Documentation

Over the past week, I have been fermenting iron gall ink. Today I decanted the mixture, and here is my first attempt using it. I used a quill pen I cut from a turkey feather, and a dip pen using a flex nib. The paper is a Clairefontaine notebook with very smooth paper.

I am documenting this historical moment with some documentation . . .

Iron Gall Ink – A Quick Update

I spent most of the day dyeing with indigo on yarn . . . and some silk. A long day! But, on the list of things to do was to decant the iron gall ink I have been making over the past week.

Success! It is a really beautiful ink! It flows well off the flex dip pen nib as well as the quill I cut a few days ago. I’ll blog a bit more about it later, as at the end of a long day, I’m really tired, but really content with both the dyeing and the ink.

Kingfisher (Drawn with Iron Gall Ink)

This morning I did a quick sketch of a kingfisher using iron gall ink using a dip pen.  As you can see, there is a bit better variability in lines than when drawing is done with a quill pen (see yesterday’s post).  Both have qualities I really like – expressiveness, boldness, delicacy.  As I am used to using fountain pens, a dip pen is no problem once I learned how to control the amount of ink on nib.  What must be remembered is how to load the nib, and as nibs are all different, a bit of testing on scratch paper helps.

At present, I am deciding if I want to colorize this drawing – which is why for now, it is not!  If I do, I want to use very dilute but vibrant colors.  It is my hope that the ink will shine through the paint without my having to re-ink parts of it.

Gum Arabic – The Last Ingredient

Today is the final day for adding ingredients to the iron gall ink.  I added 25g. of gum arabic to the ferrous gallate (new name for the oak gall / ferrous sulfate heptahydrate solution) to create the final product of ink. Until the gum arabic is added, the solution is really just a solution or a liquid. My gum arabic was in a powdered form, so I simply placed it on top of the liquid in the jar, and shook it a lot. Since adding it, I am continuing to shake it. The gum arabic to the left is in its most common form – hardened sap. It has a jewel-like quality, I think – a lot like amber – and besides using it in ink, it is edible and has many uses in the food industry.

Gum arabic, the hardened sap of the acacia tree, is used a binder in ink, controlling the ink’s viscosity – how the ink flows.  It adds more control into the ink’s behavior, such as eliminating or lessening feathering, bleeding or cracking when use on paper or parchment. An element of luminosity or shine is another characteristic it imparts to ink.

In addition to controlling viscosity, gum arabic helps the ink to adhere to the paper. The water in the ink evaporates, and left behind is the colored portion of the ink; it is the gum arabic which acts as a glue to stick the ink’s pigment to the paper.

An ink – or watercolor paint or gouache – needs the gum arabic to give it the right consistency or body to flow easily, but not messily, from the pen or brush. Other pigmented inks may also crack, and the addition of the gum arabic helps prevent this; I don’t believe that iron gall inks suffer from cracking.

Soon enough, the ink and quill will be put to the test of actually using it!  Stay tuned . . .
