Abstract: A method includes supplying a conjoined molten glass stream to an overflow distributor. A cross section of the conjoined molten glass stream includes a first cross sectional portion and a second cross sectional portion. The first cross sectional portion includes a first glass composition. The second cross sectional portion includes a second glass composition different than the first glass composition. The first glass composition is flowed over a first transverse segment of a weir of the overflow distributor. The second glass composition is flowed over a second transverse segment of the weir of the overflow distributor.

Abstract: A glass manufacturing apparatus can include a conduit connected to a delivery vessel and an inlet of a forming vessel. The conduit includes a closed sidewall surrounding a channel extending in a flow direction of the conduit. The closed sidewall is continuous from the delivery vessel to the inlet of the forming vessel to define a closed atmosphere from the delivery vessel, through the conduit, and through the inlet of the forming vessel. The glass manufacturing apparatus can include a heating enclosure including a heating wall and a first heating element. The heating wall surrounds a chamber within which the conduit extends. The first heating element is positioned within the chamber between the heating wall and the conduit to increase a temperature within the channel. Methods for manufacturing a glass ribbon with a glass manufacturing apparatus are provided.

Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.
