ABSTRACT Decolorizcd glasses vary in their approach to neutral color depending upon their and custom of manufacture. Iron, the chief coloring agent in colorless glass, produces several colors. The iron color is first controlled and then neutralized with complementary color or colors furnished by a variety of oxides. The final tint may be neutral or not, depending upon the method of examination, and varies with changing conditions. Thc decolorizing materials are subject to change after the glass is made. These changes are caused by heat and light radiations. Much research on color change is incomplete. The glass composition should be accurately known and the color should represented by spectral transmissions.
