Marble Slurry Powder are Using Visualization on Latent Fingerprints on Different Surfaces

Abstract

Marble industry produces large amount of marble slurry. Home flooring & furniture processing stages are also produces slurry. This waste is dumped on the open land creates a lots of environmental problem so the use of this waste marble slurry powdered to developed latent fingerprints & solved crime. This waste powder is easily available on the construction site and use as a latent fingerprint development powder. This Study presents a new marble slurry powdering method which is simple for the development of latent fingerprints on Porous or nonporous surfaces. Ten Samples are successfully developed and collected to the different porous & nonporous Surfaces i.e. Paper, Plywood, Plastic box, Nonporous plastic surface, Nonporous wooden surface, Iron, nonstick utensil, leather, Umbrella nonporous cloth, Stainless steel. The fine particles of marble slurry Powder get combined with the fatty acid & oil present in the sweat of a fingerprint and latent fingerprint pattern can be clearly observed on the surface by using marble slurry powder. Studies shows that it gives perfect results on most of the surfaces with clear fingerprints pattern and ridges.
