Homemade Quartz Ultraviolet Lamps
Quartz glass tube filled with Sodium Fluoroscein.
Glows opaque yellow green under UV radiation (sunlight, blacklight, and
cold quartz lamp irradiations,
as well as electrical discharges).
Many thanks to Rick Seville for the quartz envelope.
Homemade bulb made from Light Bulb salt shaker. Quartz germicidal
Sodium Fluoroscein, and insulating oil on top. Thanks to John
"Grizzy" for the shakers!
