Cloisonné is an ancient metalworking technique, perfected in China and later adopted in Japan. It involves creating decorative designs on metal objects using enamel, glass, or stone inlays within compartments defined by thin metal wires or strips. The process requires meticulous craftsmanship and multiple firings to achieve the vibrant colors and intricate patterns characteristic of cloisonné ware.
 
Japanese cloisonné, particularly from the Meiji period (1868-1912), is highly prized for its technical sophistication and artistic merit. During this era, Japanese artisans pushed the boundaries of cloisonné, creating pieces with unparalleled detail and complexity. These items were often made for export, catering to Western tastes while showcasing Japan's rich cultural heritage. This particular piece appears to be from Meiji Period time period.
