Filed:

Jan 31, 2000

Appl. No.:

09/494968

Inventors:

Michael Joseph Haun - Santa Rosa CA 95409

International Classification:

C03C 1000

US Classification:

501155, 501 2, 501 5, 501 32, 65173, 651348, 65144

Abstract:

The invention provides a method to transform large quantities of waste glass into useful ceramic products by a low-cost manufacturing process. The major steps of the method consist of dry preparation of glass powder, granulation with a non-aqueous organic binder system, dry pressing with adequate green strength, and firing at low temperatures. Water and clay are not required in the processing, which eliminates problems that were encountered in the past. Only one firing step is needed with a low peak firing temperature of about 750Â C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products with only a small amount of porosity can be produced by the invention.

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.

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.

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.
