Japanese tin ware

Molding process Tin melts at around 235-240 degrees celsius.
Tin ingots are melted in a cauldron and then poured into molds.
Once the tin solidifies, the objects are taken out of the molds and trimmed.
Both the inside and outside surfaces are scraped until they become smooth. As a result, the tin regains its original shine. The shape and the thickness of each caddy is minutely adjusted to achieve the perfect fit and bears testament to the craftsmen's expertise.*Some items such as the gourd shape tea caddy which can not be made with a single mold will be attached after this process.
Handles, spouts and knobs etc. are added before the decoration process. Here the craftsman is making a sake pitcher spout with a hammer.
Decoration These tea caddies are handpainted with enamel or lacquerware. They are then soaked in a nitric acid solution. The painted area is masked but the rest corrodes to achieve a pear-skin pitted effect. The degree of corrosion varies according to the season, so this is a delicate process. The caddies are then washed with water. The painted area stands out in shiny relief and the background is rubbed with black or red natural lacquer. (This is a characteristic process but there are also other decoration techniques).
