notes: label: Description (Brief)
content: A length of GE "Lucalox" tubing. Characteristics: milky-white polycrystalline alumina tube. This sintered-ceramic material was developed in the late-1950s by GE's Research Lab in Schenectady. It is used to make arc-tubes for high-pressure sodium lamps because it can resist the corrosive affects of sodium. Despite its opaque appearance (due to light scattering at crystal grain-boundaries) it is about 95% transmissive of light.
