Hydrochloric acid, "dilute", S.S.P., 12.5 gramsĭye (C.I. The formula for the standard writing ink is: This standard ink is similar to some of the commercial writing inks. This formula was written originally to provide ink for use in post-office lobbies, where the conditions are devastating to pens.

one part powdered gum arabic, two parts copperas, three parts crushed galls, and 30 parts water, all by volume." Medieval scribes had their own favorite sources, however: acorns, walnut shells and, most often, the small protuberances that grow on oak leaves in reaction to the eggs of certain parasite wasps. is the brown substance found in the bark and leaves of trees. In its natural and impure state copperas has a green tinge, hence the incorrect association with copper. ".Copperas is ferrous (or iron) sulphate, which is available from any drugstore as a dietary supplement. Then take 2 ounces of good green copperis the larger the better and having first washed off the filth put in to the rest and also a piece of clear gum, about as big as a walnut to set the colour and it will be fit for use. Take 5 ounces of the best Nuttgalls, break them in a mortar but not in small pieces, then put the gall into one quart of clear rain water or soft spring water, let them stand 4 or 5 days shaking them often, then take 2 ounces of white gum arabick, 1 ounce of double refined sugar, 1 piece of indigo and put in the same and shake them well and let them stand 4 or 5 days more. Too large a quantity of gallnuts will make the ink lose its intensity, but it will remain resistant to water and alcohol. Too much of the iron salts will make the ink turn a rusty brown with darker edges, and it may also eat into the paper. To avoid the formation of mold, add 5% of volume of strong gallnut extract and boil for 5 minutes. After this, allow it to set for a few days, then filter and pour into the ink bottle. The liquid will turn black and can be used immediately, but it will reach its most intense blackness if it is stirred frequently for one or two months. Into this liquid, pour in the ground-and-soaked gallnuts. In the remaining volume of water, dissolve the ferrous sulfate and the gum. Grind the nuts to a fine powder and place into a bowl. Add 1 gram of carbolic acid to keep mold from forming. Dissolve the ferrous sulfate in water and add it to the liquid. Dissolve gum Arabic in a small amount of water and add it to the liquid. Skim off the mold and pour the liquid through a filter. In a few weeks, mold will cover the top surface. Grind the gallnuts to a fine powder and immerse in half of the water. Before experimenting with these recipes, you must consider the risks and accept responsibility for whatever happens.
There are also toxic environmental risks in mixing and disposing of these inks and ingredients. On this page I share some old recipes with students who would like to experiment with old ink.īeware!
