Redox Measurement GS Rapidox II™

Measuring REDOX state in glass melts, introduced by GS in 2005, helps to better understand fining of glass, and glass color in particular.

We measure the REDOX reaction equilibrium – direct p(O2) measurement of:

  • iron
  • antimony
  • cerium
  • chromium
  • sulphur

whereas the measurements are fully automatic and computerized.
