What is Shibuichi?
Shibuichi is an alloy which can be patinated into a range of subtle muted shades of blue or green. Its name means "one-fourth" in Japanese and indicates the standard formulation of one part silver to three parts copper, though this may be varied according to the desired effect. A 5% silver / 95% copper alloy is also marketed as "shibuichi" A wide range of colours can be achieved using the whole range of alloy compositions, even above 50% silver. It is a common misconception that both copper and silver oxides form but in fact a detailed study has shown that only copper oxides are formed on the copper rich regions of the materials microstructure while the silver rich regions are left largely untouched.
