Welsbach
Welsbach Wels"bach, a. Of or pertaining to Auer von Welsbach or the incandescent gas burner invented by him.

{Welsbach burner}, a burner in which the combustion of a mixture of air and gas or vapor is employed to heat to incandescence a mantle composed of thoria and ceria. The mantle is made by soaking a ``stocking'' in a solution of nitrates of thorium and cerium (approx. 99:1), drying, and, for use, igniting to burn the thread and convert the nitrates into oxides, which remain as a fragile ash. The light far exceeds that obtained from the same amount of gas with the ordinary fishtail burner, but has a slight greenish hue. [Webster 1913 Suppl.]
