More than 70 Bay Area ceramists and glass-blowers–many of them award winners–will participate this month in their annual spring exhibition and sale. On Sunday, June 17, the Association of San Francisco Potters and Glass Blowers celebrates a quarter-century of excellence at the Hall of Flowers in San Francisco’s Golden Gate Park. The following Sunday, June 24, you can see 33 of these artists at work during open houses and demonstrations at their studios and galleries. Functional works–bowls, plates, vases, teacups–will be shown, along with one-of-a-kind sculptural or museum pieces. You’ll see stoneware, porcelain, earthenware, raku, and handblown glass. Everything will be for sale; prices range from less than $10 for many cups, plates, and bowls to around $1,000 for some exhibition pieces, including the work of individuals whose creations are available only in prestigious galleries and museums. Pieces on a sale table will be continuously discounted during the day. The Hall of Flowers is in Golden Gate Park, on Ninth Avenue off Lincoln Way. Show hours are 10 to 5; admission is free. The following artists will open their studios and galleries on June 24 between 11 and 4. Unless noted, telephone numbers are area code 415.
