ABSTRACT:
The present invention is related to the production of glasses in the Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 or Na.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 composition systems containing NiO and TiO.sub.2. Such glasses exhibit a brown coloration when first melted but the color is converted to a green hue after exposure to a particularly-defined heat treatment. The green coloration results from the growth of a small amount of very fine-grained crystallites of nickel spinel (NiO.Al.sub.2 O.sub.3). The crystallized articles can be chemically strengthened utilizing a low temperature ion exchange reaction.
