Sculptural processes in primary school are called plastic arts. Techniques of the plastic arts are clay, modelling paste, modelling clay, plaster, bronze, wood, stone, wire, sheet metal, aluminium and copper foil, plastic-coated paper and didactically unformed materials. They allow students to express themselves by modelling and building in a variety of materials. The techniques most commonly used in plastic arts in primary education are clay, modelling paste, modelling clay, plastic-coated paper, aluminium foil, wire and didactically unformed materials. Work with the aforementioned materials is focused on modeling, combining, varying and disassembling to shape the relationship between volume and space. This develops visual and tactile perceptions, understanding of form and space, and fine motor skills of the hand. Designing and constructing with these techniques enables the student to experience tangible volume as opposed to the illusion of volume, as is the case in the fields of drawing and painting. The aim of the research was to investigate the success of using techniques of the plastic arts in the visual creative expression of primary school students. The sample consisted of 35 participants, students from the third and fourth grade of Salesian Elementary School in Zagreb. One lesson was held in the third grade and two lessons were held in the fourth grade. The selected techniques were: aluminium foil, wire and clay. The theme for each technique was different. The students encountered the technique of using wire and aluminium foil for the first time. Three categories of success were defined: successful work, average work and unsuccessful work. The categorization of results was achieved on the basis of predetermined evaluation elements appropriate to the chosen technique. The research shows that at least 16% of students successfully used the set technique. The participants were more successful working with new techniques than they were working with clay, which they encounter in the first grade. Learning about a new technique could have contributed to the students' dedication and motivation to work.
