Ok...so...What are Permanent Markers? Well, they are writing instruments used to apply permanent writing onto objects. The ink applied is permanent on almost all surfaces including paper, metal and stone. They are made to be water resistant so it can be pretty difficult to get off.

Permanent markers contain xylene, toluene and sometimes alcohol. They come in a variety of tip sizes, colours and shapes, depending on which one you prefer.

They were invented by Sidney N. Rosenthal in 1952 and the most popular permanent marker is the SHARPIE for reasons I do not know.

There are a range of solvents which can remove the ink of a permanent marker off specific surfaces including paint thinner and alcohol, both of which I am using in my experiment.
