Abstract

In 1949, Poole developed an empirical relationship which expressed the logarithm of viscosity of silicate melts as a function of the hyperbolic sine of the reciprocal absolute temperature, e.g., log. visc. = Sinh M/T.

Poole showed the validity of this relationship for normal soda-lime glasses. This paper extends the relationship to variations in composition making possible the prediction of viscosity as a function of temperature for a wide range of three and four component glass systems. Graphs are presented to facilitate calculations. The relation has been verified by comparison with published data. The structural and theoretical implications of this relationship are compared with present theory.
