Jon Gietl is Ginny Snodgrass's husband who is a glassblower and has worked with Ginny for many years.Jon carrys on the techniques of his father-in-law, Bob Snodgrass, the original discoverer of silver and gold fume techniques in glassblowing. These silver fumed chillums are recognizably his father's original glass pipe skull designs. These small skulls are nice chillums for on the go. Chillums are one of the oldest pipe designs known to humankind. Jon sets his Top Hat skull chillums apart from Bob's, by making these skull face details glow bright green under the UV light and a bonus alien skull with glowing green eyes on the back.
