ABSTRACT:
The level of precious-metal inclusions in glass products, e.g., glass substrates for liquid crystal displays, is reduced by stirring molten glass in a stir chamber (11) under conditions such that the magnitude of the shear stress τ on the chamber's wall (19) and on the surfaces of the stirrer (13) is reduced while at the same time, the Q•E product for the system is kept high, where Q is the flow of glass through the stirring system and E is the system's stirring effectiveness.
