The watermark of a crane (bird) and a turtle, which have long been a symbol of longevity in Japan and are also artistic motifs, are placed in a copper saucer and finished with sulfide treatment.
Cranes and turtles have been a symbol of longevity since ancient times.
The crane is also said to be a bird that symbolizes marital bliss, as it is said that a husband and wife get along well and can stay together for life.
Copper has antibacterial and antiseptic properties, and the more it is used, the darker its color and taste become. Tea utensils made of copper have been considered the best utensils since ancient times, and have a high artistic reputation and value.
The sulfurization process, called "sulfurized ibushi," is a traditional finish that allows the craftsman to obtain the texture created by the color change of the copper alloy over time from the beginning, and its luxurious and heavy color creates a warm space. It is popular both in Japan and abroad, and is often used in temples, shrines, historical architecture, and museums.
