1. A single copper sheet is hammered into shape and then cleaned to remove any oil or other contaminants.
2. Soaked in a sulfurizing solution to form an artificial rust coating.
3. Next, the black rust is polished off from the entire surface of the sake cup, taking into consideration the design and coloring of each piece. The black color is left only on the hammered surface to accentuate the shading.
4. Finally, the piece is soaked in boiling color solution made by traditional technique to develop a golden-brown color.
The color is brighter than that of ordinary sulfurized brown copper. As it is carefully used, it becomes more austere and atmospheric, and its color develops into a deeper hue.

In Japan, gold, silver, copper, tin, and iron are called "Gokin (five metals)" and have been used as materials for metalworking since ancient times. Each metal has a different luster, workability, strength, thermal conductivity, heat retention, moisture resistance, corrosion resistance, etc., and techniques to utilize these characteristics have developed in various regions.From daily necessities such as pots, kettles, and accessories to works of art that represent the times such as tea ceremony utensils, Japanese swords, and Buddhist bells, a wide variety of metalwork has been produced in each era.View more Metal items
