This piece was created by Merritt and her Dragon (a mobile glassblowing studio) located in her backyard.
Each orb is a single gather of glass which allows it to be very light. There is a gather of clear glass then the orb is coated with white and dark multi frit. It is heated up and the blown into a shere, the orb is hit off the blowpipe and a clear hook is applied to the top to finish it off. 
Dimensions are 4.5"x3.5"
MAD Thanks
