An example of the wonderful range of colours produced, and the corresponding materials used. The top one is the oak gall ink that was bought online, the remaining three were made by Fiona.
Learn how to make your own historical inks using foraged materials with this collaborative effort by Alan Bickley and Fiona Phipps.
Drawing with pen and ink is one of my favourite mediums, and at some future stage, I hope to get around to making my own inks in the traditional way.
After some discussion on the subject with Fiona, she also expressed a similar interest, and wasted no time in getting the ball rolling.
The process is not instant, it takes time and a degree of patience, but I truly believe that the results she achieved were well worth the effort involved!
I’ve been putting them to the test, and you can see exaples of both Fiona’s and my work below.
The influence of Rembrandt
After Rembrandt, Man Sitting in a Chair, A4 Two Rivers paper, Alan Bickley
I’ve recently been studying the line and wash drawings of Rembrandt, so I’ve based my sketches around his style - his exceptional drawings were made using a variety of the inks that were available to him during the 17th century - two of the most common at that time being bistre (made from wood soot), and oak gall ink, also referred to as iron gall ink.
I had intended to make the oak gall ink, but unfortunately it was too late in the oak tree cycle, so there weren’t any available for me to collect. I was still keen to try it, so I managed to source a small bottle online which had been made from oak gall’s collected the previous year.
But there were many more options readily available, namely acorn ink, oak leaf lichen ink, and old man’s beard lichen ink. It’s these last three that Fiona concentrated on, as the raw materials were readily available to her - all that was required was an enjoyable spot of foraging and a good deal of patience!

The history of ink
The first ever use of ink by man would have been cave paintings. The Chinese made and used inks in the 23rd century BC for writing, these inks were organic based, from plants and animals. Indian ink in the 4th century, was made from burnt bones, tar and pitch.
Then came the Romans who modernised the ingredients and methods of making ink. Ferrous sulphate inks came to the fore. By mixing ferrous sulphate with the tannin obtained from oak galls, it produced a black, long lasting ink for documents etc. including, I believe, the Magna Carta - this method hardly changed for the next millennia. However, using sulphate based inks had its drawbacks, as it faded, it corroded the parchment over time.
A selection of drawing and writing instruments that are suitable for using with ink
Inks will always be in fashion and have a strong following, particularly for the modern artist. They are adaptable and in their basic simplicity, beautiful and rewarding, whether using them to either draw or write with, calligraphy and script lettering in particular.
Acorn ink in its first stage of manufacture. Just look at that gorgeous colour already!
There is something very satisfying about foraging for the raw ingredients to produce sustainable art materials. Collecting fallen acorns and transforming them into inks that have been made the same way for centuries.
Each new batch will be unique with slight variations in colour, which all goes towards making your artwork original.
Ingredients & method following Fiona’s recipe
For my first batch of acorn ink, I used a small amount of the acorns that I’d collected, roughly about two average size cups, this amount made around 300ml of finished ink.
- Begin by rinsing the acorns to remove dirt and leaves, then fold them in a towel and break them up with a mallet or something similar.
After the acorns have been crushed and boiled
- Add the acorn pieces, including the fine bits and dust, into an old pan. Simply cover with water (preferably rain water), bring to the boil and simmer for around four to five hours, topping up to just cover the acorns as the water evaporates. The liquid will soon start to darken.
Straining the liquid into a glass jar
- When the liquid is the colour you require, or after the five hours, allow to cool then strain the liquid off into a glass jar.
This is where the alchemy comes in, to turn your lovely rich brown liquid into a black/grey ink! By adding an iron vinegar solution to your brown acorn liquid the colour is instantly changed.
- To make the Iron vinegar solution, add some rusty iron pieces in a jar - rusty nails, screws etc., even pieces of steel wool.
- Half fill the jar with white vinegar and put the lid on.
- This mix will soon change colour but leave for at least a week before straining it through a sieve and adding to your acorn ink.

- To take the ink to its final stage - to your cup of acorn liquid, add (up to) one tablespoon of the Iron vinegar solution. You can do this in stages depending on how black you want the finished ink. I wanted a dark grey to black rather than an Indian ink colour, so added a little at a time and tested regularly by dipping in a small piece of paper until I had the desired colour.
- To bind your finished mix add gum Arabic, a few drops at a time, until you reach a consistency that suits your needs.
- You don’t need to add a binder but you will find that the ink will sit on the paper rather than adhering to the paper, it also fixes the colour and makes it permanent.
- Store in small bottles which have a pipette included in the lid for easy use. I added a couple of cloves in the bottle to act as a preservative, they also tone down the smell of vinegar!

Oak leaf lichen ink & old man’s beard lichen ink
A variety of lichen that I collected, the Old Man’s Beard is the third one from the left
Ingredients & method following Fiona's recipe
Both the above inks are made in the same manner. You will require separate jars for each ink.There are no set quantity measurements to make this ink, it depends on the volume of how much of the fallen lichen you collect. I gathered a good large handful of each for my first batch and used the small jam jars to make it in.
Starting the process of making the lichen ink
- Break the lichen into small pieces and place in the jar. It is important to remember that making this ink requires a reaction that produces ‘orcein’ and requires oxygen, so you need to leave space between the mix and the lid, I left a third.
Add enough ammonia to cover the lichen (I used household ammonia) - It’s worth mentioning that ammonia should always be used in a well ventilated area, the smell and fumes can be overpowering!
- Leave the lichen to soak without a lid, in a well ventilated place, (I used the greenhouse) for about three days to a week.
- Stir the mix well every day to aerate. You will notice a change in the colour after about three days, if not before.
- The Oak Leaf Lichen will start to turn a pale pink to reddish colour and the Old Man’s Beard Lichen will turn a sepia colour.

- Once the mixture has been left and aerated, dilute with rain water. I worked on a two parts water to one part ammonia. In effect, I left a quarter of the jar with the original ammonia and lichen, added up to the three quarter level of the jar with rain water, and the final quarter of the jar I left for oxygen space.
- This stage is adaptable, it depends on the strength of colour you want your finished ink to be. You can leave this mix for anything from one month to three months, I chose to leave it for one month. Shake the jar daily and vent the top to keep the oxygen levels high.
- When you have the required colour, strain, add gum Arabic to your desired consistency, bottle, (don’t forget to add a clove) and label.
