Abstract
A glass ceramic or glass-ceramic sheet is formed by progressively reducing the thickness of the sheet by passing the sheet between successive pairs of counterrotating rollers. The average viscosity of the sheet is maintained between 5.times.10.sup.4 and 10.sup.9 P during the sheet forming operation.
