Is it not so that the kneadable type eraser can be washed fairly to a 'clean as new' status. But what agent is best, e.g which will remove most leaving matrix fully in tact? Cisum.ili.dilm (talk) 00:01, 30 September 2009 (UTC)[reply]

"Another type of eraser is used specifically for marks on a chalkboard or whiteboard. Rather than being rubbery or gummy like pencil erasers, it is a hand-held wooden or plastic block with a dark felt pad on one side." - Types section. Does this really fit into this article? It seems to be more about the conventional artist's rubber/eraser. You can't really count a Board cleaner as a rubber/eraser in my opinion. I haven't taken any action since I'm unsure. There's no harm having it there, it just seems out of place.

According to Encyclopedia Britannica, "the first patent on an integral pencil and eraser was issued in the United States to Joseph Rechendorfer of New York City on March 30, 1858. (1)" Googling the name comes up with very few results, however. Britannica has been wrong before so shouldn't be accepted as definitive on this issue, but further research is definitely needed. Interestingly, most websites that mention Hyman Lipman also put the date he invented the pencil and eraser as March 30, 1858. Very odd.

I removed the following sentence from the history section, since it mostly repeats facts in the intro. It's well written though, so if someone wants to salvage it I only suggest they try to make it "aware" of what's in the intro.

Latex erasers are still known as 'rubbers' in England and Australia, causing occasional amusement to Americans, to whom a 'rubber', due to linguistic drift, is a latex condom.

Quick question that I can't seem to find an answer to - f the pink end of an eraser removes pencil marks (as is usual), what is the blue end used for? —Preceding unsigned comment added by Robyaw (talk • contribs)

I expect that the different colors are merely for looks, and that both ends of the eraser are used for erasing. --Ihope127 13:32, 7 June 2006 (UTC)[reply]

Actually most bi-colour rubbers I know of have a soft white end used for rubbing out pencil marks and a hard blue end usually used to erase pen marks 203.109.240.93 12:50, 26 April 2007 (UTC)[reply]

As an amature artist, I know the answer to this one. The purpose of the bi-color eraser is to provide two different textures of eraser. The hard and often gritted end is useful for erasing on heavy weights of paper or dark marks. The soft end is useful for light grades of paper which the hard gritted side would tear apart, and also for precision erasing, such as removing a light stray mark from among dark marks.--Scorpion451 03:22, 1 July 2007 (UTC)[reply]

Color

How come they are usually pink? --Colinstu 20:48, 12 March 2007 (UTC)[reply]

Actually I would say they're usually white... 203.109.240.93 12:50, 26 April 2007 (UTC)[reply]

Yeah, I don't remember having come across a pink one before. They're invariably white in my experience. Liam Markham 00:38, 13 May 2007 (UTC)[reply]

Well how do they color them then? lol Colinstu 23:22, 27 May 2007 (UTC)[reply]

I can clear up confusion here. In the US the traditional color for erasers is pink, which is the color of the rubber itself. In many regions, however, such as Europe, it is traditional for the rubber to be bleached before molding, making white. So it is not that they color them pink but that they bleach them white. Similarly in the US the two textured eraser is pink on the soft side and white on the gritted side, while in Europe they are most often white on the soft side and blue on the gritted , which is done with a powdered dye.--Scorpion451 03:22, 1 July 2007 (UTC)[reply]

I picked up an eraser from my desk drawer, and began to wonder how such a seemingly simple item could ever be conceived by man. After all, it is not like you see erasers laying around the prairie lands, or dangling from tree branches, and I've never personally seen one swimming around in some river or lake. It's often these complex simplicities that intrigue my imagination. So I began to transport my thoughts to a time before erasers. Human curiosity and desire for information is what led to the invention of writing utensils, this helped to integrate the accumulation of knowledge obtained from individuals and incorporate that into the broader spectrum of wanting minds. Well prior to the invention of erasers, anyone attempting to express themselves in the written form either had to be precise and completely eliminate errors, or cross them out. Then, as if by natural autotrophic correction, a man designed an item that will allow you to make a mistake, and just simply erase it! After I had finished delighting my imagination with this topic, I decided to see what Wikipedia had to say. Thanks for the info! —Preceding unsigned comment added by Daniel J Rice (talk • contribs) 16:23, 29 October 2007 (UTC)[reply]

My Opinion

Earsers are maybe the most inportant itmes in a man life. —Preceding unsigned comment added by 89.1.4.121(talk) 11:01, 17 May 2008 (UTC)[reply]

Question

I was wondering... How come, say a cheap pencil's eraser is hard and practically useless, but then you get a Ticonderoga brand pencil and it erases flawlessly? Perhaps that info should be located somewhere?
