How to “Electrocute” Wood: Not a Real Treatment

No, this is not a real wood-treatment method — “electrifying” wood does not increase its durability or resistance to insects and decay. What people usually mean by this search is the Lichtenberg/fractal-burning technique, which uses high-voltage current to burn branching patterns into wood. That technique is genuinely lethal: at least 33 documented deaths in the US since 2017.

This process is known as wood electrification and can be performed using various methods such as direct current (DC) or alternating current (AC). It is important to follow safety guidelines and regulations when attempting to electrocute wood to ensure personal safety and prevent damage to the wood.

By electrifying wood, you can enhance its longevity and make it suitable for outdoor applications.

How Electricity Interacts With Wood

Electricity interacts with wood in an intriguing manner, as it can be used to electrocute the material, transforming its appearance and properties. By carefully applying an electrical charge, woodworkers can create fascinating patterns and enhance the wood’s natural beauty.

Wood is a versatile and commonly used material in many applications. But have you ever wondered how electricity interacts with wood? In this section, we will explore the conductivity and resistance of wood when subjected to electrical currents, as well as the effects on different types of wood.

Conductivity And Resistance:

• Wood is generally considered a poor conductor of electricity due to its cellular structure and high resistance to electrical flow.
• The conductivity of wood varies depending on factors such as moisture content, species, and temperature.
• In its natural state, wood contains moisture, which increases its conductivity compared to dry wood.
• However, wood’s conductivity is still much lower than metals or other materials commonly used to conduct electricity.

Effects On Different Types Of Wood:

• Softwoods, such as pine or cedar, have a higher moisture content and generally exhibit higher conductivity compared to hardwoods.
• Moisture acts as a conductor in wood, so higher moisture content can increase its electrical conductivity.
• Hardwoods, such as oak or maple, have a lower moisture content and therefore lower conductivity compared to softwoods.
• The density and chemical composition of wood also affect its resistance to electrical currents.
• Wood with higher resistance will experience greater energy dissipation and less penetration of electrical currents.

Wood is a relatively poor conductor of electricity due to its high resistance, but its conductivity can vary depending on factors such as moisture content, species, and temperature. Softwoods generally exhibit higher conductivity than hardwoods due to their higher moisture content.

Understanding how electricity interacts with wood helps in various fields, such as woodworking, construction, and electrical engineering applications.

Why We Don’t Publish Wiring, Drilling, Or Power-Source Steps

Earlier versions of this page included instructions for wiring wood to a power supply, drilling holes for embedded wires, and connecting mains-level electricity to wood for lighting or “electrification” effects. We removed all of it. Running exposed conductive wire and mains-level current through or across untreated wood — whether for a Lichtenberg-style burn or an embedded-wiring lighting project — creates a real risk of electrocution and fire, not just for the person doing the wiring but for anyone who touches or displays the finished piece later. Since 2017, at least 33 documented deaths in the US have been linked to homemade high-voltage wood-burning rigs specifically, and the American Association of Woodturners bans demonstrating that technique at its events.

Two facts that apply specifically to the Lichtenberg/fractal-burning version of this:

• 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 power source 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.

Safer Ways To Get An Electrified Or Branching Look

If you want the visual effect of “electrified” or branching wood without wiring mains power into or through the piece:

• Pyrography (wood-burning) pen. Freehand a branching, lightning-like pattern at low, safe voltage.
• CNC laser engraver. Load or design a branching pattern and let the laser burn it in — no current passes through the workpiece or operator.
• Battery-powered LED strips or pucks, mounted on the surface (not embedded inside drilled channels) using low-voltage (5V/12V) products designed for that purpose, if the goal is a lit-up display piece.

Frequently Asked Questions For How To Electrocute Wood

How Do You Make Lightning Effect On Wood?

To create a lightning effect on wood, you can use techniques such as wood burning or carving with a thin, jagged pattern.

What Is It Called When You Electrocute Wood?

“Electrifying” or “electrocuting” wood usually refers to the Lichtenberg/fractal-burning technique — passing high-voltage current through a conductive solution on the wood’s surface to burn branching patterns. It is not a real wood-preservation or durability treatment.

How To Do Fractal Burning On Wood?

We do not publish build steps for this. Fractal (Lichtenberg) burning uses a high-voltage transformer to burn branching patterns into wood, and at least 33 documented deaths in the US have been linked to homemade rigs since 2017 — a GFCI outlet does not protect you because the lethal output comes from a secondary coil that is electrically isolated from the circuit a GFCI monitors. See our full explanation of the risk for why we recommend a pyrography pen or CNC laser engraver instead for a similar branching look.

How Many Volts Do You Need To Burn Wood?

The voltage required to burn wood depends on various factors and cannot be determined precisely.

Conclusion

Electrocuting wood can be a fascinating process that brings out its unique characteristics. By following proper safety precautions and using the right equipment, you can transform ordinary wood into something extraordinary. The electrical current creates intricate patterns and textures, adding a new dimension to your woodworking projects.

Whether you want to create stunning pieces of art or enhance the aesthetic appeal of furniture, electrifying wood offers endless possibilities. Remember, experimentation is key when it comes to achieving the desired results. The voltage, duration, and type of wood all influence the final outcome.

Be sure to document your process and learn from your experiences to further refine your technique. As with any woodworking technique, practice makes perfect. So, don’t be afraid to start small and gradually work your way up to more complex projects.

With time and dedication, you’ll develop your artistic style and create one-of-a-kind pieces that showcase the beauty of electrified wood. Let your creativity flow and enjoy the electrifying journey of working with wood.
