Ricette: French Logwood Ink

This ink has a beautiful bluish-black hue. Freshly applied, it is pale grey, but becomes much darker while drying. When exposed to light, it only fades slightly, loses its blue tint and becomes blacker.

Lavorazione

Passo 1: Put the gall apples in a textile bag and crush the apples with a hammer. Then roughly pulverize them in a mortar and put them in a cooking pot. Add the logwood. Pour water over the ingredients and bring it to a boil. Let the mixture reduce to half of the original amount.

Passo 2: Filter the ink while still boiling, then stir in copper sulphate, iron (II) sulphate, potash alum and gum arabic.
French logwood ink forms a sediment, especially when it is fresh. It is best to let it sit for a while and clarify.
Prolonged storage may cause the formation of a skin on the surface of the ink, which can be skimmed off or filtered.
