Has a book ever secretly been written with gold ink?

Accepted answer

This is very implausible, as related. Gold has a melting point of about 1065 degrees Celsius, so melting gold while out prospecting would be extremely difficult. Mixing something that hot with ink is just going to ruin the ink.

Looking at how inks were made before the modern chemical industry, the usual ways were to mix a very fine powder of pigment (fine soot, or iron sulphate and tannin) with a binder, such as hide glue, or gum arabic. Golden ink, as used in Tibet (thanks for those links) would have been made with very finely powdered gold.

Obviously, this prospector would not want to write in visibly golden ink, but mixing very fine gold powder with ordinary black ink would probably work. The difficulty would be creating that fine powder, with particles of about 0.001mm (about 1/20000th of an inch) in size, from a pretty ductile material, under field conditions.

The final problem is that the amount of gold you can hide this way is pretty small, but quite heavy. If you used up a bottle of ink, holding a fluid ounce, you could hide maybe 5-6 ounces of gold.

So, melting is thoroughly implausible, powdering and mixing with ink is more plausible, but quite unlikely.

At first, I tried to check the legitimacy of actually writing a book with golden ink, it seems there are numerous sources citing books that are actually written like this:

These books mention the use of golden ink inside other people's writings, and given how they were written already raises huge questions whether the scenario you sketched can actually be used to write an entire book in golden ink.

The main argument against it, it would weigh a lot.

Reading all the comments, I'd say this story is most likely implausable

  • The gold would weigh a lot and make the book extremely heavy.
  • Writing a book with it would mixing up actual ink and gold, the process of creating this would most certainly draw attention.
  • There are several other great alternatives to hide gold, so why make it harder for yourself to write it down when you can easily hide it in a cave? This way you can use it faster in case you'll have to ever trade it for food etc.
  • Extensive searching online hasn't brought up any reference to this.

I'd say this story is a fairytale.
