A method of determining the dynamic viscosity of glass by measuring the elongation a glass fibre under a defined uniaxial stress. In addition the viscosity-temperature relationship and the dependence of the viscosity on the thermal history can be checked. The theoretical basis relation and the apparatus including the method of measuring are specified.
