Playing with the patina on the zippo lighter plate is not patina, but wear. Because the zippo lighter will be affected by the pH of the hand skin after playing with it, and the natural oxidation of the air on the zippo lighter. It is the oxidation wear of zippo lighter shell, not the patina.

Zippo patina means that you don't need to wash your hands too often when using a lighter, so that the sweat on your hands naturally touches its surface. After a long time, the metal will be oxidized, and the original color will naturally become darker. In fact, this covers zippo patina.

Rubbing Z with hands, fine sandpaper or even fur is not patina, nor is it patina when it turns yellow by initial oxidation, nor is it patina when it rusts by chemical oxidation. It is a thick layer of sweat secreted by hands, mixed with dust and dander oil, formed after years of tempering.

Because the oxide gradually thickens, the sweaty hand will not immediately adsorb on the surface after contact, but just slide on the surface, so it is better to play slowly with a slight sweat. When the surface becomes astringent, it means that it is saturated, and it needs to stop at this time. After it is completely dry, the next cycle or 1.2 days or a week's play interval. B because the initial oxide layer is fragile, it is not suitable for touching with fingers, which will make the oxide layer uneven. After a while, both hands will play well.
