If you're wondering what exactly you're looking at, these are large marbles handmade from borosilicate glass and the manipulation of 99.999% pure silver fume and particles. When the piece is almost complete it is allowed to cool to 1000 degrees Fahrenheit then is brought back up to a specific temperature. This action "strikes" the silver producing the different colors you see.*
What I find really fascinating are not only the pieces themselves but that Sean is self-taught and is now a full-time glassblower. It's really inspiring to read about artists who were able to take their craft from a hobby to a full-time career, even more so when they did not train for it.
