After high school, he worked as a molder’s apprentice at a ship’s foundry in Portland. In 1943, Peter Voulkos was drafted into the United States Army during the Second World War, serving as an airplane gunner in the Pacific.

In 1951 Voulkos and Autio became the first resident artists at the Archie Bray Foundation for the Ceramic Arts, in Helena, Montana. It is from his time as Resident Director (1951-1954) that the lineage of his mature work, later in full bloom during his tenure at the Otis Art Institute in Los Angeles, California, can be traced.

In 1953, Voulkos was invited to teach a summer session ceramics course at Black Mountain College in Asheville, North Carolina. After the summer at Black Mountain, he changed his approach to creating ceramics. The artist eschewed his traditional training and instead of creating smooth, well-thrown glazed vessels he started to work gesturally with raw clay, frequently marring his work with gashes and punctures.

In 1954, after founding the art ceramics department at the Otis College of Art and Design, called the Los Angeles County Art Institute, his work rapidly became abstract and sculptural. In 1959, he presented for the first time his heavy ceramics during the exhibition at the Landau Gallery in Los Angeles. This created a seismic reaction in the ceramics world, both for the grotesquerie of the sculptures’ shapes and the genius marriage of arts and craft, and accelerated his transfer to UC Berkeley.

He moved to the University of California, Berkeley, in 1959, where he also founded the ceramics program, which grew into the Department of Design. In the early 1960s, he set up a bronze foundry off-campus, anticipating the metal casted Wurster Hall, and started exhibiting his work at NY’s Museum of Modern Art.

He became a full professor there in 1967, and continued to teach until 1985. Among his students were many ceramic artists who became well known in their own right.

In 1979 he was introduced to the use of wood firing in anagama kilns by Peter Callas, who became his collaborator for the next 23 years. Most of Voulkos’s late work was wood-fired in Callas’s anagama, which was located at first in Piermont, New York, and later, in Belvidere, New Jersey. This unique partnership and the resulting work is considered by many curators and collectors to be the most exuberant period of Voulkos’s career.

At a New York auction in 2001, a 1986 sculpture by Peter Voulkos was sold $72,625 to a European museum.

He died of a heart attack on February 16, 2002, after conducting a college ceramics workshop at Bowling Green State University, Ohio, demonstrating his skill to a live audience.
