“I have always loved work that was abundant, filled with stuff,” says Cowan, whose glass assemblages are on view in “Alchemy of Adornment” at the Museum of American Glass at WheatonArts through Dec. 31.Cowan's glass sculptures use recycled, upcycled and second-life American pressed glass. She employs the processes of flameworking, hot-sculpting and glassblowing to create large-scale sculptures that are ornate and have a quality she calls “viral accrual.” “It refers to a kind of lushness that will keep growing and building,” Cowan says. Another term she uses is “horror vacui,” which is defined as a fear or dislike of leaving empty spaces in an artistic composition; the entire surface of the artwork is filled with detail and content.
