Media – Crushed Glass

What is Crushed Glass?  And What is it Used for?

Crushed bottle glass (ESCA Glass) blasting media is an engineered “sandblasting” media manufactured from 100% recycled bottle glass. Crushed glass is a good general purpose abrasive and is approved for use in numerous federal and state government agencies, and military branches. ESCA bottle glass works great in slurry systems, vapor, dustless, and dry-blast equipment.

How can Crushed Glass be Silica-free?

Recycled bottle glass is chemically known as Amorphous Silica. Free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting medias. Silica-sand dust in its natural state has an “open” crystalline structure that has the capability of sticking to lung tissues. When this happens, the likelihood of developing a serious respiratory disease called Silicosis increases. Because our recycled glass blast media is amorphous, its crystalline structure is “closed”, which makes it impossible to physically stick to human lung tissue. When a person is exposed to amorphous glass fines or dust, the body will expel the dust as it would any other type of natural dirt. Benefits of Glass Blasting In addition to worker safety benefits, crushed glass delivers a natural, whiter metal finish than many other sandblasting abrasives, and significantly decreases embedment issues—up to 5 times less than slag blast media.

Crushed Glass & Dust

Crushed glass is an eco and operator-friendly blasting media that eliminates the health risk of airborne carcinogens. It is non-hazardous, non-toxic and completely inert, so is safe to use around water.  Glass dust is classified by OSHA/NIOSH as only “nuisance” dust because it contains less than 1% free silica. Glass also does not contain virtually any of the OSHA identified Heavy/Toxic Metals associated with slags and some other mineral abrasives like natural olivine. Lastly, since glass is translucent, visibility and productivity are significantly improved when compared to a blast environment using traditional hard abrasives.

The Benefits of Using Crushed Recycled Bottle Glass

Glass works great for removing typical coatings and other surface preparation applications. Glass is versatile, and can be used as a dry blasting media or combined with water for use in slurry blasting machines. SAVE MONEY TOO! Crushed glass is less dense than other sandblasting medias. This means greater productivity due to more blast time between pot refills AND less material will be used, which reduces both disposal and media costs. Our crushed glass comes in four different mesh sizes to suit your blasting needs.

In Search of a Media Harder than Glass?  We Can Help!

We also offer JET MAG, which is a harder, more aggressive abrasive and is better suited for traditional sandblasting.  JET MAG is a direct replacement for Black Beauty, Coal Slag, and Silica Sand
