Permanent Marker Art By Heike Weber

A Permanent Marker is a type of marker pen that is used to create permanent writing on an object. Generally the liquid is water resistant, contains a solvent such as xylene, toluene, or alcoholand is capable of writing on a variety of surfaces from paper to metal to stone. They come in a variety of tip sizes (ultra fine to wide), shapes (chisel point, bullet tip, and wide bristle), and colors (metallic, non metallic, or ultraviolet reactive).
Like spray paint, these markers give off volatile organic compounds and are commonly used in the drawing of graffiti.
Some of the most recently made permanent markers are made from recycled plastic.
The permanent marker was invented in 1952 by Sidney Rosenthal.
