CURVED PLATE GLASS MOLDING METHOD

摘要

In this invention, when obtaining a curved plate glass G2 by heating a plate glass G1 positioned over a lower mold 11 to mold the plate glass G1 by self-weight deformation, which accompanies the softening of the plate glass G1, the viscosity of the plate glass G is maintained at 10¹⁰ poises or greater during the interval from the start of the plate glass G1 heating until completion of the plate glass G1 molding.
