A New Silicone Rubber Casting Material Designed for Forensic Science Application

CODEN: JFSCAS

Abstract

The need for an improved silicone rubber casting material has been evident for years. Products currently available must usually be coated or colored to make them opaque so that fine detail can be microscopically observed. A new product manufactured in Sweden has properties that make it superior to other casting materials currently available. Visibility of detail in casts made from shallow marks is dramatically increased because of its reflective properties and uniform opacity. Besides the usual tool mark applications, the material has been found useful in the comparison of firing pin impressions where lighting is a problem. It is beneficial in the examination of shiny surfaces such as extractor marks on cartridge casings and on plastic surfaces.
