“Is the dust caused from these dry grinding glass restoration companies dangerous?” Absolutely! The glass dust contains silica which is inhaled into the lungs and never leaves. In time, it creates difficulty breathing and can lead to lung failure and death. Please make sure that whatever company is performing any kind of glass grinding, scratched glass repair, glass graffiti removal, or glass resurfacing, they are now equipped for dust-free and will not introduce this harmful glass dust into your environment. For more information, read the Center for Disease Control article about silicosis and dry grinding.
