Jan Zandhuis studied science at Leyden University in the Netherlands, which later served the artist's glass blowing instruction at Carnegie Mellon University, the Rhode Island School of Design, the Rochester Institute of Technology, the Royal College of Art and the Gerrit Rietveld Academy, from 1959-75. In the emerging Studio-Glass Movement of the late 1950s and 1960s, Zandhuis's work emphasizes mastery in a wide variety of glass techniques including molding, blowing, "lampwork" or changing the shape of glass tubes with heat and pressure, "cold connections" or gluing, and "slip trailing" streams of liquid glass to dry as applied decoration. The artist's work is also in the collection of the Carnegie Museum of Art, the Corning Museum of Glass and the National Gallery of Australia.
