Compositions of commercial amber glasses are reviewed briefly. Experimental results for variations in coloring ingredients are shown to affect not only the color, but also the fining. One of the major factors in determining color is the base composition which, contrary to previous reports, is shown to require high silica and low alkali contents for greatest intensity and stability of color. Other results show that color is intensified by the presence of fluorides and that added iron is unnecessary to the development of strong stable colors.
