Butte

"Butte," a new work presented at the "Figure of Light" lighting exhibition held at Milan Design Week 2022, will be newly created using fly ash concrete, a modern version of Roman concrete. Since the lighting was inspired by the skylight of the Pantheon in Rome, I thought it would be possible to quote the material as well.
Roman concrete contains volcanic ash in its raw materials and is durable for more than 2,000 years, compared to 50 to 100 years of ordinary concrete.
In modern times, fly ash, a type produced when coal is burned in thermal power plants, is also known to increase strength and durability when mixed with cement. As a byproduct, it is a material that can reduce CO2 emissions by an average of 41%, or 50 kg per ton, compared to the same amount of concrete produced.
