Correct, Mrs. Potato Head!
By the way:
A daguerreotype (original French: daguerréotype) is one of the earliest photographic processes, developed by Jacques Daguerre, in which the image is formed by amalgam i.e. a combination of mercury and silver. Mercury vapor from a pool of heated mercury is used to develop the plate that consists of a copper plate with a thin coating of silver rolled in contact that has previously been sensitised in iodine vapor (later sensitivity was increased by using the other halides - chlorine and bromine to form silver chloride and silver bromide crystals reducing the exposure time to about one minute).
