This plates measures about 26 centimetres (or 10.5 inches) from rim to rim.
The dramatic "Northern Night" surface is achieved by combining two quite different glazes.
The darker rim 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.
