Fingerprint is one of the important evidence in forensic science. The ridge
characteristic detail or minutiae of fingerprint can be used to identify individual. There are three
types of fingerprints: visible, plastic and latent fingerprints. Visible and plastic fingerprints can
be seen by naked eye; but latent fingerprint must be developed to make them visible and can be
found on porous, nonporous and semi-porous surfaces. Since powdering is the easiest method to
be used both in crime scene and laboratory especially black powder. The aim of this study was to
find the best black powder available in Thailand to develop the latent fingerprint on various nonporous
surfaces. In this study seven brands of black powders including magnetic powder were
used to develop fresh latent fingerprint on 12 non-porous surface samples.
