A beautifully shifting rainbow-colored teacup.
This piece, which was finally completed through secca’s original research, generates a texture that cannot be achieved by using the usual glaze firing method.
The iris, which is like a microcosm, is composed of structural colors(*), and allows for perceiving various colors that emits light of a specific wavelength. With no coloring on its surface, the teacup is called a “colorless teacup”.
The design of the structural colors is achieved by layering vacuum deposition processing, an industrial technique of titanium, on an hand-twisted teacup.
We feel there is a conflicting and implicit boundary between craft and industry, with craft seemingly refusing to interfere with industrial technology.
Crafts are only born from the act of creating by trained hands, and only techniques and materials that have been used continuously for over 100 years are recognized as such.
However, even among the technologies developed in the industry, there are many exceptional technologies that have been cultivated through extensive research and practice by the hands, senses, and passion of people.
If craft aims to search beauty created by people, and if there is a potential for such beauty to evolve in industrial techniques, it is a natural act to proactively blend with craft’s traditional techniques.
This work is also a concept in itself.
(*Structural color refers to a spectrally induced coloring phenomenon caused by microstructures at or below the wavelength of light. Familiar structural colors include compact discs and soap bubbles. It appears to be colored due to light interfering with the fine structure but are actually colorless.)
