A method of treating a surface to remove unwanted material therefrom, including providing a foamed glass article formed from a starting mixture including glass, a carbonate foaming agent, and a devitrification agent selected from the group potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof, and contacting the surface with the foamed glass article while providing relative movement between the surface and the article. The crystal silica content of the foamed glass body is less than 1 weight percent. The surface is treated by sanding, rubbing, scraping, degreasing, polishing, cleaning, smoothing, depilling, grooming, stripping, degumming, and combinations thereof. The surface is selected from the group comprising wood, metal, plastic, fiberglass, porcelain, glass, enameled surfaces, ceramic, concrete, or tile, and belongs to a member of the group comprising pools, spas, griddles, grills, fryers, bottles, glassware, cement pieces, marble, granite, monuments, skin, animal hides, textiles, garments.

1. An article for treating a surface, comprising a foamed glass, the foamed glass formed from a starting mixture comprising between 1 and 2 weight percent carbonate foaming agent, between about 5 and 20 percent by weight devitrification inhibitor, with the balance being glass; wherein the foamed gla
1. An article for treating a surface, comprising a foamed glass, the foamed glass formed from a starting mixture comprising between 1 and 2 weight percent carbonate foaming agent, between about 5 and 20 percent by weight devitrification inhibitor, with the balance being glass; wherein the foamed glass is free of crystalline silica, wherein the devitrification inhibitor is selected from the group comprising potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof. 2. The article of claim 1 wherein the surface to be treated is selected from the group comprising wood, metal, plastic, fiberglass, porcelain, glass, enameled surfaces, ceramic, concrete, or tile. 3. A body for treating a surface and comprising a foamed glass, the foamed glass formed from a starting mixture comprising between 1 and 2 weight percent carbonate foaming agent, between 5 and 20 weight percent devitrification inhibitor, with the balance being powdered glass; wherein the foamed glass is free of crystalline silica, and wherein the devitrification inhibitor is selected from the group comprising potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof. 4. The article of claim 1 wherein the foaming agent is selected from the group including barium carbonate, calcium carbonate, magnesium carbonate, sodium carbonate, silicon carbonate, and mixtures thereof. 5. The article of claim 1 wherein the devitrification inhibitor is present in amounts of between about 5 weight percent and about 10 weight percent.
