1. A laminate comprising:
a first complexly-curved glass substrate comprising a first surface, a second surface opposite the first surface, and a first thickness therebetween;
a second complexly-curved glass substrate comprising a third surface, a fourth surface opposite the third surface, and a second thickness therebetween; and
a polymer interlayer affixed to the second surface and the third surface, wherein:
the first complexly-curved glass substrate is hot-formed and curved along at least a first axis and a second axis, and
the second complexly-curved glass substrate is cold-formed against the first complexly-curved glass substrate via the polymer interlayer at a temperature that is 200° or more below a softening point of the second complexly-curved glass substrate.
 
17. A laminate comprising:
a first complexly-curved glass substrate comprising a first surface, a second surface opposite the first surface, and a first thickness therebetween;
a second complexly-curved glass substrate comprising a third surface, a fourth surface opposite the third surface, and a second thickness therebetween; and
a polymer interlayer affixed to the second surface and the third surface, wherein:
the first complexly-curved glass substrate is hot-formed and curved along at least a first axis and a second axis,
the second complexly-curved glass substrate is cold-formed against the first complexly-curved glass substrate via the polymer interlayer at a temperature that is 200° or more below a softening point of the second complexly-curved glass substrate,
from second complexly-curved glass substrate being cold-formed, the third surface experiences tensile stresses and the fourth surface experiences compressive stresses, and
prior to being cold-formed, the third surface and the fourth surface exhibit either: (a) no appreciable compressive stress; or (b) equal compressive stresses.
