    Abstract

    Over the years police literature has generally recommended plaster of Paris [1] or dental plaster [2] to make casts at crime scenes. Even extremely unsophisticated testing indicates that different types of plaster vary considerably in tensile strength, hardness, and setting times under similar environmental conditions. Test studies indicate that plaster of Paris and dental plaster are the least suitable materials for police use because they are the least resistant to breakage and abrasion [3].
