This piece was created by Merritt and her Dragon (a mobile glassblowing studio) located in her backyard in Cincinnati. 
Others would call this a paperweight but not M.A.D. these are Dragon Eggs! This egg was created by picking up a sad broken orbs that had been trashed after cracking. Then clear glass is gathered to complete the piece. Before it goes into the annealer the bottom is heated and stamped.
Dimensions are 2.5"x 3"
