Alexander Parks in Britain has many hobbies, and photography is one of them. In the19th century, people can't buy ready-made photographic films and chemicals as they do today, so they have to make what they need. So every photographer must also be a chemist. One of the materials used in photography is "collodion", which is a solution of "nitrocellulose". That is, the solution of nitrocellulose in ethanol and ether. At that time, it was used to stick photosensitive chemicals on glass and make photographic film equivalent to today. In the 1950s, Parks studied different methods of treating collodion. One day, he tried to mix collodion with camphor. To his surprise, after mixing, a flexible hard material was produced. Parks called it "paxson".
