Abstract

processo de fabricação de vidro. em um processo de fabricação de vidro, uma mistura de materiais formadores de vidro sólidos (18) pode ser fundida por aplicação de calor de um ou mais queimadores de combustão submersos (34) para produzir um volume de vidro fundido não refinado compreendendo, em volume, 20% até 40% de bolhas de gás. um agente de refino pode ser introduzido no vidro fundido não refinado para promover a remoção das bolhas de gás do vidro fundido. o vidro fundido não refinado incluindo o agente de refino pode ser aquecido a uma temperatura na faixa de 1200°c a 1500°c para produzir um volume de vidro fundido refinado. o vidro fundido refinado pode compreender, em volume, menos bolhas de gás do que o vidro fundido não refinado. um material corante pode ser introduzido no vidro fundido refinado para produzir um volume de vidro fundido com uma cor final desejada.
