liquid chalk marker and chalk marker difference

Chalk markers and liquid chalk markers are both pens that contain ink, but the main difference between the two is the type of ink they contain. Chalk markers use water-based pigment ink that is opaque, water-resistant, and reactivated with a damp cloth. Liquid chalk markers use a special kind of liquid ink that is specially formulated for use on surfaces such as slate, chalkboard, glass, and plastic. The liquid ink acts more like a liquid paint when used, but is less smudge resistant than the pigment ink of a chalk marker.
