Gel pens

Gel pens are gel inked ballpoint pens. They come in many different sizes and in a huge variety of colours. They are primarily used for thin patterns or writing, but can be used for colouring small areas in a specific colour. Image File history File links Pens. ... Image File history File links Pens. ... Ballpoint pen, disassembled (top) and complete (bottom) A ballpoint pen (also eponymously known in British English as a biro and pronounced bye-row in Britain but sometimes bee-row elsewhere), is a modern writing instrument. ... A pattern is a form, template, or model (or, more abstractly, a set of rules) which can be used to make or to generate things or parts of a thing, especially if the things that are generated have enough in common for the underlying pattern to be inferred or discerned...

Design

The general design of a gel pen is similar to that of a ballpoint pen, with a barrel containing the writing mechanism and a cap. Most gel pens have grips, some made of rubber and some of plastic.

What distinguishes a gel pen from a ballpoint pen is the gel ink which consists of pigment suspended in a water-based gel.[1] The pigments are typically copper phthalocyanine and iron oxides, and the gel is made up of water and biopolymers, such as Xanthan gum and tragacanth gum, as well as some types of polyacrylate thickeners. Since pigments are opaque, gel pens are available in bright colours that stand out on darker paper. Natural Ultramarine pigment in powdered form. ...

Thickening agents, or thickeners, are substances which, when added to the mixture, increase its viscosity without substantially modifying its other properties, like eg. ... A substance or object that is opaque is neither transparent nor translucent. ...


By contrast, ball-point pens use a paste ink based on a solution of a dye solute in an alcohol solvent, and fountain pens use a dye solute in a water-based solvent. India ink (based on carbon black pigment) is perhaps the ink closest to gel ink, although it is usually made with an alcohol and shellac-based solvent. In other words, no other kind of pen (besides "paint pens") can write on dark paper and appear as bright as a gel pen.

For the post-punk band, see Shellac (band). ...


Another trait of gel pens is that they resist common laboratory analysis. The American Secret Service has maintained the International Ink Library for many decades. Because manufacturers change their ink formulas slightly from year to year, thin-layer chromatography (TLC) can be used on ink from traditional pens to trace the manufacturer and date of manufacture of most inks. The pigments in gel ink do not dissolve, and therefore cannot be analyzed with TLC.[2] Forensic chemistry is the application of chemistry to law enforcement or the failure of products or processes. ...

Colours

The colours can range from dark browns to bright yellows. There are also several different styles of colouration:

  • Glittered — These are colours with glitter added to them to give a sparkly effect. Cosmetic-grade ground glass is used as the additive in Sakura-brand pens. Some lose their glitter if "erased".
  • Milky — These come in pastel colours, often pink, light blue, lavender, pale green, pale orange, and white.
  • Mixed — These are different colours mixed together in the ink to for an interesting effect of ink colour. These usually use pastel colours.
