Abstract
In the process of producing a glass, a glass melt is formed from an initial glass batch, an inorganic or organic peroxide is include in the glass melt as a refining agent in an amount suitable for refining, and then the glass melt is refined at a refining temperature equal to or greater than a decomposition temperature of the inorganic or organic peroxide. The inorganic peroxides used in the glass-making process only include cations that are already present in components of the initial glass batch. The organic peroxides used in the glass-making process are chosen so that the organic residue remaining in the melt after release of oxygen is decomposed to volatile water and CO.
