1. A method for making a ceramic product from waste glass, comprising:
- heating a solid organic binder to form a liquid organic binder;
mixing the waste glass with the liquid organic binder to form a liquid-binder-coated glass mixture;
cooling the liquid-binder-coated-glass mixture to form a solid-binder-coated-glass mixture;
forming the solid-binder-coated-glass mixture into a green ceramic article;
heating the green ceramic article to burnout the organic binder; and
firing the green ceramic article to sinter the green ceramic article into the ceramic product.

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.
