Eric Franklin‘s sculpture’s glow with a certain life.  Though the series focuses on skulls and skeletons, it isn’t exactly dead.  These skulls are carefully made of flameworked glass, or glass melted and shaped with a torch.  The hollow skulls are then filled with ionized neon, krypton, and mercury gases.  The ionized gases cause the skulls to glow from within complimenting their eery shape.   [via]
