A method is described by which the viscosity of glass can be estimated in the range 100 to 450 poises by determining the relationship between temperature and the quantity of glass in fiber form which can be drawn from an orifice in unit time. Results are based on a comparison with an arbitrarily chosen standard glass. The method is relatively rapid, yields good precision, and can be used to make samples of fibers valuable for other tests.
