You can get it back by throwing it in a freezer, at least I was able to when I should prove someone wrong... :-)

Here's[1] a proof I recorded a long time ago. Enjoy my notes on virtual memory.

Yea, but if you reuse the paper, it becomes an accidental palimpset with all the layers visible.

I had the same experience, still use them. Most ball point pens are not archival safe anyway, so to remove the guess work I scan my important stuff with my phone's camera anyway. It's my go to method for creating a graph for what I'm writing anyway.

But if I were in uni or something and were forced to maintain multiple projects at the same time(modules) I would probably opt for something else.

Ball point might not be safe for archival, but I can still read the stuff I wrote as a child 30 years ago; the stuff I wrote with fountain pen and its water soluble ink, not so much.

Lately I've grown super fond of "micro" liners, which are 0.3mm water-based ink pens. To me, their feeling when writing is awesome. BUT IT IS WATER BASED. So even a light rain can wreak havoc on my notes.

Ball-point pens don't feel the same, and the colors don't stand out as much to me. I've accepted the fact that water is a dangerous thing to my notes now.

> BUT IT IS WATER BASED. So even a light rain can wreak havoc on my notes.

Water based != water soluble when dry

I would suggest you try similar pens with a different ink. Staedtler Pigment Liner and Sakura Pigma Micron pens (both of which come in 0.3 mm) use water based pigments which are waterproof when dry and archival. They both survive rain quite well in my experience and are used for outlining by some artists who then apply water color paints or other water based media without the dried ink bleeding.

There are also waterproof fountain pen inks. Platinum Carbon and Noodler's Bulletproof Black are two good ones.

For a common counter example to a water based substance being water soluble once dry consider water based exterior latex paint.

Will look into them, thanks for the pointer :)

Unfortunately every pen of this kind I've used suffered from being water soluble after dry, so I just assumed all where.

Cold makes "erased" notes to appear, nothing disappears in reality.

You mean I can put my old, blanked out by sun, notes in the fridge and they will reappear ? If that works you made my day, sir !

Incredible indeed. Please update to let us know if it worked!

It worked ! I'll check if it stays dark but my notes have been restored ! Thanks !

So cool, thanks for sharing.

It worked for me (I was trying to prove someone else wrong.)

Freezer for sure.

Exactly. I tried erasable pens in elementary school and they were more problems than they were worth. Dead tree carcasses are unfortunately "cheaper" than losing work. :'(

Haven't tried it myself, but from what I've heard, putting the paper/notebook in the freezer should bring back the ereased stuff

Yup this works, I use Frixion pens and have done this. On the other hand, if you take your notebook out in freezing temps your erased writing might reappear!

For the original stated purpose of "whiteboarding", they're great. And like others stated, you can recover what you wrote if you really need to by cooling the paper past a certain threshold.
