Abstract
A method of increasing efficiency in glass batch melting by controlling the reaction paths of batch constituents as they melt, preventing early formation, flow, segregation and pooling of low-viscosity liquids. The glass batch raw material components are separated into first and second portions with different respective compositions, resulting in first and second respective compositions having first and second respective reaction paths. The respective portions are combined with remaining raw materials to define a mixture which is then introduced into the melter and reacted to yield a homogeneous glass melt. The first composition has a first melting temperature having a first reaction path resulting in a first liquid having sufficient viscosity to minimize flowing. The second composition has a second melting temperature and the first liquid fluxes the second composition to yield a molten glass composition.
