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 red frit and using tweezers to give it a swirly and then gathered clear glass to complete the piece. Before it went into the annealer the bottom is heated and stamped.
Dimensions are 2.25"x 2.25"
