Glassblower Ralf Marlok's favourite piece is a thick-walled glass vase from 1976. The exhibit comes from the hand of Dale Chihuly, to this day the best-known living glass artist in the USA. The artist is best known for his oversized installations and floral glass sculptures in Venice, Israel, the Czech Republic and the USA, among other places. "You quickly get into conversation with American visitors to the museum," says Marlok, who works as a glassblower at the museum.
