It is expected by bubbling operation of molten glass that glass composition becomes uniform. Air or Ar gas was purged into the molten simulated waste glass, and the drained glass was investigated by Raman spectrophotometry and synchrotron XAFS measurement. As a result, the Si-O bridging structure with a small number of non-bridging oxygen increases by Ar gas purging into the molten glass and also valence of Ce included in the simulated waste glass reduces.
