In the Maori culture of New Zealand, the head was considered the most important part of the body, with the face embellished by incredibly elaborate tattoos or ‘moko,’ which were regarded as marks of high status. Each tattoo design was unique to that individual and since it conveyed specific information about their status, rank, ancestry and abilities, it has accurately been described as a form of id card or passport, a kind of aesthetic bar code for the face. After sharp bone chisels were used to cut the designs into the skin, a soot-based pigment would be tapped into the open wounds, which then healed over to seal in the design. With the tattoos of warriors given at various stages in their lives as a kind of rite of passage, the decorations were regarded as enhancing their features and making them more attractive to the opposite sex.
Yeah, yeah, we know that tattoos are permanent, expensive, and straight-up painful—but with style-savvy celebs like Rihanna, Cara Delevingne, Miley Cyrus and Kylie Jenner regularly seen showing off their cute tats, we’re still totally feigning for some fresh ink. These stars don’t have full sleeves, but instead rock smaller, simpler designs on their skin.
According to George Orwell, coal miners could develop characteristic tattoos owing to coal dust getting into wounds. This can also occur with substances like gunpowder. Similarly, a traumatic tattoo occurs when a substance such as asphalt is rubbed into a wound as the result of some kind of accident or trauma. These are particularly difficult to remove as they tend to be spread across several layers of skin, and scarring or permanent discoloration is almost unavoidable depending on the location. An amalgam tattoo is when amalgam particles are implanted in to the soft tissues of the mouth, usually the gums, during dental filling placement or removal. Another example of such accidental tattoos is the result of a deliberate or accidental stabbing with a pencil or pen, leaving graphite or ink beneath the skin.
