The years leading up to the turn of the century are considered the golden era of Japanese Cloisonné. In and around Nagoya, Japan, five workshops-studios and their master craftsmen were so highly valued and recognized that they had the honor of being the official purveyors to the Meiji imperial palaces and their court gentry.
Among these revered artists was Ando Jubei, whose works you see above. This particular type of cloisonne is called "Moriage" - a miraculous meeting of enamel and copper. This distinct style of craft became influential... defining the look of the global "Arts and Crafts" movement throughout the early part of the 20th century. Both pieces above are circa 1900.
