Gum Arabic - binders for inks
- 20 g resin tubers
- organic material from the resin of shrubs
One has to cut an angle downward into the bark and the leaking milk juice makes a drop with a diameter of 2-7 cm. This juice is collected, dried and crushed.
Production of iron Gallus ink
1. the Oak gallus apples (50 g) are boiled in 500 ml of water.
2. we produce our ferrous sulphate using old nails or screws, and a bit of acetic acid.
3. as a binder, we add our Gum Arabic (20 g), mixed it in and ready is our ink.
How to produce our ferrous sulphate?
We put a few nails or screws in a box and mix it with vinegar and let it stand. Bubbles will rise up and work on the iron, until, after 3-4 days, the bubbles will die down. We then pour the fluid through a coffee filter, and our "ferrous sulfate" is ready. It can then be mixed with our broth made from Oak gall apples, and we add the Gum Arabic.
This ink is initially rather weak in colour, but the more it dries, the more it develops its colour. Eventually it darkens and becomes almost black due to the oxidation process. Please do not use your antique ink with a pen, but solely with our goose reeds or calami.
