Abstract: A novel system of marking substrates using pen devices containing pituitous colorants is described. Preferred applications for such marking devices are art and craft products made by children, students and novice or professional artists. The method of marking comprises dispensing a quantity of pituitous liquid color composition through an applicator device to a visible scene, and pulling the dispensed color composition into one or more strings. The drawn string can be maneuvered to mark the substrate in a novel and exciting way so as to produce a variety of markings including art and craft works. The deposited color composition dries at ambient conditions resulting in permanent or semi permanent art works.
