详细说明:

塞伯坦发现硝化纤维的可塑性,并且,用它制造出来的东西还不透水。他饶有兴趣的用它制造了一些美丽的饭碗、杯子、瓶子和茶壶。他很赏识自己的这些创作,还特意写信给自己的好友著名科学家法拉第这个意外收成。可惜其时法拉第并未在意,直到一名拍摄师的呈现。拍摄师亚历山大·帕克斯有许多喜好,拍摄是其中之一。19世纪时,人们还不可以像今日这样购买现成的照相胶片和化学药品,有必要常常自己制造需求的东西。所以每个拍摄师一起也有必要是一个化学家。

He found the plasticity of nitrocellulose, and the thing made of it was still impermeable. He was interested in making some beautiful rice bowls, cups, bottles and teapots with it. He appreciated his works and wrote to his famous friend, Faraday, an accidental harvest. Unfortunately, Faraday did not care until the presentation of a photographer. Alexander Parkes, the photographer, has a lot of hobbies, and filming is one of them. In the nineteenth Century, people could not buy ready-made photographic films and chemicals like today, and it is necessary to often manufacture their own needs. So every photographer is also necessary to be a chemist.
