1. A laminated glass pane, comprising:
a first glass sheet having a first composition;
a second glass sheet having a thickness between at least 0.3 mm and at most 1.5 mm, the second glass sheet being made of a lithium aluminum silicate glass and having a second composition that differs from the first composition; and
a polymeric layer having a thickness between at least 0.5 mm and at most 1.7 mm, the polymeric layer positioned between and bonding the first and second glass sheets to one another,
wherein the first and second compositions are, in a viscosity range between 107 dPa·s and 1010 dPa·s, matched so that temperatures at which the first and second glass sheets have a same viscosity only differ from each other by not more than 50° C.; and
wherein the second glass sheet comprises a lithium aluminum silicate glass having:
a Li2O content from 4.6 wt % to 5.4 wt %;
a Na2O content from 8.1 wt % to 9.7 wt %;
a Al2O3 content from 16 wt % to 20 wt %; and
a B2O3 content from 0 wt % to 0.9 wt %.
