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 . . .

 

Sketching with Iron Gall Ink and Watercolor

Long before we had metal dip pens, artists drew with reed pens and with quills cut from the pinion feathers of a swan, turkey, or goose.  If you look at the ink sketches of artists such as Rembrandt or DaVinci, you will see some very common characteristics.  The ink lines vary in width – narrow, wide.  Often the ink is brown, and so those not in the know think that brown ink was a thing way back when.  In reality, it is the degradation of iron gall ink (aka oak gall ink) through time.  When initially laid down, it was black.  With time, it turns brown, and with a lot of time and depending on its degree of acidity, the iron gall ink can destroy the paper and drawing.

Over the past week, I have been playing with iron gall ink and a quill pen I cut from a turkey feather.  I have some homemade iron gall ink nearly done – come Thursday, it will be ostensibly ready to use.  Today, because I am finally at a point where I have time to play, I drew with iron gall ink and my quill, and then applied watercolors.  The ink took its sweet time drying, and I didn’t blow dry it, but let it air dry or blotted it to see what would happen.  As it is a damp day, it took awhile.  Anyway, the following three pictures were first done with the ink, dried, and then painted in with watercolor.  If you look at the pen strokes, you will see variations.  I’ve never drawn with a quill before, so it was a new experience, one quite different than with a dip pen or fountain pen.

The kumquats were the very first drawings I did with the quill and ink.  I had to really think about textures.  You see, when you use iron gall ink, it begins as a light grey, but as it is exposed to the air, it becomes darker and darker until it is black.  This made values a challenge!

Here, the ink in the picture was not quite dry, and some bled into the watercolors as I lay them down.

For the melons, the ink was taking forever to dry!  I decided to see what would happen if I blotted the ink.  The result was smudges, which you can see throughout the picture.

This final set was done with a sketchy watercolor.  No thought was really given to composition or to color as I wanted to use the ink to express outlines, shapes, and shadows.

Altogether, this was a lot of fun, and for me there is a potential I hadn’t really thought about in getting a sense of history by using historical tools – quills, iron gall ink – that were once the best technology had to offer.  I wonder what Rembrandt and DaVinci would think about paints in a tube, rather than the task of purchasing, grinding, and creating their own paints . . . perhaps they made their own quills and inks, too.

The Art of the Written Word

This past week or so has found me wandering into another element of water-based media:  Ink.

Ink is used in drawing, but it is also used in writing, whether using the Roman alphabet, Cyrillic, Arabic, Hebrew, Chinese, Japanese, or any other form of an alphabet for any one of the myriad of languages found throughout the world.

Making ink is an art, and that means knowing something of chemistry (no matter how simple) and permanency.  Ink is black and ink is colored – as are paints.  This past week has found me suddenly distracted by the making of iron gall ink, also known as oak gall ink, and cutting quills from feathers.  You can read about my adventures here, here and here for starters.  You can return to Ink, Yarn, and Beer for more updates, too, if you want.

Consequently, I have not had much time to paint or draw as I have been spending a lot of time reading about ink and quills in particular, as well as watching videos on the same.  This morning, I came across one which rather blew me away as it is global in nature, but local in artistry.  Huh – what does that mean?  Take 30 minutes of time to be quiet and to watch . . .

Chemistry Magick & A Quill Scraper

Early this morning, Josh and I went to the hardware store.  We bought supplies for Thursday’s indigo dyeing adventure and a piece of steel wire to make a quill scraper, a tool used to scrape out the membranes inside the feather’s quill, which is where it attaches to the bird.  Once home, Josh headed out to the garage, and within about 45 minutes produced a scraper, similar to the one found in yesterday’s quill cutting video with Mr. Ruud.  All told, it measures about 8″ in length and is a dandy little item.

Quill scraper made with a piece of steel wire, inserted into a wooden handle. End shaped and bent. Total length is about 8 inches / 40 cm. Works very well!

And then, a bit of housework – dusting! It’s gotta be done – a bit of lunch, a nap, and onto the magic of adding Ferrous Sulfate Heptahydrate to my slightly fermented jar of oak galls.

Ferrous Sulfate Heptahydrate was not hard to find.  I bought it from Amazon and had it within a day or so.  The jar is about 113 g. – I need 50 g. for the ink.  Thus, I weighed it out.

From here, it was time to add it to the oak gall mix, which has been out in the sometimes-sun since Saturday. I shook is multiple times everyday.

And now – oh, this was so exciting and beautiful! – the addition of the Ferrous Sulfate Heptahydrate to the oak gall mixture!

Ferrous Sulfate Heptahydrate as it settled into the oak gall and water mixture. So lovely!

And now, shaken up, the dark ink of the Iron Gall Ink!

And now, another 24 hours out in the sometimes-sun. Stay tuned for the addition of Gum Arabic (25 g) tomorrow!
