Method for Reducing the Alkali Metal Oxide Content in Glass Melts

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a method for treating molten glass mixtures that contain silicon dioxide (SiO2) and alkali metal oxides, with the objective of reducing the proportion of alkali metal oxide in relation to silicon dioxide. This process specifically addresses how to lower unwanted alkali components in glass melts.
