Inspired by Japanese artifacts, the mokume vase is Tiffany's recreation of Japanese metal work. This vase contains a square with panels of copper, silver and gold on a sterling silver frame. Tiffany and Company created a line of items displaying traditional Japanese metalworking techniques after Christopher Dresser, a long time friend of Louis Tiffany, returned from Japan with several artifacts. In 1878 Tiffany displayed his work at the Exposition Universelle in Paris, France. The international community believed these recreations to be some of the most important and significant metalworking creations of the time.
