Fractal Burning: Unveiling the Art of Lichtenberg Figures
Introduction to Fractal Burning:
Fractal burning, commonly known as Lichtenberg Figure burning, is an enthralling wood burning technique that utilizes a specialized machine to apply high-voltage electricity, resulting in intricate, branching patterns on wood surfaces. The process yields stunning designs resembling lightning bolts or the graceful sprawl of tree branches, creating a captivating visual representation of the electrical discharge's path.
If you decide to explore this artistic pursuit, it is imperative to exercise caution and thoroughly educate yourself on the intricacies of the fractal burning process, the operation of fractal burning machines, and the associated risks. It's crucial to note that these machines can pose significant dangers and potential hazards, which must be handled with utmost care and expertise to ensure both personal safety and the safety of others.
History and Origins:
The origins of fractal burning can be traced back to the work of Georg Christoph Lichtenberg, an 18th-century German physicist renowned for his discoveries in the field of electricity. Lichtenberg extensively studied electrical discharges, leading to the development of the Lichtenberg Figure, which inspired contemporary artists and woodworkers to explore its aesthetic potential.
Evolution of Fractal Burning:
Initially utilized as a scientific experiment to study electrical phenomena, fractal burning has evolved into a popular art form embraced by artisans and woodworking enthusiasts worldwide. Over time, artists have refined the process, experimenting with various wood types, electrical setups, and techniques, leading to the creation of intricate and diverse patterns that are both visually stunning and conceptually intriguing.
How I Fractal Burn:
- Wood Selection:
The beauty of fractal burning lies in its versatility. Any type of wood can be employed, allowing for endless possibilities and unique creations.
- Wood Preparation:
To set the stage for the mesmerizing electrical patterns, I meticulously prepare the wood surface. A thorough sanding with a p120 grit ensures a smooth and even texture, creating an ideal canvas for the impending transformation.
- Process of Burning:
The magic unfolds with the application of an electrolytic solution to the wood's surface, significantly reducing its resistance. High-voltage electricity (exceeding 2100 volts) is then administered through a specially crafted fractal burning machine. This machine employs two electrodes placed on the wood, initiating a captivating process. The current, facilitated by the electrolytic solution, induces the wood to burn, forming intricate figures known as Lichtenberg figures or fractal burns.
- After Burning:
The aftermath of fractal burning reveals a surface adorned with burned-in patterns. The next steps involve removing the ashes, a critical process to unveil the true beauty of the lightning-like patterns. I prefer washing out the ashes immediately after burning with water and a brush, as it often results in the most vivid and clear patterns. Alternatively, the use of an air compressor and a steel brush the following day is another effective method.
- After Ash Removal:
With the ashes gone, the meticulous sanding process begins. This step not only smoothes the surface but also enhances the visibility of the intricate patterns. Care must be taken during sanding to avoid removing too many details. After sanding, the artwork can be finished in various ways, such as filling in the fractals with epoxy for a stunning visual effect.
Fractal Burning Machine:
At the heart of this artistic process lies the fractal burning machine. This setup, equipped with two electrodes, generates high-voltage electricity essential for the burning process. I've crafted three such machines, each purpose-built from spare parts. The transformers I typically use are sourced from microwave ovens, though I've also constructed one using a transformer from an oil burner. However, it's crucial to note that building a fractal burning machine involves inherent risks. For those without sufficient knowledge of electricity and related safety measures, I strongly advise against attempting.
