The sand or the recycled glass is melted, typically with soda ash, so the melting point is lowered. Lowering the melting point improves the efficiency of the flat glass manufacturing process because it means that less heat is required to melt the sand. While the sand is being melted, other additives can be added alongside the soda ash.
