- Fountain pen ink
-
Fountain pen ink is a water-based ink intended for use with fountain pens. Disposable plastic cartridges came into use in the 1960s, but bottled inks are most commonly used, as they usually cost less than an equivalent volume of cartridge ink, and offer a wider variety of colors and properties.[citation needed]Contents
Composition
Because fountain pens operate on the principle of capillary action, ink for them is almost exclusively dye-based. Pigment-based inks (which contain solid pigment particles in a liquid suspension) tend to clog the narrow passages of the pens.[1] Some pigmented inks do exist for fountain pens, but these are uncommon.[citation needed] India ink, a carbon pigment-based ink, also contains a binder (such as shellac), which can quickly clog such pens.[2]
Ideal fountain pen ink is free-flowing, free of sediment, and non-corrosive. These qualities are compromised for benefits of permanence, manufacturability, and use of some widely available dyes.[3]
Durability and security
In the late 20th century, particular attention has been paid by ink manufacturers to the durability of their products against the effects of time, moisture, and efforts at forgery or falsification. [4]
