Ordinary glass is hard to break with ur penis but quartz glass u can stick it right through
Quartz agate would scratch glass. Glass would not scratch quartz agate.
"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."
I'm a bit curious as to who exactly calls it that; I've never heard that term before. At a guess I'd say it's probably because ordinary glass is somewhat opaque to certain frequencies of ultraviolet light, but quartz glass transmits it.
A quartz will display six sided prismatic crystal with a six sided pyramidal termination. The crystal system is referred to as hexagonal in most reference material, but may be described as trigonal in others.
No. Diamonds cut glass because diamonds are harder than glass. Quartz is not as hard as diamond.
Quartz agate would scratch glass. Glass would not scratch quartz agate.
well there really is know difference its just a beaker is a thiker kind of glass rather than ordinary glass!! ps if that helped please reply back:-)
Quartz and glassy silica are both composed of the same elements in the same proportion. The difference is that in quartz is crystalline whereas glass is amorphous. This means that in quartz, the atoms are all ligned up in a regular repeating lattice. In glass, the atoms are arranged in a random way. This is analagous to the difference between a set of childrens blocks that have been stacked up nicely in regular rows, and blocks that are just dumped in a heap, and are arranged randomly.

Glass is not a subset of quartz because glass does not fit the definition of a mineral in that it has no crystalline structure.
Heating a mixture of quartz (SiO2) and calcium oxide (CaO) - also known as lime, makes ordinary glass.
You will find quartz crystal being used in laboratory tubes and crucibles, ordinary glass, foundry molds and construction work, as a filter, crafted into a special lenses or prism and quartz glass tubes for lamps as well as in radios, televisions, radars and digital watches. Quartz is also a very important component of sandstone, quartzite and granite all of which are building stones.
Citrine is a form of quartz. Quartz will scratch glass.
Silica sand is the major component of glass (quartz).
