Lichtenberg burning works by passing electricity at very high voltage between two electrodes while they are in contact with a piece of wood. ... The electricity seeks the path of least resistance while generating heat along the wood surface and between the electrodes, burning the wood as it goes.

How is fractal burning done?

Fractal burning is a relatively new technique which creates patterns in wood that resemble branching or fractal patterns by applying electrical current from a high-voltage source across wood items that may have been soaked with a chemical solution.

What is needed for fractal burning?

The fractal burning process typically uses a high-voltage transformer, often repurposed from a microwave oven, to flow current across wood items that have been soaked with a chemical solution.
