Simulation Of Fining In Specialty Glass

Fining is one of the most important processes in the melting of specialty glass. To understand and improve this process simulations of fining outside the melting tanks must be done. Fining behaviour of glasses can be studied in the laboratory with fining tests, including analysis of gases evolved from a batch, and determination of partial pressure of oxygen, an important analysis when the glass is fined with multivalent ions. These tests can determine the temperature at which fining will occur, what fining agent to use, and what raw material at what grain size distribution should be used.
