What that you must know about glitter
It’s old. Very, very old.
I assumed that glitter was invented some time within the Victorian period, probably for the only real purpose of gaudying-up sentimental greeting cards. But glitter is far older than I ever guessed.
Some time round 40,000 B.C., historic people started dusting sparkly crushed minerals over their cave paintings. As early as the sixth century A.D., Mayans had been adding glitter made of mica to their temple partitions, based on National Geographic. And in 2010, the BBC reported that reflective materials was discovered blended in with what is believed to be the residue of 50,000-yr-old Neanderthal cosmetics.
It’s not made of metal.
Aluminum, perhaps tin: That’s what I assumed glitter was made of. Nope. Fashionable glitter was invented in 1934 in New Jersey, of all places, when American machinist Henry Ruschmann figured out a technique to grind plastic into glitter. Eventually the raw materials developed into polyester film layered with coloring and reflective materials "fed by means of a rotary knife cutting system … form of a mix of a paper shredder and a wood chipper," according to glitter manufacturer Joe Coburn. Before that, glitter was made of glass. Not something you’d wish to eat.
Tons of glitter are produced every year (literally, tons). There are 20,000 types of glitter available from pioneer glitter-makers Meadowbrook Innovations alone, ranging from the run-of-the-mill craft glitter you keep in mind from kindergarten to "particular effects" glitter for industrial applications. It may be as effective as mud or as chunky as confetti. As glitter manufacturer Coburn remarked on Reddit in 2014, an order of "2 tons a month is a really small measurement
You can see a glitter-making machine in action right here — it’s disturbingly environment friendly at reducing thin sheets of polyester film into gleaming little grains. Glitter isn’t biodegradable and most of the people don’t recycle it. So it’s not going anywhere.
You'll be able to eat it.
Hold on! You can’t eat just any glitter. It has to be edible glitter, a hip new condiment that gained fame on Instagram in 2017. Since the first twinkling photographs showed up, it’s made an appearance on everything from donuts to bagels to pizza.
In the interest of serious academic analysis, I imagine it’s essential that I investigate and devour edible glitter. What is it made of? When was it invented? Most essential of all, what would occur if someone baked it into a cake and ate it?
