A writing instrument
used to mark on surfaces other than paper, such as glass
. At first glance, it appears to be a colored pencil
. However, there are two major differences. First, instead of graphite
, it is more wax
based. This sounds similar to a crayon
, but it is much stickier
to the touch. Also, instead of being encased in wood
, the “ink” is wrapped in layers of paper. As the wax wears down, more is exposed by pulling a string in the side, and removing a bit of the paper.
They are also known as “grease pencils” (or markers or pens).
As mentioned earlier, china markers are able to write well on a variety of surfaces that most other tools cannot. The other handy attribute is that they are not permanent. With a clean cloth, elbow grease, and the occasional mild solvent, the marks can be removed. This makes it handy for putting temporary marks, such as dating food containers, or marking a laminated piece of paper (a map or checklist).
