The ETHERGRAF® tip microscopically “scratches” paper oxidizing it and leaving a light but indelible stretch.
Due to its porosity, the common paper – that is the cellulose not trated paper (formed by vegetable fibers bonded through a process that is called “felting”)- is in fact a material which perfectly reacts to the passage of the metal tip.
The presence of bonding agents, mineral fillers, dyes or additives in paper compromises its natural absorption capacity. The consequence is that the oxidation of the tip is not allowed, or only partially allowed, at the transit of the ETHERGRAF® tip.
