摘要:摘要:本文主要讲述了宇宙大爆炸以来,天然玻璃的形成原因及过程。

起源、历史和保护玻璃
Origins, history, and preservation of glass


自宇宙大爆炸以来,天然玻璃已经存在形成的坩埚。天然玻璃时形成某些类型的岩石融化由于高温现象如火山喷发、雷击或陨石的影响,然后迅速冷却和固化。玻璃是由于陨石与地球表面的碰撞,被叫做陨石的玻璃或玻陨石。玻璃是由于雷击,被叫做电筒。电筒有各种各样巨大的形式和自然可以贴上自己的艺术品。然而,玻璃作为一个尚未开发的自然资源,在人类历史上很长时间不会离开。黑曜石是一种更常见的引用形式,用玻璃和古代玛雅和阿兹特克文明珠宝,更重要的是,被用来资助这些文明军队的优势。即便如此,在玻璃被发现和被引用之前。

在人类发展过程中,玻璃是最重大的事件之一,玻璃有很多罕见的特点:半透明,透明和无数的功能使用。它非常容易忽视个人的审美的过多,仪式,和其他功能。玻璃已经存在了超过五千年,其复杂和古代历史揭示了众多的审美可能性。一些技术已经完全消失了,而其他人则重新发现在人类历史的进程。古罗马历史学家普林尼,公元23-79年声称,腓尼基人在叙利亚商人运送石头实际上发现玻璃公元前5000年左右。普林尼告诉商家,坚实的基础,抵达后休息炊具在硝酸块放置火。

Natural glass has existed ever since the universe was formed in the crucible of the big bang. Naturally occurring glass is formed when certain types of rocks melt as a result of high-temperature phenomena such as volcanic eruptions, lightning strikes or the impact of meteorites, and then cool and solidify rapidly. Glass that is made as a result of the collision of a meteorite with the Earth's surface is called meteoritic glass or tektite. Glass that is made as a result of a lightning strike is called fulgurites. Fulgurites come in an immense variety of forms and can be labeled nature's own works of art. Glass, however, would not be left as an untapped natural resource for very long in human history. Obsidian is one of the more commonly Referenced forms of lightning-formed glass and was used by ancient Mayan and Aztec civilizations in jewelry, and more importantly, was used to grant an edge to these civilizations militaries. Even so, glass was discovered and referenced long before that.

The discovery of glass is among the most momentous occurrences throughout human development, glass has many uncommon characteristics: its translucence, transparency and its innumerable functional uses. It is extremely easy to overlook the aesthetic in light of the plethora of personal, ceremonial, and other capabilities. Glass has been around for over five-thousand years, and its complex and ancient history reveals a multitude of aesthetic possibilities. Some techniques have totally vanished, whereas others are rediscovered later in the course of human history. The ancient-Roman historian Pliny, CE 23-79, claimed that Phoenician merchants transporting stone actually discovered glass in Syria around 5000 BCE. Pliny tells how the merchants, after arriving to solid ground, rested cooking pots on blocks of nitrate placed by their fire. With the extreme heat of the fire, the blocks ultimately melted and mixed with the sand of the beach to create an opaque liquid (MacFarlane and Martin, 10). Glass created during this time had three major purposes: to glaze pottery, create jewelry, and to store liquids as containers. Around 500 BCE, these techniques spread to Asia and became known to the Chinese. Until then, the major technique of creating glass containers and jewelry was to use a system known as 'core-forming' (MacFarlane and Martin, 11).

Around 1650 BCE, with the introduction of the core-forming technique the production of small glass containers began. Core forming was one of the most widespread methods before the discovery of blown glass. This technique involved taking a core of organic materials, clay, sand, and manure in the shape of the vessel's interior.
