What is smelt quartz?
"Smelt Quartz" is commonly sold as a variety of quartz, especially from many eBay vendors. "Smelt Quartz" is not quartz at all -- it is common glass, which is made from melting quartz in the presence another compound (called a flux) which lowers the melting temperature. Glass is not crystalline, whereas quartz and other minerals (with few exceptions) are crystalline. Most people can't tell the difference, but glass is optically isotropic (doesn't polarize light) whereas quartz is anisotropic (polarizes light). Glass also has a lower density, which you might be able to detect by its heft, and "smelt quartz" usually has unnatural looking streaky patches in it."
