Glasses Melting and Pressing Process
|
Mixed raw material called "batch" is put into a platinum lined pot and melted into amorphous glass. |
Amorphous glass is stirred to insure good homogeneity. |
After casting, the glass is cooled and crushed. Then the refractive indices are measured for process control. The crushed glass is called "Cullet". |
The cullet material shown above is melted again to achieve consistent optical values and properties. |
