Small black-dyed copper plate with hammer pattern Shingetsu

A small plate (φ100mm) with a hammer pattern made of pure copper is made black. The oxide film will appear black, so do not expose it to acidic substances (lemon, vinegar, etc.). The film will come off and the underlying copper will be visible. Please note that it may peel off due to impact etc. Please note that the expression/dimensions are different for each item. Brass has good heat conductivity, antibacterial properties, and is said to be hygienic. For daily use, you can simply wash it with a neutral detergent. It is also interesting to see how the color darkens and dulls over time. made in HAYAMA
