How to Make Iron Gall Ink
First you need a recipe, conveniently we sell a kit that includes the following recipe
40 g of powdered Aleppo oak galls
25 g of iron (II) sulfate (with three drops of clove oil added to it)
25 g of gum Arabic
A pair of gloves
2 storage bottles
Coffee Filter/filter cloth
1 cup (120 mL) of water (distilled, or reverse osmosis filtered preferred)
¾ cup (180 mL) vinegar (white, cider, or wine)
¾ cup (180 mL) of wine (old is fine)
Note: Mix all ingredients with a plastic or stainless steel utensil (wooden utensils will be ruined). Wear Gloves through this entire process as the ink will stain your hands, clothes, etc.
Well, let’s go through this a step at a time.
You need to gather all of your materials, to get oak galls, iron(II) sulfate, and gum Arabic, I recommend buying the iron gall ink making kit from us.
The kit also includes your filter cloth, gloves, and spoon, etc.
You also need water, ideally, distilled or reverse osmosis filtered water, though you can use tap water in a pinch.
Next you need vinegar: white vinegar, apple cider vinegar, wine vinegar, just grab some vinegar
And next you need some wine: White wine, red wine, old wine, new wine…
All-righty, now that we have all of the ingredients, lets measure…wait…PUT YOUR GLOVES ON!! This stuff can stain your skin and is slightly toxic.
Great job following safety protocols!
Ok, now we can measure the ingredients.
Measure ¾ cup of vinegar
¾ cup of wine (I like red the best)
And 1 cup of water (Double what is in the picture)
Mix them all together
Measure 1 cup of this mixture
Place it in a pan
Add the Oak galls to this pan
Boil it for about 5 minutes (make sure it doesn’t boil over!)
Measure ½ cup of your remaining liquid
Pour it into an appropriate container
Add the Iron(II) Sulfate to this
And stir to dissolve
Measure another ½ cup of your remaining liquid
And add it to an appropriate container
Add gum Arabic to this liquid
And Stir to dissolve
Allow the oak galls to cool, and filter the liquid through a cloth into a jar
Add the final ½ cup of liquid to the oak gall mush
Filter this liquid through the cloth again
Squeeze out the remaining liquid
Until the oak galls are dry-ish
You should have about 1 cup of oak gall extract
Add the iron(II) Sulfate solution to this extract (don’t forget your gloves like I did!!)
This should now form a dark black/grey liquid
Now add your gum Arabic solution/suspension
Stir this all together thoroughly and you have made ink. I like to filter it once more through the filter cloth after I have made the ink to get any large clumps out. (this part is extremely messy and not entirely necessary, but it helps smooth out the ink concistency)
