How did they build the Fireworks of Glass in the Indy children's museum built?

Context:
Fireworks of Glass Tower and Ceiling, also known as Fireworks of Glass, is a blown glass sculpture installation in the permanent collection of The Children's Museum of Indianapolis located in Indianapolis, Indiana, United States of America. The tower sits on a glass base, a pergola ceiling, and rises through the center of the museum's spiraling ramp system. Created by Dale Chihuly in 2006, it is his largest permanently installed glass sculpture. Beneath the tower is an accompanying exhibit that describes the sculpture and the process by which it was made. The tower and pergola ceiling are two distinct accessioned objects in the Children's Museum's collection. 
Fireworks of Glass and Pergola Ceiling is a 43-foot tower composed of 3,200 pieces of red, yellow, and cobalt blue blown glass and a pergola ceiling made up of 1,600 pieces of multicolored glass. On the tower, two to four feet pieces of twisted glass are situated on a metal armature suspended by steel cables. The tower rests on a glass plate over a pergola ceiling filled with other pieces of glass. Each piece of glass was individually blown by a team of glassblowers based out of Chihuly's studio in Tacoma, Washington. .<|im_end|>
