Abstract
La presente invención se refiere a mejoras a método para fabricar vidrio, para controlar el estado de valencia final de iones multivalentes contenidos en el vidrio, que comprende: derretir los materiales de carga de vidrio conteniéndo una fuerte de ion multivalente y un agente de refinamiento en una zona corriente arriba en la cual las condiciones redox en el vidrio derretido se mantienen relativamente oxidizantes según se mide por la proporción de hierro ferroso a hierro total, por lo que el material de carga es substancialmente licuado mientras que se evita una desasociación prematura indebida del agente de refinamiento y se asegura la presencias de un agente de refinamiento en el vidrio derretido que entra en una zona de refinamiento corriente abajo para proporcionar un refinamiento adecuado; en una zona corriente abajo introducir un agente reductor uniformemente a través del derretido para alterar las condiciones redox para ser mas reductor según se mide por un aumento en la proporción de hierro ferroso a hierro total de por lo menos veinte por ciento en comparación a la proporción en la zona corriente arriba, reduciéndo por tanto la solubilidad del agente de refinamiento en el derretido para inducir la desasociación de el agente de refinamiento para así ayudar en el refinamiento, y controlar por tanto el estado de valencia final de los iones multivalentes en el producto de vidrio mediante el inducir una proporción mayor de iones multivalentes que van a estar presentes en su estado de valencia mas bajo.
