When is Rubber Eraser Day?

It's national rubber eraser day on the 15th April.

The Birth of the Rubber Eraser

In a world where mistakes are inevitable, the rubber eraser shines like a beacon of hope. But have you ever wondered how this marvelous creation came to be? Let's rewind the clock to the early 19th century, a time when writers and artists relied on primitive tools like bread crumbs and wax to erase their errors. Yes, you heard that right – bread and wax! Fortunately, in 1770, a British engineer named Edward Nairne revolutionized the world of erasing with the invention of the rubber eraser. Nairne crafted his erasers from natural rubber, a material known for its ability to effectively erase pencil marks without smudging or damaging the paper.

The Rise of the Rubber Eraser

As word of Nairne's creation spread, the demand for rubber erasers skyrocketed. Artists and writers rejoiced, no longer having to rely on unconventional methods to correct their mistakes. The rubber eraser became a staple in every pencil case, and its popularity only continued to grow with time.

A Twist in the Rubber Eraser Tale

Now, brace yourself for a twist in the tale of the rubber eraser. Did you know that the original rubber erasers were actually pink? Yes, it's true! In the early days, manufacturers added a dye to the rubber to give it a distinctive color. Over time, the pink hue became synonymous with erasers. It wasn't until the 20th century that white erasers, free from added color, started to emerge.
