“Copper coloring”, the unique metal texture realized through evolution of traditional techniques, from Takaoka, JAPAN.
Momentum Factory Orii was originally founded in 1950, specializing for copper coloring. “Copper coloring" is traditional techniques for developing vivid colors on copper and brass by oxidation. We also sometimes use sake, vinegar, rice bran and radish for old traditional techniques.
We have evolved our techniques to bring forth the beauty as new building metal materials, such as use in customized works installed at hotels, restaurants and commercial facilities. We think that the new uses are the foundation for the next generation.
