Abstract:
A method for making a glass ribbon that includes: flowing a glass into a caster having a width (Wcast) from about 100 mm to about 5 m and a thickness (t) from about 1 mm to about 500 mm to form an a cast glass; cooling the cast glass in the caster to a viscosity of at least 108 Poise; conveying the cast glass from the caster; drawing the cast glass, the drawing comprising heating the cast glass to an average viscosity of less than 107 Poise and drawing the cast glass into a glass ribbon having a width (Wribbon) that is less than Wcast; and thereafter cooling the glass ribbon to ambient temperature. Further, the cast glass during the cooling, conveying and drawing steps is about 50° C. or higher.
