Working-Point (rotary viscosimeter)

It deals with a viscometric fixed point (value of temperature) at the viscosity η=104,0dPas. The working point describes the temperature when the glass is soft enough for being manufactured in a glass factory by the most current methods.

The determination is realized by a rotary viscosimeter.
