Is sand the only media that is used in sandblasting?

So sandblasting is just a general term and oftentimes media other than sand is what is being used for the paint removal. Because of the silica in the sand it is common place to see other media is used instead of sand for health reasons and also because there are other media is out there that do a better job of cutting through the paint and into the work surface. Coal slag is one as well as garnet crushed glass Walnut shells and even bicarbonate of soda. Basically anything even slightly abrasive that you can shoot out of the end of a hose.
