Biro ink, commonly used in ballpoint pens, is primarily made of a mixture of dyes or pigments, solvents, and various additives. The solvent, often an oil or a wax-based compound, helps to maintain the ink's fluidity and viscosity, allowing it to flow smoothly through the pen's ballpoint. Additives may include surfactants to improve ink performance and stabilizers to enhance shelf life. This formulation results in a quick-drying, smudge-resistant ink that adheres well to paper.
no they were made around 1938
Péter Biros was born in 1976.
Early biros were used in the RAF primarily because they provided a reliable writing instrument that performed well at high altitudes and in various weather conditions. Unlike fountain pens, which could leak or freeze in cold temperatures, biros utilized a ballpoint mechanism that prevented ink from flowing uncontrollably. This made them practical for pilots and personnel who needed to write in challenging environments without the risk of damaging important documents. Additionally, their portability and ease of use contributed to their adoption in military settings.

what was the ink made from in WW1
Ink.
To make a new biro work, remove the cap and gently tap the tip against a hard surface a few times to get the ink flowing. You may also need to scribble on a piece of paper to help start the ink flow. Keep the pen in an upright position to prevent any potential leaks.
