The material in this pen is as antique and natural as the world: lava from the Etna volcano. in south Italy. Nevertheless, it has several characteristics that render it unique in the manufacturing of writing instruments. Visconti has successfully produced a material containing pure basaltic lava, catalysed together with resin in a formula – patented thus obviously kept secret -whose extraordinary characteristics practically transforms it into a material perfectly fit to writing instruments.

The clip, the rings and the metal accessories are all in bronze: Natural bronze like the antique formula, that does not require plating or protection treatments. Over the time, Natural bronze alters its original (almost pink) color. It can be easily polished with special cleaning pans. The Lava material is a natural material; when daily used, the pen keeps its original dark grey color. If the pen is not used for a while or exposed to strong light it can become light grey. This is a certification of a real bio material. To regenerate the material, it is simple: just treat the pen with a common moisturizer.
