Unformatted text preview: ♦ Melting point – The temperature where the material is fluid enough to be considered a liquid. This corresponds to a viscosity of about 100 P. (The melting range is η between 50 and 500. Compare with water which has η = 0.01P) ♦ Working point – The temperature corresponding to 10 4 P. At this temperature glass fabrication operations can be carried out. (The working range is η between 10 4 and 10 8 P)...
