This Japanese vintage mixed copperware ink silver seal case was made by the metalware artist Zuiho of the Takaoka cooperative. Please see more below. It appears to have been made by the cast copper method. but also appears to be a mixed metal with copper in it. It is made of beautifully moulded chrysanthemums. It is made by a method called copper casting, see more below. It is decorated with silver lacquer as many metal pieces are. It is about 50-60 years old dating to the late Showa period of 1926-1989. It appears to have been sparingly used on the inside. It is in good condition on the outside, there is some wear around the rims where the two pieces meet. We are happy to share the link to the maker's website. Like a kogo, it would be a great decorative piece. It is just a little larger than a kogo. We also have a censer made in the same manner, by a different artist.
SIZE: Diameter 3.12 inches or 8 cm, Height 1.17 inches or 3 cm, Weight 310 grams
On Metals from WIKI
Bronze and related copper alloys are the oldest and still the most popular metals for cast metal sculptures; a cast bronze sculpture is often called simply a ‘bronze’. Common bronze alloys have the unusual and desirable property of expanding slightly just before they set, thus filling the finest details of a mold. Their strength and lack of brittleness -ductility- is an advantage when figures in action are to be created, especially when compared to various ceramic or stone materials
Casting is a group of manufacturing processes by which a liquid material -bronze, copper, glass, aluminum, iron- is -usually- poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solid casting is then ejected or broken out to complete the process, although a final stage of ‘cold work’ may follow on the finished cast. Casting may be used to form hot liquid metals or various materials that cold set after mixing of components such as epoxy, concrete, plaster and clay.
Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. The oldest surviving casting is a copper Mesopotamian frog from 3200 BC. Specific techniques include lost-wax casting, plaster mold casting, and sand casting. Gold is the softest and most precious metal, and very important in jewellery; with silver it is soft enough to be worked with hammers and other tools as well as cast; repoussé and chasing are among the techniques used in gold and silversmithing.
