Opening Friday: With the aid of fellowships and grants, artists may refine their work or set off in entirely new directions, as happened last year at the Northern Clay Center. Three winners of project grants from the Jerome Foundation -- Nathan Bray, Marion Angelica and Dustin Yager -- changed the glazes, geographical inspiration and purpose of the pots they made. Fellowship winners Tyler Aymond, Alex Reed, Kip O'Krongly and Margeaux Claude also altered their media and design sources during working residences at the center. Their new ideas and products will be showcased in exhibitions opening this weekend. (Artists talk 4:30 p.m. Friday; opening reception 6-8 p.m. Friday, free. Northern Clay Center, 2424 E. Franklin Av., Mpls. 612-339-8007 or www.northernclaycenter.org.
