剑桥雅思12 Test8 Passage1阅读原文翻译


From our earliest origins, man has been making use of glass. Historians have discovered that a type of natural glass — obsidian — formed in places such as the mouth of a volcano as a result of the intense heat of an eruption melting sand — was first used as tips for spears. Archaeologists have even found evidence of man-made glass which dates back to 4000 BC; this took the form of glazes used for coating stone beads. It was not until 1500 BC, however, that the first hollow glass container was made by covering a sand core with a layer of molten glass.



Glass blowing became the most common way to make glass containers from the first century BC. The glass made during this time was highly coloured due to the impurities of the raw material. In the first century AD, methods of creating colourless glass were developed, which was then tinted by the addition of colouring materials. The secret of glass making was taken across Europe by the Romans during this century. However, they guarded the skills and technology required to make glass very closely, and it was not until their empire collapsed in 476 AD that glass-making knowledge became widespread throughout Europe and the Middle East. From the 10th century onwards, the Venetians gained a reputation for technical skill and artistic ability in the making of glass bottles, and many of the city’s craftsmen left Italy to set up glassworks throughout Europe.



A major milestone in the history of glass occurred with the invention of lead crystal glass by the English glass manufacturer George Ravenscroft (1632—1688). He attempted to counter the effect of clouding that sometimes occurred in blown glass by introducing lead to the raw materials used in the process. The new glass he created was softer and easier to decorate, and had a higher refractive index, adding to its brilliance and beauty, and it proved invaluable to the optical industry. It is thanks to Ravenscroft’s invention that optical lenses, astronomical telescopes, microscopes and the like became possible.

玻璃发展史上的一个重要里程碑是英国玻璃制造商George Ravenscroft (1632-1588)发明了铅水晶玻璃。为了消除在吹制玻璃中有时发生的雾化效应,他在该过程所使用的原材料中加入了铅。他制造的新玻璃更柔软,更容易装饰,并且有着更高的折射率,增加了玻璃本身的亮度和美感。这对于光学工业来说价值无限。正是由于Ravenscroft的发明,光学镜片、天文望远镜、显微镜和诸如此类的东西才成为可能。


In Britain, the modern glass industry only really started to develop after the repeal of the Excise Act in 1845. Before that time, heavy taxes had been placed on the amount of glass melted in a glasshouse, and were levied continuously from 1745 to 1845. Joseph Paxton’s Crystal Palace at London’s Great Exhibition of 1851 marked the beginning of glass as a material used in the building industry. This revolutionary new building encouraged the use of glass in public, domestic and horticultural architecture. Glass manufacturing techniques also improved with the advancement of science and the development of better technology.

在英国,现代玻璃产业直到1845年废除消费税法之后才开始真正起步。在这之前,玻璃作坊中所融化的玻璃被征以重税,而且这一税收在1745年到1845年之间被持续收取。Joseph Paxton为1851年伦敦世界博览会所设计的水晶宫殿标志着玻璃开始作为一种材料被应用于建筑工业中。这一革命性的新建筑鼓励在人们在公共、私人以及园艺建筑中使用玻璃。随着科学的进步和更好技术的出现,玻璃制作工业也有所提升。


From 1887 onwards, glass making developed from traditional mouth-blowing to a semi-automatic process, after factory-owner HM Ashley introduced a machine capable of producing 200 bottles per hour in Castleford, Yorkshire, England — more than three times quicker than any previous production method. Then in 1907, the first fully automated machine was developed in the USA by Michael Owens — founder of the Owens Bottle Machine Company (later the major manufacturers Owens- Illinois) — and installed in its factory. Owens’ invention could produce an impressive 2,500 bottles per hour. Other developments followed rapidly, but it was not until the First World War, when Britain became cut off from essential glass suppliers, that glass became part of the scientific sector. Previous to this, glass had been seen as a craft rather than a precise science.

从1887年开始,玻璃制作从传统的人工吹制进化到半自动流程。当时的工厂主HM Ashley在英格兰约克郡的Castleford引进了一台每小时可以生产出200个瓶子的机器。这比之前任何生产方法都快了不止3倍。随后,1907年,美国的Michael Owens(Owens Bottle Machine Company的创始人,即后来的大型制造商Owens-Illinois)开发出第一台全自动机器,并将它安装在自己的工厂里。Owens的发明可以每小时制造出令人惊叹的2500个瓶子。其他的进展很快跟上。但直到第一次世界大战,英国失去其主要的玻璃供应商,玻璃才成为科学研究的一部分。在此之前,玻璃被当作是手工艺品,而非精确的科学。


Today, glass making is big business. It has become a modern, hi-tech industry operating in a fiercely competitive global market where quality, design and service levels are critical to maintaining market share. Modern glass plants are capable of making millions of glass containers a day in many different colours, with green, brown and clear remaining the most popular. Few of us can imagine modern life without glass. It features in almost every aspect of our lives — in our homes, our cars and whenever we sit down to eat or drink. Glass packaging is used for many products, many beverages are sold in glass, as are numerous foodstuffs, as well as medicines and cosmetics.



Glass is an ideal material for recycling, and with growing consumer concern for green issues, glass bottles and jars are becoming ever more popular. Glass recycling is good news for the environment. It saves used glass containers being sent to landfillAs less energy is needed to melt recycled glass than to melt down raw materials, this also saves fuel and production costs. Recycling also reduces the need for raw materials to be quarried, thus saving precious resources.
