Abstract
A furnace for melting batch materials, including, upstream in the direction of flow of the molten materials, a zone for introducing solid batch materials, and including a submerged burner and an overhead surface burner providing a flame that touches the surface of the glass at the point where the bubble from the submerged burner emerges. This association of an overhead, especially roof-mounted, burner and a submerged burner reduces the quantity of batch stones that may be sent toward the downstream end of the furnace.
