Abstract

"PROCESSO PARA REFINAR MASSA FUNDIDA DE VIDRO". Um processo para remover borbulhas (bolhas grandes em uma massa fundida de vidro) e grãos (bolhas pequenas em uma massa fundida de vidro) a partir de uma massa fundida de vidro por alimentação de bolhas de hélio (6) tendo um diâmetro entre cerca de 0,5 centímetro e cerca de 3 centímetros em uma vazão determinada e um local para produzir, eficazmente, um artigo substancialmente isento de bolhas.
