I just got an interesting photo from Tommy in Germany, who wears a 4mm (about 6ga) glass bar, made for him by the talented folks at Gorilla Glass. The piercing started as a normal 14ga industrial, and over five years Tommy stretched it up using normal steel rings, never finding any jewelry he really liked until discovering Gorilla Glass. Much of the time he wears two separate short glass plugs, but here in the picture he’s using the 55mm (just over 2″) long glass bar with round ends, secured with O-rings. The bar is quite solid, having survived a few falls, and I suspect with that any guaranteed-concussion blow to the noggin hard enough to break the bar, the broken bar would be the least of his worries.
