Glasses having a low softening point and high toughness. The glasses are alkali aluminoborosilicate glasses having softening points of less than 900° C. and, in some embodiments, in a range from about 650° C. up to about 825° C., and an indenter damage threshold of at least 300 g for glasses that are not chemically strengthened. The glasses are free of alkaline earth metals, lead, arsenic, antimony, and, in some embodiments, lithium. |
