Abstract
A method of controlling defects in a glass product produced in a tin bath furnace includes measuring at least one parameter of an atmosphere associated with the tin bath furnace, wherein the parameter is selected from the group consisting of dew point and density, correlating the measured parameter with defects in the glass product, and controlling the measured parameter in a direction corresponding to decreased defects in the glass product by controlling a flow rate of a process gas relative to the furnace wherein the process gas includes one or more of hydrogen and nitrogen.
