Many effects can be produced via Pepper’s Ghost. Since glass screens are less reflective than mirrors, they do not reflect matte black objects in the area hidden from the audience. Thus Pepper’s Ghost showmen sometimes used an invisible black-clad actor in the hidden area to manipulate brightly-lit, light-coloured objects, which can thus appear to float in air. Pepper’s very first public ghost show used a seated skeleton in a white shroud which was being manipulated by an unseen actor in black velvet robes. Hidden actors, whose heads were powdered white for reflection but whose clothes were matte black, could appear as disembodied heads when strongly lit and reflected by the angled glass screen.
