Plastic art refers to art forms that involve the manipulation of materials to create three-dimensional works. This includes mediums such as sculpture, ceramics, and installations. Artists use various techniques to shape and mold materials like clay, metal, and plastic, allowing for a tactile and visual experience. Unlike traditional painting or drawing, which are primarily two-dimensional, plastic art emphasizes volume and space. Notable examples include the works of Henry Moore and Louise Bourgeois, who explored human forms and emotions through their sculptural pieces. This art form invites viewers to engage with the artwork from multiple angles.
