The sample rod prepared in this way looks like a uniaxial crystal with optical
anisotropy . Using a polarimeter , a positive birefringence was observed , uniform
throughout the sample , with the light traveling perpendicular to the pulling axis ,

Sample rods of composition ( by weight ) 70 % SiO2 , 23 % B2O3 , and 7 %
Na2O were stretched over a gas torch and cooled under load , and birefringence
was measured as a function of sample temperature . Because of this method of ...

After the sample glasses were stretched at 900°C for 5 min and annealed , they
report that the structural birefringence often reached the order of 20 , 000 nm / cm
. The birefringence change of these samples was measured as a function of heat
