    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
