Rollerball pen

Rollerball pens are writing instruments which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pen. The characteristics of these less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give rollerball pens their distinctive writing qualities.

The rollerball pen was initially designed to combine the convenience of a ballpoint pen with the smooth “wet ink” effect of a fountain pen. Gels usually contain pigments, while liquid inks are limited to dyestuffs, as pigments will sink down in liquid ink (sedimentation). It is the thickness and suspending power of gels that allows the use of pigments in gelled ink. Using pigments (the same pigments that are used in paint) yields a greater variety of brighter colors than is possible in liquid ink. Gels also allow for the use of heavier pigments with metallic or glitter effects, or opaque pastel pigments that be seen on dark surfaces.

Writing with liquid ink pens cannot be seen on dark surfaces because inks containing dyes need a light colored, reflective background, because dyes do not reflect light by themselves, in the way that pigment particles do. Dye molecules absorb all but a particular wavelength of light, so light must pass through the ink and bounce off a reflective background in order for our eyes to see the color of the ink.

Pen History

Ancient Egyptians had developed writing on papyrus scrolls when scribes used thin reed brushes or reed pens from the Juncus Maritimus or sea rush. In his book A History of Writing, Steven Roger Fischer suggests that on the basis of finds at Saqqara, the reed pen might well have been used for writing on parchment as long ago as the First Dynasty or about 3000 BC. Reed pens continued to be used until the Middle Ages although they were slowly replaced by quills from about the seventh century.

The quill pen was used in Qumran, Judea to write some of the Dead Sea Scrolls, and then introduced into Europe by around 700 AD. It was used in 1787 to write and sign the Constitution of the United States of America. The Dead Sea Scrolls discovered in 1947 on the northwest bank of the Dead Sea date back to around 100 BC. At that time they were written in Hebrew dialects with bird feathers or quills. After the fall of the Roman Empire, Europeans had difficultly in obtaining reeds and began to use quills. There is a specific reference to quills in the writings of St. Isidore of Seville in the 7th century. Quill pens were used until the nineteenth century.

A bronze nibs was found in the ruins of Pompei showing that metal nibs were used in the year 79. There is also a reference in Samuel Pepys’ diary for August 1663. A metal pen point was patented in 1803 but the patent was not commercially exploited. John Mitchell of Birmingham started to massproduce pens with metal nibs in 1822. During the 19th century metal nibs replaced quill pens. By 1850 the quality of steel nibs had improved and dip pens with metal nibs came into generalized use.

The earliest historical record of a reservoir fountain pen dates back to the 10th century. In 953, Ma’ād al-Mu’izz, the caliph of Egypt, demanded a pen which would not stain his hands or clothes, and was provided with a pen which held ink in a reservoir and delivered it to the nib via gravity and capillary action.
