1. A method comprising:

  • contacting a molten microwave absorbing glass with a molten microwave transparent glass in a double isopipe fusion process to form a glass laminate;

    exposing an area of the glass laminate to microwave radiation, wherein;

    the exposed area of the glass laminate glass is near a bottom core isopipe root of the double isopipe fusion process;

    the glass laminate comprises a microwave absorbing layer and a microwave transparent layer, and a microwave loss tangent δ

    H of the microwave absorbing layer is at least a half order of magnitude larger than a microwave loss tangent δ

    L of the microwave transparent layer, at least at one or more temperature points at which the glass laminate exhibits a viscosity of between approximately 1×

    102 poise and approximately 1×

    10133 poise; and

    in the exposed area of the glass laminate, each of the microwave absorbing layer and the microwave transparent layer is at a temperature above a glass transition temperature TG of the respective layer prior to exposure to the microwave radiation.
