ABSTRACT:
Incandescent mantles of improved strength and durability are provided for use with fuel-burning lanterns. The mantles are characterized by the use of a hydroxide mixture on the mantle sack of which the primary component is yttrium hydroxide together with a critical proportion of cerium hydroxide, whereby on conversion of the hydroxides to the corresponding oxides of the incandescent mantle, illumination is provided of a candle power comparable to that of the standard thorium oxide-cerium oxide mantles while at the same time obtaining a mantle of greatly increased strength and durability, as needed especially for use with fuel-burning lanterns where the mantles are subjected to frequent mechanical shocks.
