Much has been written about the passing of glass artist Stephen Rolfe Powell. Most have focused on his finished art, the various colorful, bulbous vessels that made him famous. Not enough has been said about his process and the people who helped him (blown glass is a team sport). Powell was foremost a teacher at Centre College, with a chosen few of his students becoming his assistants. “Legacy” focuses on them, with works by Jonathan Capps, Matthew Cummings, Paul Hugues, Adam Haigh, Patrick Martin, DH McNabb, Paul Nelson, Che Rhodes, Thomas Spake, Sam Spees, Nate Watson and Brook F. White Jr. The reception is Friday, Sept. 20 from 5:30 to 8:30 p.m., the day before Centre is holding a public memorial service for Powell. —Jo Anne Triplett
