As TiO2 is replacing SiO2 it has a slight suppressing effect on the viscosity until the limit when Na2O/TiO2 ratio is less than 2, indicating a transformation of the structure of TiO2, a remarkable increase in the fragility and viscosity is observed for the calculated low temperature region. The change is not as evident for the high‐temperature region. CaO replaced by TiO2 gives almost no effect on the viscosity, however, as it approaches Na2O/TiO2≈2 it tends to crystallize at temperatures of 1000‐1050 °C.
