The first plastic, Parkesine, was made by Alexander Parkes in 1862. It was derived from cellulose, which could be heated and moulded, and was a cheap and colourful substitute for ivory or tortoiseshell. However, the first fully synthetic plastic was Bakelite, invented by Belgian-American chemist Leo Baekeland in 1907. Baekeland's plastic was patented in 1909 and was a game-changer due to its heat-resistant properties, electrical non-conductivity, and ability to be shaped into almost anything.

The first plastic patent was for Parkesine, created by Alexander Parkes in 1862
The first plastic patent was for Parkesine, created by Alexander Parkes and exhibited at the 1862 Great International Exhibition in London. Parkes was a metallurgist and inventor from Birmingham, England, who held at least 66 patents, mostly related to electroplating and the development of plastics. Parkesine was derived from cellulose and synthetic materials, and it could be moulded into various shapes when heated, retaining its form upon cooling. This invention addressed the growing environmental and economic concerns surrounding the use of animal-derived materials in industrial goods production, such as ivory in items like piano keys and billiard balls.
Parkesine was a significant milestone in the history of plastics, paving the way for future innovations. It was the first man-made plastic and a precursor to the development of other plastics. The creation of Parkesine demonstrated the potential for human manufacturing to transcend the limitations of nature. This breakthrough material sparked a shift towards synthetic polymers, which are now an integral part of our daily lives.
The quest for synthetic substitutes continued, driven by the need to replace natural materials in various applications. Belgian-American chemist Leo Baekeland invented Bakelite in 1907, the first fully synthetic plastic. Baekeland's invention, a combination of phenol and formaldehyde, revolutionised the market with its heat resistance, electrical non-conductivity, and mouldability. Bakelite's success attracted major chemical companies to invest in polymer research and development, accelerating the discovery of new plastics.
The story of plastic's evolution is a testament to human ingenuity and our relentless pursuit of innovative materials. From Parkesine to Bakelite, each advancement has shaped our world, for better or worse, and continues to influence our relationship with synthetic materials. The impact of these inventions extends beyond their practical applications, often reflecting and influencing societal values, environmental awareness, and consumer trends.

Parkesine was derived from cellulose and synthetic materials
Plastic is a word that originally meant "pliable and easily shaped". It is now used to describe a category of materials called polymers, which are made of long chains of molecules. Polymers abound in nature, and cellulose, the material that makes up the cell walls of plants, is a very common natural polymer.
In the mid-19th century, some animal-derived materials had become increasingly scarce due to industrialised goods production. This included ivory, which was used in items like piano keys and billiard balls, and tortoiseshell, which was used for combs. To tackle this environmental and economic problem, inventors began creating semi-synthetic materials based on natural substances.
One of the earliest of these was cellulose nitrate, which was patented by Birmingham-born artisan-cum-chemist Alexander Parkes in 1862 as Parkesine. Parkesine was derived from cellulose and synthetic materials. Specifically, it was made by dissolving nitrocellulose (a flammable nitric ester of cotton or wood cellulose) in solvents such as alcohol or wood naphtha and mixing in plasticizers such as vegetable oil or camphor. It was considered the first manufactured plastic and was a cheap and colourful substitute for ivory or tortoiseshell.
While Parkesine was a significant development, it was not a fully synthetic plastic as it still contained molecules found in nature. The first fully synthetic plastic was Bakelite, invented by Belgian-American chemist Leo Baekeland in 1907. Baekeland combined two chemicals, formaldehyde and phenol, under heat and pressure to create a material that could be shaped or moulded into almost anything. Bakelite sparked a consumer boom in affordable yet desirable products and was used for everything from radio and telephone casings to kitchenware, clocks, and jewellery.

It was the first thermoplastic, anticipating modern plastic uses
The first plastic, Parkesine, was made by Birmingham-born metallurgist and inventor Alexander Parkes in 1862. It was derived from cellulose, which could be heated and moulded, and it retained its shape when cooled. This material, exhibited at the 1862 Great International Exhibition in London, anticipated many modern uses of plastics.
Parkes' invention was a significant milestone as it was the first thermoplastic ever manufactured. It was an organic material derived from cellulose that could be crafted into a variety of shapes and made to imitate natural substances like tortoiseshell, horn, linen, and ivory. This was revolutionary as, for the first time, human manufacturing was not constrained by the limits of nature.
The development of Parkesine addressed the environmental and economic problems caused by the demand for ivory and tortoise shells. By the middle of the 19th century, some animal-derived materials had become increasingly scarce due to industrialised goods production. Elephants were facing extinction due to the demand for their ivory, which was used in items ranging from piano keys to billiard balls. Similarly, certain species of turtles were being pushed towards extinction as their shells were used for making combs.
Parkesine offered a solution to these issues by providing a cheap and colourful substitute for ivory and tortoiseshell. It demonstrated the potential for plastics to replace natural materials and laid the foundation for the development of modern plastic uses.
While Parkesine was a breakthrough, it was not fully synthetic as it was derived from a combination of natural cellulose and synthetic materials. The first fully synthetic plastic, Bakelite, was invented by Belgian-American chemist Leo Baekeland in 1907. Baekeland's invention combined two chemicals, formaldehyde and phenol, under heat and pressure. Bakelite was a game-changer due to its heat-resistant properties, electrical non-conductivity, and ability to be moulded into various shapes.

Baekeland's plastic was a game changer due to its heat resistance and mouldability
The first fully synthetic plastic was invented by Belgian-American chemist Leo Baekeland in 1907. He named his invention Bakelite, derived from the combination of two chemicals: formaldehyde and phenol, under heat and pressure. Baekeland's plastic was a game changer due to its heat resistance and mouldability.
Bakelite was a thermoset material, meaning it could be heated and moulded into any desired shape and would retain that shape once cooled, making it ideal for mass production. This property, combined with its durability and heat resistance, made it suitable for a wide range of applications, from radio and telephone casings to kitchenware, clocks, jewellery, toys, and even firearms.
The heat resistance of Bakelite was a significant advantage over previous materials. Its ability to withstand high temperatures without melting or deforming meant it could be used in applications where other materials would fail. For example, Bakelite could be used for kitchen utensils that needed to withstand the heat of a stove or oven.
The mouldability of Bakelite also set it apart from other materials. Unlike natural materials like wood or metal, which have inherent shapes and structures, Bakelite could be easily shaped into almost any form. This made it highly versatile, allowing manufacturers to create a wide range of products with complex shapes and designs that were previously difficult or impossible to achieve.
The combination of heat resistance and mouldability in Baekeland's plastic revolutionized manufacturing and product design. It sparked a consumer boom, with affordable yet desirable products reaching the masses. Bakelite's versatility and ease of production drove its popularity, and it became known as "the material of a thousand uses."
The impact of Baekeland's plastic extended beyond its contemporary applications. The development of this synthetic polymer marked a turning point in human manufacturing, freeing creators from the limitations of nature. Baekeland's success also attracted major chemical companies to invest in polymer research, leading to the discovery of numerous new plastics and shaping the course of modern materials science.
