A simple formula is provided to estimate viscosity of glass using parallel plate viscometry well above the upper limit of the recommended range. The formula is based on computational studies that account for viscoelastic material behaviour and frictional slip that justify using linear interpolation to estimate viscosity between established upper and lower bounds.
