Abstract
A review is given of the methods for measurements of glass viscosity by penetration methods. Three temperatures were selected to investigate the effect of penetration rate on stress at a knee. The experimental results indicate that there exists a critical penetration rate at each temperature. Glass behaves like a Newtonian fluid below this rate. The higher the temperature, the larger the critical penetration rate.
