Glass grit or glass blasting media as it is often called performs as well, if not better in some cases than conventional shot blast abrasives.
Glass grit can produce a "white metal" finish which can be superior to other abrasives it can be used in volatile areas such as glass pipe lines, as there is no ‘cold sparking’ Low "rust-back" finishes can be produced by using glass grit Unlike other abrasives, glass does not contain significant chlorides or other salts which can accelerate the corrosion of cleaned surfaces Using glass grit can have the potential for lower dust generation than other abrasives during use.
Glass grit is also free from silicates and heavy metals meaning it is a safe product for the user with less dust generation, glass grit can leave less abrasive residues on cleaned surfaces thereby reducing post-blast cleanup costs and time Unlike many conventional blast abrasives like copper slag, recycled glass is classed as an inert and nonhazardous waste, this can significantly reduce the disposal costs.
