no worries. A gas mantle is a device used in gas lamps to produce bright white light through incandescence by heating a fabric mesh impregnated with metal salts when gas is burned. so it is like a net. It is used in camping lights and until around 85, they put Thorium in them for a better light. Check out the video I linked to from Technology Connections.
