The first man-made plastic was created by Alexander Parkes who publicly demonstrated it at the 1862 Great International Exhibition in London. The material called Parkesine was an organic material derived from cellulose that once heated could be moulded and retained its shape when cooled.

John Wesley Hyatt invented celluloid as a substitute for the ivory in billiard balls in 1868. He first tried using a natural substance called collodion after spilling a bottle of it and discovering that the material dried into a tough and flexible film. However, the material was not strong enough to be used as a billiard ball not until the addition of camphor which was taken from the laurel tree. The new celluloid could now be moulded with heat and pressure into a durable shape.

Besides billiard balls, celluloid became famous as the first flexible photographic film used for still photography and motion pictures. Hyatt created celluloid in a strip format for movie film. By 1900 movie film was an exploding market for celluloid.

After cellulose nitrate formaldehyde was the next product to advance the technology of plastic. Around 1897 efforts to manufacture white chalkboards led to casein plastics (milk protein mixed with formaldehyde) Galalith and Erinoid are two early tradename examples.

In 1899 Arthur Smith received British Patent 16,275 for "phenol-formaldehyde resins for use as an ebonite substitute in electrical insulation the first patent for processing a formaldehyde resin. However, in 1907 Leo Hendrik Baekeland improved phenol- formaldehyde reaction techniques and invented the first fully synthetic resin to become commercially successful with the trade name Bakelite. This was made using fossil fuels.
