Abstract: Methods for manufacturing glass articles having a target effective coefficient of thermal expansion CTETeff averaged over a temperature range comprise selecting a glass core composition having an average core glass coefficient of thermal expansion CTEcore that is greater than the target effective CTETeff and a glass clad composition having an average clad glass coefficient of thermal expansion CTEclad that is less than the target effective CTETeff; and manufacturing a glass laminate comprising a glass core layer formed from the glass core composition and two or more glass cladding layers fused to the glass core layer, each of the two or more glass cladding layers formed from the glass clad composition such that a ratio of a thickness of the glass core layer to a total thickness of the two or more glass cladding layers is selected to produce the glass laminate having an effective coefficient of thermal expansion CTEeff that is within ±0.5 ppm/° C. of the target effective CTETeff.

Abstract: According to one embodiment, a method of forming a laminated glass ribbon may include flowing a molten glass core composition and a molten glass cladding composition in a vertically downward direction. The molten glass core composition may be contacted with the molten glass cladding composition to form the laminated glass ribbon comprising a glass core layer formed from the molten glass core composition and a glass cladding layer formed from the molten glass cladding composition. Core beads located proximate an edge of the glass core layer and clad beads located proximate an edge of the glass cladding layer may be compressed while the glass core layer and the glass cladding layers have viscosities greater than or equal to the viscosity at their softening points as the laminated glass ribbon is drawn in the vertically downward direction.

Abstract: A system includes an overflow distributor (200) including a weir (245, 247). The system further includes a thermal exchange unit positioned in proximity to the weir. The thermal exchange unit (300) includes a tubular focusing member (310) and a thermal member (330) disposed at least partially within a lumen of the focusing member. The focusing member extends distally beyond a distal end of the thermal member by a distance It. In an embodiment the thermal exchange unit comprises several focusing members and thermal members to control a thermal profile of a glass stream flowing over the weir, particularly of a portion of the glass stream in contact with the weir.
