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.
Claims16
A method comprising:
- supplying a conjoined molten glass stream to an overflow distributor, a cross-section of the conjoined molten glass stream comprising a first cross-sectional portion and a second cross-sectional portion, the first cross-sectional portion comprising a first glass composition, the second cross-sectional portion comprising a second glass composition different than the first glass composition;
- flowing the first glass composition over a first transverse segment of a weir of the overflow distributor;
- and
- flowing the second glass composition over a second transverse segment of the weir of the overflow distributor,
- wherein at least one of the first transverse segment of the weir or the second transverse segment of the weir comprises less than an entire effective width of the weir.
A method comprising:
- supplying a first glass composition and a second glass composition to a divided delivery tube comprising a plurality of flow channels;
- and
- flowing each of the first glass composition and the second glass composition down a forming surface of an overflow distributor to form a glass sheet comprising the first glass composition and the second glass composition;
- wherein each flow channel of the divided delivery tube corresponds to a determined region of the glass sheet disposed at a determined transverse position relative to a width of the glass sheet and a determined axial position relative to a thickness of the glass sheet.
