  • Tensions au polariscope avant recuisson au four VS Technologies
  • Tensions au polariscope après recuisson au four VS Technologies

Hot glass working brings tensions in manufactured pieces.

These tensions can cause mechanical fragility.

This is why one must :

detect these tensions when they appear

reduce them through fire annealing

eliminate them through complete furnace annealing

check their absence before delivery


Polariscope highlights tensions with color lines through glass.
