Abstract
A method of producing flint glass using submerged combustion melting involves introducing a vitrifiable feed material into a glass melt contained within a submerged combustion melter. The vitrifiable feed material is formulated to provide the glass melt with a glass chemical composition suitable for producing flint glass articles. To that end, the glass melt comprises a total iron content expressed as FeOin an amount ranging from 0.04 wt % to 0.06 wt % and also has a redox ratio that ranges from 0.1 to 0.4, and the vitrifiable feed material further includes between 0.008 wt % and 0.016 wt % of selenium or between 0.1 wt % and 0.2 wt % of manganese oxide in order to achieve an appropriate content of selenium or manganese oxide in the glass melt.
