ABSTRACT:
A method of controlling reaction paths of glass batch components added to a resident glass melt is provided, including the steps of providing a plurality of raw material batch components according to a batch recipe, selectively combining a portion of the batch components into a first combination material having a melting temperature in a range of 60 to 90% of a resident melt temperature (K) and a viscosity3a melt viscosity/100, and selectively combining another portion of the batch components into a second combination material having a reaction temperature in a range of 60 to 100% of the resident melt temperature, the second combination material being capable of forming an intermediate compound via a solid state reaction before reacting with the glass melt. The first and second combination materials and any remaining batch components are mixed and introduced into a glass melter.
