It’s all about ceramics when the 47th annual National Council on Education for the Ceramic Arts (NCECA) fires up the George R. Brown Convention Center Wednesday through Saturday, March 20 through 23. Supplementing the conference itself are exhibitions, workshops, lectures and demonstrations — in all, 175 ceramic-related exhibits held in 90 venues, including three juried shows: the NCECA Biennial at the Houston Center for Contemporary Craft (through May 5); NCECA’s National Student Juried Exhibition at the Museum of Fine Arts, Houston’s Glassell School of Art (through March 23); and the Texas State K-12 Juried Student Exhibition at the Downtown Public Library (through April 12). As for the conference itself, Janine Antoni — whose work blurs the line between performance art and sculpture — gives the keynote address, with additional lectures by Bill Bowers, Namita Gupta Wiggers and Clayton Bailey. Look for site-specific instillations from five featured artists; a gallery expo uniting an array of national dealers; Art-Stream Gallery’s appearance in a 30-foot Airstream reconditioned into an exhibition space; and the 21st annual Cup Sale, where you can buy petite pottery for a pittance to raise funds for the NCECA Fund for Artistic Development.
