ABSTRACT:
The invention provides a method to transform large quantities of waste glass into useful ceramic products by a low-cost manufacturing process. The method improves green strength compared to previous methods, and does not require water or any other liquid solvent. Only one firing step is needed with a low peak firing temperature of about 700° C.to about 1000° C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products can be produced by the invention.
