摘要： A foamed glass article for preparing surfaces, the use therefor, and a method of making same are provided. The foamed glass article is in the form of a block, disk or similar product, and is used for preparing surfaces such as by sanding, rubbing and scraping the same to clean, abrade, polish, smooth, or the like such a surface. The foamed glass article is formed from a starting mixture that comprised waste glass, 0.10-20 % by weight of a non-sulfur based foaming agent, and optionally an additional abrasive material. A mixture of powdered waste glass and non-sulfur based foaming agent can be placed in a mold and heated so that the mixture sinters and subsequently foams. Thereafter, the foamed mixture is annealed.
