Abstract

Se describe un metodo de afinado de vidrio que incluye hacer fluir un bano de vidrio fundido (22) a traves de una camara de afinado (20, 420). El bano de vidrio fundido (22) tiene una subcorriente (62) que fluye por debajo de un desnatador (50, 250, 350, 481, 589) que esta parcialmente sumergido en el bano de vidrio fundido (22). Uno o mas agentes de afinado se introducen en la subcorriente (62) del bano de vidrio fundido (22) directamente debajo del desnatador (50, 250, 350, 481, 589) de un componente de material de afinado soluble (68, 268, 368, 468 ). De esta manera, el (los) agente(s) de afinado pueden apuntar selectivamente a las burbujas de gas (88) llevadas debajo del desnatador (50, 250, 350, 481, 589) dentro de la subcorriente (62) del vidrio fundido (22) para su eliminacion. El metodo puede emplearse para refinar vidrio fundido producido en un fundidor de combustion sumergida (14). Tambien se describe un recipiente de afinado (10) para afinar vidrio fundido.
