Crystal Things To Know Before You Buy

其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。

Another enjoyment, and tasty, experiment is always to variety substantial crystals applying sugar. By heating sugar with drinking water then allowing this Alternative evaporate on sticks, you are able to type rock sweet from sugar crystals!

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正,浓度较高,内部无瑕为好。种类上紫晶最贵,其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

The ordered inner structure of huge crystals, such as fluorite and quartz shown listed here, is mirrored inside their geometric designs.

. These 4 constructions comprise almost all of the binary crystals with equal numbers of cations and anions.

, has the identical framework, but There are 2 selections for selecting the holes which the atoms will occupy. The 3rd layer might be put around the atoms of the primary layer, making an alternate layer sequence A

⑦、镀彩:运用类似电镀的手法在水晶表面以不同的色彩,层面较薄,经摩擦可划伤�?;出现划痕,由于镀彩经常位于底部,因此在镀彩底部经常采用其它对象附着,如生肖文镇。

市场上有很多人把熔炼水晶也叫做合成水晶,那是不准确的,一般都是以水晶废料为原料在高温高压下熔炼出来的,而不是结晶成的,不具备水晶的晶体特性,所以不能把熔炼水晶与合成水晶混为一谈;但是熔炼水晶耐高温,用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等,实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。

Crystals with clear flat faces are known as euhedral crystals, whilst those lacking defined faces are referred to as anhedral crystals. Crystals consisting of purchased arrays of atoms that are not generally periodic are identified as quasicrystals.

⑥、丝印:水晶表面附有不同的色料进行效果处理,颜色层面较厚,着力后方可脱落。

国家还并未给天然水晶提供一个等级划分的具体标准,水晶品种繁杂,每一品种都有他不同的评判标准。

压电性:水晶晶体受到压力时会产生电荷;反之,受到电压作用时,晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能,称压电性。
