12. GLASS PROPERTIES Important temperatures in glasses are defined in terms of viscosity:
Melting point: viscosity = 100 P (poises, 0.1 Pa-s), below this temperature glass is liquid
Working point: viscosity = 104 P, glass is easily deformed
Softening point: viscosity = 4x107 P, maximum T at which a glass piece maintains shape for a long time
Annealing point: viscosity = 1013 P, relax internal stresses (diffusion)
Strain point: viscosity = 3x1014 P, above this viscosity, fracture occurs before plastic deformation
Glass forming operations – between softening and working points
