Natural rubber was used as an eraser at least as early as 1770, but it was perishable and 'went bad' after a short time. Charles Goodyear developed the vulcanization process which made the kneaded eraser practical in 1839.
No.Latex is the main component in making an eraser.

I have always used a kneaded eraser, it takes a while to clean up an entire drawing, but it works.
well you can squish it squeeze or stretch it around or pull it apart and put it back together, but it takes a long time.
Try "erasing" an eraser on a wooden table. Smush them together, and keep it going till it gets bigger. You are basically making an eraser 'ball" This eraser "ball" is basically a kneaded eraser.
Wheat gluten, when kneaded, forms an elastic structure that had the unique ability to trap the carbon dioxide given off by the yeast
Kneaded erasers don't wash well, at least I've never had much luck doing it. They are however fairly inexpensive, so I tend to replace mine when they get too grubby to use. -- You can do that, or knead them and mess around with them until it starts getting cleaner. That's how you're supposed to clean them. ~Xxlifedistortionxx
The homophone for "needed" is "kneaded".
You can't make the perfect kneaded eraser that you find in stores, but if in any case your kneadable eraser is all messed up, you can use a substitute one by using just a slice of bread! Here's how; Take a slice of bread. Roll it until it's very tight. Make sure it doesn't break! Unroll it. Roll it again. Create a sharp point out of it, make the point short or the bread's gonna break. Use it! This technique may not work for long, but can be used for a day or two until you'll need a new slice of bread! Be sure to buy a proper kneaded eraser though, they work better and are pretty cheap!
Kneaded Erasers are most effective with charcoal and soft pastels. As charcoal or pastel dust build up on the eraser's surface, it can be kneaded to produce a fresh working surface. This type of eraser can also be plied into various shapes and used as a drawing tool to make highlights on charcoal, pastel, and pencil drawings. is this what u were talking about? They are called "Blending Tortillons."
