notes: label: Description (Brief)
content: Decorative "bubble" lamp, about 1950. Brass miniature-screw base with glass insulator. Coiled-tungsten filament. Tipless envelope with plastic cover. Cover is a two-piece plastic shell (upper half is blue, lower half red) with ventilation holes. Glued into a large hole in the top is a tipped-glass vial containing a red fluid (probably methylene-chloride). Heat from the lamp causes the fluid to boil, creating bubbles which rise thru the vial. Gas cools and condenses at the top.
