Plastics

Plastics is a product manufactured in a Chemical Factory. Petroleum is the material required to make it. It can be used as material for other products.
==History==
The basis for the development of plastics was celluloid. Since the 1830s and 40s, nitrocellulose had been obtained by treating paper, cotton or wood with nitric or sulfuric acid. The English inventor and metal specialist Alexander Parkes presented a synthetic material made of nitrocellulose at the London World Exhibition of 1862 and baptised it 'parkesine'. It was widely used in the production of such everyday objects as costume jewellery, cutlery handles, hair slides, boxes, etc. The American inventor Hyatt chose camphor as his main solvent in the 1870s and produced a tear-proof plastic that slowly replaced hard rubber and ivory.
==Did You Know That?==
The first synthetic materials were a sensation! Suddenly everybody wanted to have anything made of plastic. Dishes, cosmetics and toys made of colourful hard or soft plastic looked much jollier than other materials. In addition to this, they were very handy for home and work use as they were hygienic, washable, very light and indestructible. Who could resist such a boom? Wooden and metal objects were, at that time, considered old-fashioned. The plastic age had just begun.
