Naked Raku achieved by applying terrasigilata to bone dry coiled vessel and burnishing to make a shiny sealed surface. After bisque firing a crack off slip is applied and then exactly 24 hours later a clear glaze applied on top.
The black marks are made using sgraffitto, carving through the glaze and slip.
The work is then Raku fired and then smoked in sawdust. After removing from the sawdust and plunging into water, all the glaze and slip “crack off” returning the surface to the burnished unglazed but crackle smoked surface.
