Burning wood using a high-voltage transformer from a microwave is a fascinating technique that combines science with art. When the wood is suitably moistened and electrodes are attached, an electric current begins its journey through the wood fibres, creating organic patterns reminiscent of tree roots or lightning bolts. This process is also known as the Lichtenberg technique and produces unique visual effects that cannot be achieved with traditional firing methods.
How does it work?
The process itself requires a high voltage – and that’s where the transformer from the microwave comes in to provide sufficient electricity. After the wood has been moistened (most often with a solution of water and an electrolyte such as baking soda), the electrodes are applied to its surface. The electricity seeks the path of least resistance, leaving unique patterns. If the electrodes are moved across the surface of the wood, the patterns can interconnect and cover a larger area. However, if the electrodes are held in place, deeper and darker burnt patterns are created.
Art and experimentation
The charm of this technique lies in its unpredictability. Although it is possible to partially influence the direction of the discharges, nature always has the last word. That is why it is interesting to combine this method with traditional art techniques. In the future, I plan to combine burnt patterns with Anka’s drawings and paintings. This combination can create completely new works of art where technology meets human creativity.
Possibilities of use
Burnt patterns have a wide range of uses – from decorations on wooden boards, to art paintings, to personalised items such as tables or picture frames. When the technique is combined with paint, engraving or even epoxy resin, breathtaking design pieces are created.
If this technique fascinates you, don’t hesitate to experiment! All it takes is a little creativity, care and patience – and the result will be unique wooden artefacts that bear the signature of nature itself. 🌿🔥
