Fountain Pen

A fountain pen is a nib pen that, unlike its predecessor, the dip pen, contains an internal reservoir of liquid ink. The pen draws ink from the reservoir through a feed to the nib and deposits it on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of a Pasteur pipette (eyedropper) or syringe, or via an internal filling mechanism which creates suction (for example, through a piston mechanism) to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges.

Original reservoir pens

The earliest historical record of a reservoir pen dates back to the 10th century. In 973, Ma'ād al-Mu'izz, the caliph of the Maghreb, demanded a pen that would not stain his hands or clothes, and was provided with a pen that held ink in a reservoir and delivered it to the nib, which could be held upside-down without leaking, as recorded in Kitab al-Majalis wa 'l-musayarat, by Qadi al-Nu'man al-Tamimi (d. 974). No details of the construction or mechanism of operation of this pen are known, and no examples have survived.
