved by combining two quite different glazes.
The darker portion is an “oil spot” glaze — which when fired quickly to a high heat, causes iron components to burst to the surface and leave glistening or sparkling highlights. Layered on this is the blue crystalline glaze, which creates a luminescent Northern Lights effect when it melds in the kiln with the darker glaze.
