National Rubber Eraser Day

You can correct mistakes since 1770; National Rubber Eraser Day on April 15th celebrates the day the invention first began to make writing errors disappear.

History of National Rubber Eraser Day

Rubber (or wax) pellets were used to remove lead or charcoal stains on paper before rubber erasers. Another option for the eraser is crustless bread. A student said that Bread bleach is an alternative choice for rubber erasers, so they are available and no restriction. So we gave no thought to grabbing these and eating a solid portion to at least satisfy our hunger.

April 15, 1770 Joseph Priestly founded a vegetable gum to erase pencil marks. He named this substance "rubber".

1770, Edward Nairne developed the first rubber eraser on the market.

1839, Charles Goodyear discovered vulcanization (a method that cures rubber and turns it into a durable material). This method makes rubber bleaching popular.

1858, Hyman Lipman (Philadelphia, Pa.) patented a pencil with an eraser at the end.

We all make mistakes once or many times; however, thanks to the inventions of erase since many years ago, we can erase those mistakes.

Some interesting truths about National Rubber Eraser Day

In 1770, a manufacturer of scientific instruments named Edward Narine came across an eraser for rubbing pencil marks. He then sold his new as-yet-unnamed eraser for 3 shillings per half-inch square. On 3 April of the same year, Joseph Priestley, a British Separation Theologian, in his footnote mentioned this new material, its eradication properties, and its availability from Mr. .Edward. It was later named and identified as 'rubber'.

There is a chemical behind the eraser. When you write graphite from the pencil sticks to the fibrous material of the paper. If these pencil marks are rubbed, the eraser's polymer will stick more than the paper fibers, causing the graphite to stick to it.

Until 1770, breadcrumbs were used to remove graphite stains. They are softened, moistened and kneaded into balls. Although it is inexpensive and available in excess, it will rot over time.

The small erasers at the tip of the pencil are called "plugs", and the metal cups that withstand these plugs are called "iron tubes".

Small pink erasers attached to pencil tips contain volcanic ash, to increase abrasiveness.

Cap Eraser:

Usually available in pink and it can be inserted on top of a pencil. This kind of erasers is made of a mixture of Styrene Butadiene Rubber and a plasticizer and an abrasive to make it to stay at the tip of the pencil for a longer time.

Kneaded Eraser:

Kneaded Erasers is flexible, similar to soft clay and it can be pulled to a pointed tip. Artists use these erasers to rub off small details in pencil art, to reduce the intensity of shades from smaller areas, and to create a blurred effect in the drawing.

Unlike standard erasers, it does not remove pencil marks by dropping debris. Instead, it absorbs the graphite particles from the pencil mark and lightens the areas. An effective method to use this eraser is, stretch it like a thread, press it over the thinner areas of the pencil, after it has absorbed the graphite, and remove it from the paper. A new eraser is white and fresh with more benefits; gradually, it will turn into dark and lose its effect because of the absorption of black graphite.

Electric eraser:

These erasers work with battery and motor support. It looks like a pen and has a replaceable cylindrical rubber that is fixed to the motor shaft. Roll this eraser over the paper at a constant speed to erase the pencil marks, with little or no tearing of the paper.

Eraser pencil:

Half of this pencil is fixed with graphite, while the other half is attached with an eraser. Both sides of the pencil can be sharpened for sharp graphite (for writing) and a sharp eraser (for scrubbing).
