Ildikó's jewellery is created using the ancient technique of enamel firing on copper, typically at temperatures of 820–850 °C. One of her most frequently used methods is cloisonné enamel, where rolled copper wires form the outlines of the design and the enclosed spaces are filled with colourful jewellery enamels. Each piece is fired in the kiln four to five times, from base coating to final polishing. She also works with painted enamel techniques, applying enamel paints to primed copper surfaces. Her collections include pieces inspired by Hungarian and Jász motifs, as well as designs drawn from nature and the surrounding world, resulting in jewellery that is both timeless and contemporary.
