All students should familiarize themselves with the Ceramics Studio Access Policy, listed below, prior to using the facilities.

CCA's Treadwell Ceramic Arts Center

The Treadwell Ceramic Arts Center is a light-filled, two-story building with generous studios that include dedicated areas for hand building, wheel throwing, and slip casting. Each floor has a long kiln room with a total of 16 electric and 15 gas kilns. The spacious glaze room includes a comprehensive supply of raw materials for glaze mixing, a decal-printing station, ball mills, and a spray booth.

The ventilation system was recently upgraded, and new sink catchments were added, in line with the program's focus on safety and environmental concerns.

The second floor provides dedicated studio areas for juniors and private studios for seniors and graduate students, including a lounge with a small kitchen and computer access. Students fire all their own work in the second-floor kiln room.

California weather allows classes to take advantage of the Ceramics Program's outdoor workspace, which includes a new pugmill/extruder and a historic sculpture garden. The Icebox Gallery is available on a rotating schedule for experimental student exhibitions, and the seminar room is available to students for photographing their work.
