Sandblasting -- flat out -- is a misnomer.
Though silica sand was once the exclusive blasting abrasive, the potential health hazards of using sand far outweighed the cheap cost.
So while many first-time buyers expect to be pouring bags of sand into their blast machines, they are much more likely to end up blasting something along the lines of crushed glass or even walnut shells.
While it is a marvel alone to think people have actually made use of crushed glass and walnut shells, the subtle differences between blast media are truly attention-grabbing.
There is much more than you may have thought when deciding on a certain abrasive, or blast media. Some of the things you will inevitably consider: cost, biodegradability, shape, density, hardness, and mesh size. These attributes, though seemingly insignificant for particles so small in size, are extremely important when considering your application. To show you how the processes might be changed, here are five oddly satisfying gifs of users blasting away: all using different blast media suited to their application.
- 80 Grit Aluminum Oxide This long-lasting abrasive cuts through coatings and finishes and -- in spite of the increased cost is one of the most underused and underrated blast medias.
- Baking Soda
- Crushed Glass
- Walnut Shells
