Could a chemist reproduce inks of medieval quality, then apply them to vellum?

[Aga Tentakulus]

Did you know that for 20,000 years, right back to ancient times, the recipe hasn’t really changed at all?
Saliva/water, fruit juice/sugar and charcoal.

This refers to the cave painting.
The recipe for ink in ancient times was as follows:
Dissolve gum arabic in warm water, then add soot until it is a deep black.
This standard recipe was widespread as far afield as China.
It is not eaten by insects; it flakes off due to wear and tear. Half a million papyrus fragments bear witness to this. Work is currently underway to make them legible again.

And then came iron-based ink. It does not flake off, nor does it fade.
There are various recipes for this.
The cheapest is rusty red-brown. Water, rusty iron and a little salt. If you want it a bit redder, use red wine instead of water.
As I said, I’m working on it. To really understand it, you need to know everything.
For example: to make iron gall ink (grey-black) blacker, you add soot and gum arabic. If the soot flakes off, the grey is still visible.
