mantle in Italian

(malacology) The body wall of a mollusc, from which the shell is secreted. [from 15th c.]

A gauzy fabric impregnated with metal nitrates, used in some kinds of gas and oil lamps and lanterns, which forms a rigid but fragile mesh of metal oxides when heated during initial use and then produces white light from the heat of the flame below it. (So called because it is hung above the lamp's flame like a mantel.) [from 19th c.]
