(under the class definition) Composition specialized for use in preparing, coating or regenerating incandescent mantles, and mantles defined solely in terms of the composition of which they are composed.
(1) Note. The term "mantle" is intended to include all devices which are designed to give off light by being heated to incandescence by a combustion flame.
(2) Note. Included herein are also processes of making mantles which involve no more than preparing or regenerating the composition of which the mantle is composed. For example, this subclass includes processes wherein a textile base is coated or impregnated with a composition classifiable in this subclass and the textile base is then burned off.
