Space Nebula Keyring

Very simple but eye-catching, the borosilicate glass beads on this keyring are so pretty with the rainbow of colors encased in clear which gives the illusion of depth, like reflections on water. The bead is the work of artisan lampworker Elizabeth Girod and it is made of borosilicate glass, which is a special kind of glass which is actually more durable than normal glass - it is the same kind used in Pyrex and is less dense than ordinary glass and it also requires a much higher temperature to melt compared to ordinary silicate glass.
