工厂内部：铅笔Gregg Wallace在德国，是一家历史悠久的工厂，每天生产60万支铅笔。惊讶地发现，铅笔中的主要材料不是铅，而是石墨。他帮助将其与粘土混合以产生250公斤的批次?足以容纳200,000支铅笔。与此同时，Cherry Healey在曼彻斯特大学（Manchester University）研究石墨的惊人特性。她发现这种高导电性的碳还可以承受高达3,000摄氏度的温度。历史学家露丝·古德曼（Ruth Goodman）在湖区最早出现的铅笔的踪迹中。这是一个始于15世纪的故事，始于在Borrowdale山谷发现大量的纯石墨。雕刻成棍棒并用绳子包裹后，它成为了出色的书写工具。Ruth还想知道，在这个现代的数字时代，铅笔是过时的技术。但是她发现，表明笔迹死亡的文件在许多场合被过早宣布，可以追溯到印刷机的发明。Inside the Factory: Pencils Gregg Wallace is in Germany, at a historic factory which produces 600,000 pencils a day. At materials intake he is astonished that the main material in a pencil is not lead, but graphite. He helps mix this with clay to produce a 250-kilo batch – enough for 200,000 pencils.Meanwhile, Cherry Healey is at Manchester University examining the astonishing properties of graphite. She discovers that this highly conductive form of carbon is also able to withstand temperatures up to 3,000 degrees Celsius.Historian Ruth Goodman is on the trail of the very earliest pencils in the Lake District. It is a story which begins in the 15th century with the discovery of a huge deposit of pure graphite in the Borrowdale valley. Carved into sticks and wrapped in string, it made a brilliant writing tool.Ruth is also wondering if, in this modern digital age, the pencil is outdated technology. But she finds documents that show the death of handwriting has been prematurely announced on many occasions, dating right back to the invention of the printing press.
