Abstract
Un método para producir artículos de vidrio a partir de una preforma de vidrio tubular que tiene en toda su masa un retículo de poros interconectados y una composición que es sustancialmente uniforme que imparte a dicha masa un índice de refracción sustancialmente uniforme, modificando el índice de refracción de dicha masa de tal manera que el índice de refracción en la porción exterior de la misma es menor que en su porción interior, y consolidando la preforma para formar una masa de vidrio denso tubular que tiene un índice de refracción en gradiente, caracterizado por el hecho de que dicha masa se seca y simultáneamente sufre una modificación en su índice de refracción concomitante a dicha etapa de consolidación.
