ink drawing of a fulgurite — a rough, hollow tube of fused sand

FULGURITE FLUTE

fulgurite, walnut wood, urushi lacquer,
mother-of-pearl
Lightning is a high-energy electrical discharge — a natural act of re-balance between cloud and earth. In an instant, it can heat the surrounding air to over 30,000 Kelvin: five times hotter than the surface of the sun. Where the bolt meets sand, that heat fuses silica into glass.

What remains is a fulgurite — a hollow, branching tube, the path of the strike preserved in mineral form.

This flute, crafted from fulgurite, is more than an instrument: it is an artefact of impact, a conduit of electricity, a vessel of elemental memory.

Through the flow of air, the fossilised flash reawakens as audible vibration.

an extreme event,
released as sound

As a naturally formed glass tube, the fulgurite shapes and amplifies specific frequencies — a wind instrument with no precedent.
The work was developed in dialogue with astrophysicist Michel Breitfellner, tracing the path from geophysical event to sonic articulation.

With flutemaker and musician Stefan Kronsteiner and producer André Lehner, an album is taking shape: a range of fulgurite flutes in conversation with the elements that made them.
