Glass is provided so as to have high visible transmission and/or fairly
clear or neutral color. In certain example embodiments, the clear glass
includes a low amount of iron coupled with zinc oxide and/or erbium oxide
in amounts designed to provide a neutral color. While the erbium oxide is
used to provide for neutral color, the zinc oxide binds sulfur into
whitish-colored zinc sulfide thereby reducing the amount of sulfur that
binds/bonds with iron in the glass to form sulfides of iron which is/are
brownish in color. Thus, the use of the zinc oxide helps make the glass
more neutral in color. In certain example embodiments, the use of the
erbium oxide brings the a* color value of the resulting glass closer to
zero, whereas the use of the zinc oxide brings the b* value of the
resulting glass closer to zero.
