Soot ink
Carbon black inks are easy to make and the oldest black inks . They have been around since the 3rd millennium BC. Known and were used quite often until the Middle Ages .
Composition and other details
Carbon black inks consist of the components water, carbon black and various binders such as gum arabic , cherry gum , honey, various oils, resins, isinglass , various animal glues or protein. The binder is dissolved in warm water. Then the carbon black pigment is mixed in. The addition of wine or vinegar improves the wetting and thus the miscibility of the pigment with the binder. The correct amount of soot is simply determined by writing samples. If the ink can be smeared very easily after drying, the amount of binder must be increased. The main disadvantage of soot ink is its sensitivity to water.
