PREPARING GLASS COMPOSITIONS.

摘要

The present invention provides a method of preparing a ferrous iron-containing glass composition. The method comprises melting a batch of glass-forming components including an iron source and refining the resultant melt. The iron source comprises a fayalite-containing material. Glass may be produced having an increased ferrous content and an associated higher level of solar heat absorption with improved visible light transmission as a result of lower iron (III) content.
