Powder: This method to reveal fingerprints should only be used on callous and impermeable surfaces such as marble and glass. It is highly advisable to use a powder that is easily recognizable on a surface the print was made. Two representations of this would be to use talcum powder on a dark surface and carbon powder on a light surface. Use a thin brush such as a paint brush and spread the powder on the affected area of the print until a distinctive print can be seen. Then, take a piece of tape, collect the powdered print with the sticky side, and place this print on a opposite colored piece of paper.
Superglue Fuming: A process of revealing fingerprints through the evaporation of super glue. This method may be used for a variety of surfaces such as porous wood to impearmeable glass. The vapor of the super glue sticks to the oils of the fingerprint and exposes it to the naked eye. An overall great method.
