Mermerit mi kuvars mı?​

Her ikisi mermer grubuna girmesine rağmen, her ikisi de doğal olarak oluşmasına rağmen, mermer taşı tam olarak doğal bir taş olarak kabul edilir. Kuvars ise; üretilirken %100’lük saflık derecesini koruyamadığı için yapay (kompozit) taş olarak kabul edilir.

Coante Çimstone mu?​

çimstone,belenko,calisco,coante quarst hammaddeli malzemelerdir. tezgahlar dünyadaki en sert minerallerden biri olan doğal kuvarstan yapılmaktadır. Kuvarsın bir diğer avantajı gözeneksiz olması sayesinde üzerinde bakterilerin çoğalmasına izin vermez ve lekelere karşı dirençlidir. Ailenizi korur ve temizlemesi kolaydır.
Such a clumsy word as ‘Querkluftertz’ could easily be condensed to ‘Querertz’ and then to ‘Quertz’, and eventually become ‘Quarz’ in German, ‘quarzum’ in Latin and ‘quartz’ in English.” Tomkeieff (1941, q.v.) noted that “quarz”, in its various spellings, was not used by other noted contemporary authors.
How can I identify Quartz on Mindat?
Quartz is one of the few minerals on Mindat where “visual identification” may be accepted as a method of identification for new locality entries and photos of well-formed crystals. In other cases, at least hardness should be checked, too. For quartz as a rock-forming mineral visual identification is often insufficient.
What is the difference between α-quartz and βquartz?
Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at 573 °C (846 K).

What is the history of quartz?​

Gradually, there were more references to quartz: E. Brown in 1685 and Johan Gottschalk Wallerius in 1747. In 1669, Nicolaus Steno (Niels Steensen) obliquely formulated the concept of the constancy of interfacial angles in the caption of an illustration of quartz crystals.
