天然花岗岩与人造岩的差别

天然花岗岩与人造岩的差别

这里所说的花岗石乃至石英粗面岩（即在火成岩中也算是含有氧化硅及氧化铝特别多而铁分子少的），都是以石英、长石为主，并含有若干云母及富于铁分（氧化铁）的黑绿或黑褐色的矿物。假若仔细观察这些岩石，便可看到许多像玻璃一般透明的颗粒和像瓷器一样鲜艳的白色或淡红色的颗粒。前者是石英、后者是长石。这四种岩石的化学成分虽然相同，但因为长石与石英等颗粒的大小不同，因而形成了不同的岩石。

Here of granite and quartz trachyte (that is, in the igneous rock is much contains silica and alumina and iron molecules less), are mainly quartz, feldspar, and contains a number of mica and rich in iron (iron oxide) dark green or dark brown mineral. If these rocks, careful observation, you can see a lot of transparent as glass particles and like porcelain, bright white or reddish granules. The former is quartz, the latter is feldspar. That four kinds of the chemical composition of rocks, while the same, but because of feldspar and quartz particles of different size, and thus formed the different rocks.

花岗岩全体是由比较大的颗粒（直径1~7毫米）构成的。石英粗面岩是在看不见颗粒的致密素地中有石英及长石的小粒存在。花岗斑岩及石英斑岩则介乎此二者之间，是在致密的素地内含有大粒的石英。这类岩石构造上的差异，主要在于由熔融的岩浆到冷固的时间长短，其中花岗岩最长，石英粗面岩最短，而花岗斑岩与石英斑岩则是在介乎两者间的时间内冷固的。陶瓷是以岩石作原料，而所以未能具有岩石般的颗粒，其主要原因是，陶瓷原料不像岩石那样在高温下完全熔化，同时所需要的冷固时间也较短，这是天然岩石与人造岩石即陶瓷间的最大区别。有时与石英粗面岩同样成分之物，以熔融状态流到地面上而骤然冷固，这样形成不含有像上述岩石那种用肉眼可见的石英、长石等颗粒，而形成全体一样的玻璃，即是所谓黑曜石和重晶石。由此可见岩石与陶瓷的本质相同，只有天工与人工的差别罢了。

Granite all is by the larger particles (1 ~ 7 mm in diameter). Quartz is trachyte in invisible particles dense grain to a small grains with quartz and feldspar. Granite porphyry and quartz porphyry is between the between the two, is the density of the element contains large grains of quartz. Such rock structure differences, mainly is by the molten lava to cold setting the length of time, including granite, longest shortest quartz trachyte, and granite porphyry and quartz porphyry is in between the time between cold setting. Ceramic is a rock as a raw material, and so fail to have a rock particles, the main reason is that ceramic material don't like rock completely melt at high temperature, the cold setting at the same time need time too short, it is a natural rock means the biggest difference between ceramic and artificial rocks. Sometimes with quartz trachyte similar ingredients, in a molten state flow to the ground and the sudden cold setting, this form does not contain visible with the naked eye like the rock quartz, feldspar and other particles, and form the same glass, which is the so-called obsidian and barite. So rock and the essence of the ceramic is the same, only the difference of the tico and artificial.

在花岗岩中含有二氧化硅特多的是半花岗岩和伟晶花岗岩。前者的长石与石英等的颗粒细小，后者则由特大的长石及石英的颗粒形成。其中有的在酿酒设备某部分集中了同样物质，而变成纯粹的石英脉，或纯粹的长石脉，也有的转变为半花岗岩（有些地方就用原来的半花岗岩作为陶瓷原料）。酱油陶瓷工艺基本知识2 釉的本质及成分

In contains silica of Trinidad and Tobago is aplite granite and white granite. Feldspar and quartz particles and small of the former, the latter is formed by particles of super-large of feldspar and quartz. In some concentrated in parts of the same material, and became pure quartz vein, or
