PRINCIPLES OF FORMING LICHTENBERG FIGURES ON WOOD

This paper examines the process of forming Lichtenberg figures on wood, with particular emphasis on the effect of processing time and wood species on the quality and complexity of the resulting patterns. Through controlled experiments using three common wood species: northern spruce, pine and larch. For each wood species, optimal treatment parameters, including discharge exposure duration and electrolyte concentration, were determined to achieve clear, well-developed Lichtenberg figures with branching patterns. The results showed that northern spruce has the best characteristics for forming high quality Lichtenberg figures, while pine and larch require more precise parameter settings due to differences in their electrical resistance and tendency to charring. The obtained results and practical recommendations can be used by artists, designers and woodworkers to develop innovative decoration techniques, create unique interior items and artworks.
