Claim 0:
1. A method of forming a ribbon of glass comprising:
supplying molten glass into a gap separating a pair of forming rollers,
the molten glass having a viscosity of 0.01 Poise to 3000 Poise, and
each of the pair of forming rollers having an outer diameter of 20 mm to 80 mm;

forming the ribbon of glass from the molten glass; and
(i) reducing a rate of temperature decrease of the ribbon of glass vertically before the ribbon of glass cools to a glass transition temperature, and/or (ii) increasing the rate of temperature decrease of the ribbon of glass vertically after the ribbon of glass has cooled to the glass transition temperature.
