text: The uneven rate of cooling (temperature differential) results in the occurrence of mechanical stresses throughout the ribbon of molten glass, which are sufficient to: (i) cause the material to crack, before the molten glass has cooled to ambient temperature; or (ii) result in a brittle material, glass susceptible to cracking during later use, usually by thermal shock.
