As its name suggests, the October “Radiant Reflections” exhibition at the Averitt Center is about glass – glass creations by Jonathan Poirier, photographic designs under glass by Debbie Bailey and the ringing tones of music by glass-harpist Brien Engel. The exhibit is sponsored by Brodie International president Thomas Clark, and the public is invited to Friday’s opening reception at 7 p.m. inside the Main Gallery. Poirier studied glass blowing in Sweden under the tutelage of Ritzman, a master craftsman in the art of glass making.
