What is the best blast pressure for glass beading?
Between suction and pressure blasting, pressure is faster but again can create changes in the surface (if blast time or pressure is not well controlled). It is always a good idea to start at a low blast pressure and gradually increase to determine the blast pressure that is best suited for your needs. The maximum blast pressure for glass bead blasting is typically 80 psi for suction blast cabinets and up to 40 PSI for pressure blasting. Using these reference numbers you should be able to slowly determine the right blast pressure and time that will work well for your use.

Why is sand used in blasting?
Using traditional sand is how abrasive blasting got coined as sandblasting media, but it’s actually fallen out of favor in recent years due to one major reason: silica. Sand includes silica, which forms as dust when the sand erodes and poses a significant health hazard to those working with it. Silicosis is a deadly condition that affects people who breathe in these chemicals. Many countries have banned silica entirely, and the Occupational Safety and Health Administration (OSHA) has set limits on its usage. The measures you need to take for sandblasting media and using silica safely are extensive, so it is often much easier and more beneficial to use another blasting media that fits your application.
