METHOD AND APPARATUS FOR DRAWING A LOW LIQUIDUS VISCOSITY GLASS

A method of a drawing a glass ribbon from molten glass sheet via a downdraw process by creating a temperature drop across a thickness of the molten glass flowing over forming surfaces of a forming wedge. The forming wedge includes an electrically conductive material for heating the glass above the r...
