Fg. Rios et Ji. Thornton, REDUCTION OF SPECULAR REFLECTANCE ON PROJECTILES AND TOOLMARKS BY AMMONIUM-CHLORIDE FUMING, Journal of forensic sciences, 38(4), 1993, pp. 840-842
A method for reducing specular reflectance from metallic surfaces in w
hich ammonium chloride is used as a fuming reagent is described. This
method has the advantage of being easily controlled, and is rapid. The
deposit of ammonium chloride salt on the metallic surface is easily a
nd effectively removed by washing.
