GLASS, CHEMICALLY STRENGTHENED GLASS, AND METHOD FOR PRODUCING GLASS HAVING CURVED SHAPE

The present invention relates to a glass in which: the glass is a crystallized glass; the glass has a difference log η−log η0 (dPa·s) between a logarithm log η (dPa·s) of bulk viscosity η (dPa·s) and a logarithm log η0 (dPa·s) of local viscosity η0 (dPa·s) of larger than 0 and 1.8 or smaller, in a t...

Zusammenfassung:	The present invention relates to a glass in which: the glass is a crystallized glass; the glass has a difference log η−log η0 (dPa·s) between a logarithm log η (dPa·s) of bulk viscosity η (dPa·s) and a logarithm log η0 (dPa·s) of local viscosity η0 (dPa·s) of larger than 0 and 1.8 or smaller, in a temperature range in which the logarithm log η0 (dPa·s) of the bulk viscosity η (dPa·s) is 11.4 or larger and 12.7 or smaller.
