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 vase that had been trashed after cracking. Then gathered clear glass to complete the piece. Before it went into the annealer the bottom is heated and stamped.
Dimensions are 2.5"x 3"
