California-based artist Sterling Ruby and Japan-based artist Masaomi Yasunaga are separated by the Pacific Ocean, but this show brings them together as two innovative masters of ceramics. Made of earthen matter, the basins, baskets, vessels, bowls, animals, shells, and flowers on display are fabulously delicate and otherworldly. And no wonder, both artists have been inspired by archaeology and excavation. Recalling his roots in Amish Pennsylvania, Ruby sees humility in the preservation and use of objects transformed by the earth. Yasunaga sees excavation as a way to understand and produce finished work. The idea of accretion—in terms of color, patina, and surface matter—is alive in this art. —E.C.
