Fractal Burning Machines: The Lethal Voltage Risk, Not Just a “Solution”
The best solution for fractal burning is using a high-voltage woodburning machine. Fractal burning is a technique that creates unique and mesmerizing patterns on wood surfaces by using electricity to create burns that branch out like natural fractals.
⚠️ Serious Safety Warning
Fractal/Lichtenberg wood burning uses lethal voltages (typically 1,000–15,000V from a microwave, neon-sign, or oil-burner transformer). At least 33 people died attempting this at home between 2017 and 2022, most from accidental contact with electrodes, the electrolyte solution, or a live wire. Never touch the wood, electrodes, or solution while the power source is energized — fully disconnect and wait before adjusting anything. Work on a dry, non-conductive floor, never work alone, and keep others away from a live setup. The American Association of Woodturners bans promoting or demonstrating this technique at its events. Commercial “kits” use the same lethal-voltage principle and carry the same risk if misused.

Understanding Fractal Burning
Fractal burning is a popular art form that uses electricity to create unique patterns in wood. There is no DIY high-voltage setup that’s genuinely safe — see why below, along with safer alternatives that get a comparable look.
Fractal burning, also known as Lichtenberg figure or fractal wood burning, is a mesmerizing art form that involves creating intricate patterns on wood using high-voltage electricity. This unique technique results in beautifully charred designs that resemble bolts of lightning, branches, or intricate tree-like structures stretching across the wood surface. To truly comprehend the best solution for fractal burning, it’s important to explore the basics of this captivating art form. Let’s delve into what fractal burning is and discover its fascinating history.
What is Fractal Burning?
Fractal burning is an artistic process that involves passing an electrical current through the wood to create mesmerizing patterns. By passing high-voltage electricity through the wood, branching patterns form that are reminiscent of natural phenomena like rivers, lightning, or tree branches. These patterns are commonly known as Lichtenberg figures, named after German physicist Georg Christoph Lichtenberg, who first discovered them in the late 18th century.
History of Fractal Burning
The history of fractal burning can be traced back to the pioneering experiments carried out by Georg Christoph Lichtenberg. He observed the formation of intricate electrical discharge patterns and documented his findings in a series of writings. However, it wasn’t until the late 20th century that artists and woodworkers began to explore the creative potential of this technique. With advancements in technology and a deeper understanding of electrical conductivity, artists started using high-voltage transformers and other tools to bring Lichtenberg figures to life on wooden surfaces.
In recent years, fractal burning has gained significant popularity among artisans and woodworkers due to the distinctive patterns it creates. The combination of artistic expression and scientific principles makes it an intriguing form of art that captivates the imagination of both creators and spectators. Now that we have a better grasp of what fractal burning is and its historical roots, we can delve into the different solutions available for this unique art form.
Why We Don’t Publish A Conductive-Solution Recipe Or Burn Technique
Earlier versions of this page included the exact conductive-solution recipe (water, baking soda, salt), electrode placement, and voltage-adjustment troubleshooting for fractal burning. We removed all of it. Since 2017, at least 33 documented deaths in the United States have been linked to homemade Lichtenberg/fractal wood-burning rigs, and the American Association of Woodturners bans demonstrating the technique at its events.
Two facts explain why standard precautions (insulated gloves, goggles, ventilation) don’t reliably prevent injury:
- A GFCI outlet does not protect you. It monitors the transformer’s primary (input) wiring. The lethal output comes from the secondary coil, which is galvanically isolated from that circuit — the GFCI cannot detect a fault on the output side and will not trip.
- Unplugging the transformer does not make it safe to touch. The capacitor paired with a microwave oven transformer stores a charge and can deliver a lethal shock long after the unit is disconnected from the wall.
Getting The Look Without The Risk
If the branching, lightning-like pattern is the appeal, these routes get a comparable result without mixing a conductive solution or wiring a transformer:
- Pyrography (wood-burning) pen. Freehand a branching pattern at low, safe voltage.
- CNC laser engraver. Load or design a Lichtenberg-style pattern and let the laser burn it in — no current passes through the workpiece or operator.
- Commercially built, interlocked units. Enclosed Lichtenberg machines with engineered safety interlocks are meaningfully safer than a garage-built rig, but still high voltage — “safer” is not “safe.”
Safe Alternative: Pyrography Pen Kit
The YIHUA 930-IV Pyrography Wood Burning Pen Kit lets you freehand branching, fractal-style patterns at low voltage — no transformer, no capacitor, no lethal current path.

What Can I Use Instead Of Baking Soda For Fractal Burning?
We do not publish alternative conductive-solution recipes. Any water-based electrolyte (baking soda, borax, salt) used with a high-voltage transformer carries the same lethal risk — this exact combination has been linked to at least 33 deaths in the US since 2017.
What Is The Water Mixture For Fractal Wood Burning?
We do not publish exact ratios. Applying any conductive solution before energizing the wood with high voltage is precisely the step that has caused documented fatalities, regardless of the ratio used.
What Solution Do You Use For Wood Burning?
For wood burning, we use a high-quality solution that ensures efficient and safe results. Our solution is specifically designed for wood-burning purposes, providing optimal heat and minimal smoke. It is an ideal choice for various applications, including fireplaces, stoves, and wood-fired cooking.
What Liquid Is Used For Wood Burning?
The liquid commonly used for wood burning is called wood stain or wood dye. It adds color to the wood while preserving its natural texture and appearance.
What’s A Safer Way To Get A Similar Look?
A standard low-voltage pyrography pen or a CNC laser engraver can produce a comparable branching, fractal-style pattern without any transformer, capacitor, or conductive solution involved.
Conclusion
Finding the best solution for Fractal Burning involves considering various factors. It’s important to prioritize safety and choose a method that suits your skill level. The use of appropriate equipment and understanding the process is crucial. Additionally, seeking guidance from experienced craftsmen can greatly benefit your woodworking projects.
Keep in mind that safety comes first and the chosen method should enhance the artistic outcome.
