Lot 8 | SOLIDIFIED LIGHTNING: AN EXTRAORDINARILY LARGE FULGURITE
Estimate value
£ 50 000 – 80 000
This remarkable natural sculpture was formed in one ten thousandth of a second, from the interaction of lightning with earth. Driven by electrical potential of around 1 billion volts, lightning heats the air to approximately 30,000 degrees Kelvin. If conditions are right, these strikes can melt the earth into a kind of glass called lechatelierite, more commonly known as fulgurite, from the Latin fulgur (lightning).Fulgurites contain a hollow internal glass tube, with a rough exterior which flares into spiky ridges and undulating channels. Sand grains can also be preserved, as with the present piece, and are a remnant of the instantaneous transformation of earth to glass. Owing to their rarity and the difficulty of excavation, fulgurites are usually only small, measuring just a few centimetres in length. The present example is one of the largest and most sculptural to have appeared on the market.27in. (69cm.) long
