  • Publication number: 20230202901
    Abstract: The present invention relates to a glass in which: the glass is a crystallized glass; the glass has a difference log ??log ?0 (dPa·s) between a logarithm log ? (dPa·s) of bulk viscosity ? (dPa·s) and a logarithm log ?0 (dPa·s) of local viscosity ?0 (dPa·s) of larger than 0 and 1.8 or smaller, in a temperature range in which the logarithm log ?0 (dPa·s) of the bulk viscosity ? (dPa·s) is 11.4 or larger and 12.7 or smaller.
