Glass-based substrates including recycled content, and methods for producing the same

Abstract

Glass-based substrates including recycled content of highly crystalized cullet are disclosed. Also disclosed are methods for manufacturing a recycled glass-based material composition, the method comprising: melting a set of raw materials, the set of raw materials comprising glass-ceramic cullet. The glass-ceramic cullet comprising: a cullet composition comprising SiO2, Al2O3, and Li2O; greater than or equal to 70% by total weight cullet crystal phase. The melting is performed in a melting vessel held at a temperature, and for a time, sufficient to melt the glass-ceramic cullet to form a re-melted precursor material. The melted precursor material may be used to form a glass-based product which may be transparent or opaque.
