Dale Chihuly has gained international fame for his dramatic glass sculptures. But the most visible example of the Chihuly Collection, which opens July 11, is not glass. A 20-foot Chihuly sculpture made of Polyvitro, a polyurethane material, will sit outside the museum-quality facility, the first in the world to feature a broad permanent display of the Seattle artist's works, at 400 Beach Drive, St. Petersburg. The 235 pieces in Rose Crystal Tower were made by pouring the polyurethane into molds made from glass so they appear to have been cut and sculpted. Katee Tully, executive director of the Morean Arts Center that will own and operate the Chihuly Collection, said it can weather hurricanes, has security camera protection and "is about as vandal-proof as something can be." Installing the sculpture are, from left, Ryan Shinn and Gene Broadgate of Chihuly Studio in Seattle. For more news on the arts in Tampa Bay, read the Critics Circle at blogs.tampabay.com.
