I love using the “naked raku” technique of firing.? The surface of the raw clay is coated with a thin layer of slip (known as terra sigillatta), which is then burnished smooth with a soft cloth.? The surface is glowing but not shiny; truly reminiscent of a skin-like quality that I love.? Lately I’ve been experimenting with colorations added to the terra sig.? And I especially love this blue.? Though light in shade , it’s no baby blue, but rather something smoked and crackled and lined just as any aged face ought to reveal.
