What Is Invisible Ink Good For?

[wiz9777]

First let me say I am new to fountain pens. I have been using for less than a year now. So pardon the silly question.

 

I was looking at a few inks online, and saw blacklight reactive invisible ink. Besides the kids writing secret notes, what do you do with it? I plan on ordering some just for the novelty of it, but I was looking for some ideas for its use.

Kids are not the only ones who want to write confidential things. You can use it to mark items of your property with a unique identifying mark too.

I presume your are speaking of Noodler's Blue Ghost (aka boom). It is a good ink for annotation in book.

 

You can also mark object (like book, wood...) with your driver license number for thief protection. I also use this ink for private annotation on a document I may need to photocopy. It won't show. You can also use that for counter signing an original. Basically, it is a security ink.

You can sit down and write a really nasty letter about your boss. Let the ink dry, then write something nice over it and send it to your boss. They will never know.

Also write rude messages or political commentary on banknotes.

Note it's not really invisible -- it can faintly be seen on some papers after writing.

Super secret spy notes!

If I write with invisible ink & my pen runs out of ink how will I know?

Careful--the reason Mata Hari was executed by a firing squad was her being caught in a hotel while in possession of invisible ink, just sayin'

I went through a divorce this past year and used it to keep notes and a journal. It was much more successful than the marriage. Now I use it to mark property and keep a calendar in my office so co-workers can't read it when they're in there. It's also a hoot to play with. I like to use it to put a Square and Compasses in the upper right corner of documents.

LOL, awesome suggestions! Thank you all. I think I will need to pass all cash under a blacklight from now on. I also love the Mason reference. LOL

There seems to be a lot of it about here on FPN.

I have a bottle of Noodler's Ghost Blue. It has been good for:

 

1.) Secret notes and drawings to myself in journal

2.) Mixing with regular ink and making regular ink that glows so that its sort of a "signature" of mine in ink.

3.) Smearing it on my face and clothing so I stand out when I go to a Club with black lighting

4.) smearing it on my wrist and making it look like they stamped me

Just a word of caution for all you secretive types:

From what I've read on here, Blue Ghost has had, for some, the inconvenient tendency of becoming visible after a period of time on certain papers (that is, it eventually becomes visible enough to be read easily without the aid of a blacklight).

 

Can anyone here comment on this phenomenon? Any experiences to share?

I have some writing in Blue Ghost written 3 years ago in a Paperblanks book. Still invisible unless a black light is used or you hold it up to a lamp.

I think that if one genuinely wants to keep a secret, there are far better ways than open text in Blue Ghost. UV lights are ubiquitous nowadays. Every store scans banknotes under them to determine if they are genuine. On some papers Blue Ghost is always vaguely visible. Blue Ghost can be used to discretely mark property. Some people I know like to use it for mischief, because they know that eventually a banknote will be scanned and a seditious message seen. Some people think it fun to misdirect and waste the time of lawful authorities with such messages. Some people think it fun to use it to play with conspiracy theorists in the same way.

I used blue ghost on white Rhodia paper, using a Lamy 1.1 italic nib. In areas where a lot of ink is accumulated, a faint greenish tint can be seen. After the Lamy, I used a noodles flex pen as a dip-pen, dipping it into the ink and then writing. Since the writing is finer in this method, it is harder to see the faint green tint.

 

That said, the faint tint becomes more difficult to detect with the naked eye if you use an off-white/ivory paper. In my ivory Rhodia webbiebook, the blue ghost is much more difficult to detect. I can still see a little something there, but that's because I know I wrote something there and I know what to look for. On the ivory Rhodia, it is 95% invisible without a special light.

[dizzymizzy]

My method is as follows: I use a thick, off white paper to write letters. I write in double-space. I write secret messages with blue ghost in the open spaces between the text. You'll need to be careful though, because if you write over a colored text with the blue ghost, the color may creep into a tiny area of the secret text. Just don't cross the streams and you'll be OK.

What is invisible ink good for? I use it to reply to anyone who posts 'odd' questions on here

I have some writing in Blue Ghost written 3 years ago in a Paperblanks book. Still invisible unless a black light is used or you hold it up to a lamp.

 

Hmmm...

I suppose that the book, or at least the page with BG, was left closed pretty consistently? I'm wondering if the, un-fading (for lack of a better term - sheesh! This must be the only ink where fading is one's least concern! Ha!), has anything to do with constant exposure to ordinary light (sunlight or lamps or whatever.)

How long ago did you write with it in the Rhodia? And, just to clarify, did you use the two different types of Rhodia? (stark white and 'ivory'?)

 

Lastly, and sorry for the incessant questions, but how old are your respective bottles of Blue Ghost, dadoody and dizzymizzy?

dadoody, yours is over 3 years, what about yours, dizzy?

 

I ask because I wonder if this 'un-fading' business has anything to do with from which batch-era the ink comes; Noodler's inks have been, at times, changed - and I believe that it was an aspect of the inks, at least earlier on (though it still perhaps occurs), that different batches of the same ink behaved or even looked slightly different to each other. Also, I wonder if you both keep your bottles in a dark/cool place?

 

Just don't cross the streams and you'll be OK.

Sound advice for any endeavour! However, I think you'll find that there is at least one situation where crossing the streams is, shall we say, a distinct necessity?

 

Just ask these guys:

Though, I suppose, that this happy fellow would tend to agree with you:
