Alkaline earth silicates increase the flux: quartz ratio of any glass batch by replacing quartz. The flux:quartz ratio of any glass batch predicts the melting power or eutectic of a batch. An interesting technique that utilises this effect allows the glassmaker to employ particularly hard to melt formulas without hindering melting in the furnace.
