Abstract: The invention provides a low-cost energy-saving method of manufacturing a glass product directly from laminated glass waste without having to crush the glass and separate the plastic interlayer, even when the glass is cracked. The method comprises heating laminated glass to fuse the glass layers and broken pieces of glass into a glass product. The plastic interlayer initially acts as a binder to hold the glass pieces together, but is then burned out during the heating prior to fusing the glass pieces together. Fusing laminated glass with cracked glass produces unique textures and patterns in the glass product. Coatings can also be applied to produce different colors and patterns in the glass product.

Abstract: The invention provides a method to transform large quantities of fiber glass waste into useful ceramic products by a low-cost manufacturing process. The method consists of reducing the fiber glass waste into a glass powder; mixing the glass powder with additives into a glass-additives mixture; granulating the glass-additives mixture into granulated particles; forming the granulated particles into a green ceramic article; and heating the green ceramic article into the ceramic product. Water and clay can be included in the processing. 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.
