Q:what impurities give amethyst, rose quartz, and citrine their colors?

Fused quartz will handle the temperature; glass, even borosilicate glass, will probably not.

Q:Is it also located in outer space or just found on earth?and what causes it to have different colors?

Quartz crystals do not emit energy, so there is no scientific basis in your reaction. It is psychological.

Q:is there a fundamental difference between milky quartz, smoky quartz and rose quartz?

you got played

Q:whats the difference between the old omega seamaster professional quartz and the new automatic with blue thing you can twist ?? i know you cant buy the old one new anymore but i really want to know what the difference is thanks in advance

It can be ground out, with the proper abrasives.

Q:plz help me I am doing a project on quartz and it is due tommorow and i need to know those questions.PLZ HELP ME

It could be many things. Quartz often grows over other minerals. Do you have a picture you can post?

Q:like which crystallographic plane is the cut at?i know x,y,z is (100), (010) and (001) respectively. what is st?

Granite is a rock, not a mineral, composed of several minerals (mica, quartz,feldspar, etc.). Mica is a soft mineral which means it easily weathers, whereas quartz is one of the most sturdy minerals. Therefore, quartz would be the most resistant

Q:I am not sure if this is quartz. I don't know much about quartz but this rock I have is brittle and believed to be quartz and was found with many others that looks similar. I have been looking for a rock that I can start a fire with. If this is a quartz rock then what type of quartz is it?

All quartz makes fines weapons, thrown as chunks or splintered into sharp knives, spear and arrow tips. But irradiated, no. It is possible, of course, but no one does it. Smokey quartz is very common form of quartz, there is no commercial reason to treat it for sale.

Q:I am getting ready to remodel my kitchen and decided on Granite countertops. BUT, my friend told me that Granite can break (crack) very easy and I should consider Corian or Quartz. Any thoughts on helping me decide which to use? Thank you.

Quarts has a property of mechanical change with an electric current, likely it would just fracture. An electric arc could produce enough heat for melting. Do you have a clue how big a 50 KVA transformer is? You are talking as big as a truck trailer. Conductors would be like copper 4X4s Quarts is not a metal,it is a mineral and a crystalline mineral at that.

Q:We need to know this quickly. This is for a science fair project. We need to know all of the infomation you know about quartz crystals for this project. Thanks!

Yes. Quartz has a hardness of 7 on the Mohs scale, whereas corundum has a hardness of 9.

Q:quartz and glass are composed of same elements, what difference(s) allows quartz to scratch glass?

Area of each plate (A) = 6.5^2 cm^2 = 42.25 cm^2 = 0.004225 m^2 Dielectric constant of quartz (e) = 4.2 Permittivity of free space (e0) = 8.85 x 10^-12 F/m Distance between plates (d) = 2.0 mm = 0.002 m Capacitance = (e)(e0)(A/d) = (4.2)(8.85 x 10^-12)(0.004225/0.002) = 7.8522 x 10^ -11 F = (7.8522 x 10^-11)(10^12) pF = 78.522 pF
