We see it constantly: it fills our stores and our bins, our waterways and nature spaces, our households and workplaces. But did you know that some early plastics were actually created in an effort towards conservation?
The word ‘plastic’ initially referred to a state of being malleable or pliable, and it wasn’t until quite recently that it became synonymous with a category of materials called polymers. Polymers consist of long chains of molecules and can occur in nature, but over the last two centuries people have learnt to create synthetic versions out of things like plants and petroleum.
Up until the 19th century people were limited in their creations by the natural materials available, using things like wood, metal and bone for a significant portion of our products. For example, billiard balls were always made from elephant ivory. However, the rising demand for billiard balls meant that elephant ivory became increasing scarce and price increased dramatically, which left producers scrambling. There was a sudden awareness of the limits of continually harvesting natural resources, but no clear alternative to use in its place.
In 1864, an American company called Phelan & Collender announced a challenge to the public: create a substitute for ivory that could be used to create their new billiard balls, and you could win $10,000. “The material or composition of the artificial ivory must possess the qualities of elasticity, density and hardness,…[be]… easily turned of a perfect spherical form in the lathe,… readily colored and polished. It must not shrink, warp, or crack under ordinary variations of atmospheric temperature. Its specific gravity must be equal to that of natural ivory,… Its cost…must be at least fifty per cent less”
Enter stage right, John Wesley Hyatt, a printer from Albany in the state of New York. Hyatt decided to try his hand at this seemingly impossible challenge, and so celluloid was born. Made of cellulose nitrate, camphor and ground cow bone, the new and improved material was a hit! Hyatt was business savvy, and decided to patent his design in 1869 and start his own company, rather than accepting the reward and signing his design away. Today, celluloid is regarded as a significant innovation in the history of plastic objects. There was just one hitch: celluloid is an extremely flammable material.
In use as billiard balls, as Hyatt himself once observed, “occasionally the violent contact of the balls would produce a mild explosion like a percussion guncap. We had a letter from a billiard saloon proprietor in Colorado, mentioning this fact and saying he did not care so much about it, but that instantly every man in the room pulled a gun.”
This non-descript, tired-looking badge from our Bendigo assemblage (pictured) was identified by our team as being made of celluloid. It shows just how diverse the uses of this material were, and reminds us to never underestimate the story behind an object, even if it looks plain on the outside!
