From the William Traver Gallery website:
Yamano's technical mastery and innovations owe much to his study of traditional Japanese metalwork: Yamano rolls thickly blown hot glass over silver leaf to fuse it. He then etches the surface with images -- most often his trademark fish and mountains. He then plates the surface with copper. After, the artist embellishes the blown vessel with hot sculpted and cold-worked glass elements. The resulting pieces are complicated but richly subtle.
"The hanging pieces give me more freedom to deal with space. Still, my concept is the same: a fish, like a tuna or a mackerel, has to swim for its entire life, otherwise it dies. So, I think of the fish as myself. I have to keep doing, keep working, keep going, keep jumping into life."
