Dead Reflection.  A rough surface with virtually no reflective properties; matte surface. Rays of light are diffused and reflect off at all angles; opposite of mirror finish in which all rays are parallel from a very smooth surface. Dead reflection is created by abrasive blasting, or other matte producing techniques.  See reflectiveness, matte.
