A method for viscosity measurements of glasses and glass pastes was analyzed. The method was based on an indentation test carried out at a constant penetration speed. The viscosity value was calculated from the recording of the load-displacement curves. The specimens required for the study were prepared by melting glass and glass paste flowing in cylindrical molds.
