Every piece of furniture from Laviture is individually handmade from hardened Basaltic volcano lava. This type of lava is very thick and flows slowly. When cooled rapidly, its cellular networks form astounding hexagonal columns than can be shaped and woven into extremely strong fibers. Basalt fibers have been around since the 1920s. After World War II, they were largely used in the USA as well as Europe and the USSR for military aircraft manufacturing. The process and material was actually considered Classified until 1995, which is why so few pieces made with it exist today.
