Bringing out a high-end appearance that ages beautifully. Introducing a technology used across a wide range of industries.
The "sulfurized smoked finish" is a technique that reproduces the way the surface of copper alloys changes to a brownish color over time. Since it is done by hand, it is possible to adjust the color depending on the application and polishing methods. The deep and heavy feel of this finish is often seen in temples, shrines, and museums, and its calm atmosphere is preferred for the interiors and exteriors of corporate offices and high-end brand stores. 【Features】 ■ Reproduces the way the surface of copper alloys changes to a brownish color over time ■ Enhances the color and texture inherent to the metal itself ■ Can be applied to relatively large products *For more details, please refer to the PDF document or feel free to contact us.
