Heat-regulating glass bending apparatus and method

A sag-bending system, comprising:

• a sag-bending glass support mold having a quadrilateral shape, a collective upper surface, and a periphery, the support mold comprising:
• a plurality of rib members extending in a first direction, each of the plurality of rib members having a curved upper surface shaped to form the collective upper surface having a position and shape to support a quadrilateral-shaped sag-bent glass sheet into a desired contour, each of the rib members further having a lower surface;
• a plurality of support members extending in a second direction between at least two of the plurality of rib members, the second direction traverse to the first direction;
• and
• wherein the periphery of the support mold is formed by the edges of the rib members;
• and
• a perimeter thermal manager sized and positioned to surround, to extend at least partially over, and to extend at least partially under the periphery of the support mold, the thermal manager comprising:
• an upper portion sized and positioned to extend over the periphery portion of the collective upper surface, the upper portion extending over the upper surface of at least one rib member;
• and
• a lower portion sized and positioned to extend under the periphery portion of the support mold, the lower portion extending under the lower surface of the at least one rib member.
