Illustrated is a close-up of the interior of an Oribe Mizusashi
by Kakurezaki Ryuichi apprentice; Ishii Takahiro. The interior, truly
highlights the rich diversity that a copper glaze, in this case an Oribe, is
capable of. Though only one glaze, as the glaze matured and pooled into the
bottom of the interior, it has gone from a rich, translucent grassy green
to an opaque boundary of blue-green with black spots being formed by the build up
of high concentrations of copper forming
black metallic crystals. The opaque blue-green has also created an effect
reminiscent of pine-needles floating about the surface. In terms of any Oribe
glaze, I don't think you could have asked for more diversity and testament to the
possibilities of using copper.
For anyone interested in learning more about the
elements, I would suggest watching this short video.
