Product Description:

Physical Characteristics

(1) with a brittle

(2) has a pyroelectric

(3) the refractive index of 1.533 ~ 1.541, 0.009 difference in birefringence dispersion 0.013

(4) has a strong piezoelectric quartz (Piezoelectric property), that is, will produce sparks when struck friction force, which is the method of flint to make fire.

(5) Common quartz inclusions are: the crystal (Hair crystal) - mainly rutile; grass into the crystal - mainly tourmaline; water bile crystal - liquid inclusions in quartz; green quartz - containing blue rutile needles; milk quartz - causes cloudy water from the fine pores; green quartz - by plate-shaped chlorite or debris may sometimes be green needles of actinolite; Aventurine (Aventurine) - quartzite green or reddish-brown interior contains fine mica sheets, also known as Yao quartz, commonly known as Aventurine. Frequently Smoke black to dark brown smoky quartz, mainly because these rocks contain large amounts of radioactivity have relations uranium, thorium elements.

Material property characteristics

1, scraping not spend

Quartz content of up to 94% of its quartz, quartz is the nature of natural mineral hardness only to diamond, high surface hardness of Ta Mok's hardness 7.5, much larger than the kitchen knife used shovels and other weapon, is not it scratch injuries.

2, do not pollute

Quartz is manufactured under vacuum Biaoliruyi, dense non-porous composite material quartz surface pH of the kitchen has an excellent corrosion resistance, daily use liquid substances do not penetrate the interior, long placed simply liquid surface clean and bright with water or other cleaning agents can be erased with a cloth that can be used to scrape the surface of the blade retentate when necessary.

3, with no old

Dan Guangze bright quartz surface is the result of more than 30 channels of complex polishing treatment process will not be scratching knife blade will not penetrate a liquid substance, no yellowing and discoloration and other problems, routine cleaning simply rinse with water can be, easy. Even after prolonged use, the surfaces like countertops with beautiful new clothes, no maintenance and upkeep.

4, fuel vain

Natural crystalline quartz is typically refractory, its melting point up to 1300 degrees, quartz completely flame made of 94% natural quartz, are not caused by exposure to high temperature combustion, but also with artificial stone countertops unmatched high temperature characteristics.

5, non-toxic and non-radiation

Quartz stone surface is smooth, flat and no scratches retention, dense non-porous material structure allows bacteria nowhere to hide, can be in direct contact with food, safe non-toxic!

Quality quartz crystallization using a selection of natural quartz mineral, its content of more than 99.9% SiO2 and miscellaneous manufacturing process to purify the raw material does not contain any heavy metal impurities may lead to radiation, 94% quartz crystals and other the resin additive makes quartz is no danger of radiation contamination.

Q:How do I set my Quartz clock's alarm?
melting point of quartz is so high that most ovens would melt first.
Q:Mining Quartz?
I wish I knew the answer on top of my head! I can immediately see so many applications to it. Since Quartz Composer can take in RSS feeds, I can imagine it can parse a more general type of XML equally well too! (maybe RSS is your alternative?) The first link is the developer discussion list for QC. Worse comes to worse, you might need to develop a custom patch with Objective-C, the second link is a comprehensive description of the Obj-C API for QC. Good luck!
Q:Those vases which are referred to as 'crystal', are they quartz or just glass.?

Q:I have a rock with quartz crystal formations in and on it. . Known as a vug(?).?
Use Snell's Law. If n1 is the index of refraction of air, n2 the index of refraction of quartz, θ1 the angle of incidence, and θ2 the angle of refraction, then n1 sinθ1 = n2 sin θ2. Now the index of refraction is n1 = 1. So sinθ1 = n2 sinθ2, and dividing both sides by sinθ2 gives n2 = sinθ1/sinθ2. Now θ1 = 27.0 and θ2 = 18.5. So n2 = sin27.0/sin18.5 = 1.43. So the index of refraction for the quartz is 1.43.
Q:Can a quartz crystal stone still be used for spellcraft?
Quartz is a mineral, perhaps because it has so many varieties you could think it a type of mineral. It can be crystalline, amorphous, and any color you can think of.
Q:Is this a quartz? Pics included.?
have not heard of the quartz crystal in specifics. even although I even have heard that granite is meant to have a impression on paranormal or non secular interest. maximum granites are composed of a extensive volume of quartz. additionally I even have heard of quartz crystals used to concentration energies.
Q:Quartz Crystal?
No. At the heart of the watch is the quartz crystal, which is a tuned oscillator. Essentially, a tuning fork. The crystal's frequency characteristic depends on the shape or 'cut' of the crystal. A tuning fork crystal is usually cut such that its frequency over temperature is a parabolic curve centered around 25 °C. This means that a tuning fork crystal oscillator will resonate close to its target frequency at room temperature, but will slow down when the temperature either increases or decreases from room temperature. A common parabolic coefficient for a 32 kHz tuning fork crystal is −0.04 ppm/°C². Thus, your watch will slow down with heat or cold.
Q:Quartz or granite countertops? Which is better?
Most all portable heaters are 750/1500 watts. Ceramic heaters have a fan to circulate the heat so you do hear the fan running. The ceramic heaters heat the air whereas the quartz heaters radiate heat much in the way you feel heat from sunlight. If your unit was totally quiet it didn't have a fan although some types do.
Q:How do Quartz Crystals grow in the wild?
Yes,It is more harder.
Q:Can a quartz watch running slow be sped up by keeping it in a warm (90 deg F) place when not worn?
Hi: Chemists use a technique known as hydrothermal crystallization: Some of the crystals which have been efficiently grown are emeralds, rubies, quartz, alexandrite and others. [1] The artificial xtls can be huge (a foot long?: check). Hope this helps. drp
