In the midst of the Renaissance, among the secrets hidden in the manuscripts of Leonardo da Vinci, a discovery emerges that still surprises the world of research. On the 87R sheet of the Madrid II code, preserved in the National Library of Spain, Leonardo noted:
They will be better preserved if they are rude and burned on the surface than in any other way.
A discreet, almost invisible phrase that describes a procedure known today as the surface carbonization of the wood, a technique that is revolutionizing the way we think of sustainable bio -architecture.
This manuscript, one of the most technical and least known among Leonardo’s works, represents a mine of information on engineering, architecture, mechanics and materials. And precisely from these pages, thanks to the joint work of three Italian scholars – Annalisa di Maria, the highest world expert on Leonardo da Vinci and member of the UNESCO club in Florence, Andrea da Montefeltro, molecular and sculptor biologist, and Lucica Bianchi, art historian – emerged a discovery capable of connecting past and future.
Surface carbonization of the wood
The superficial carbonization of the wood is not only a historical curiosity, but a method that offers concrete and measurable advantages in the protection and duration of the material. Today we know that this technique:
Leonardo had sensed all this in an era in which wood conservation was entrusted to rudimentary methods, such as the underwater diving used in the Venetian poles. His vision anticipated, with centuries in advance, the cardinal principles of contemporary bio -architecture, based on durability, efficiency and low environmental impact.
Leonardo da Vinci, the choice of essences and the application of the technique
In the Madrid II code, Leonardo does not limit himself to describing the superficial carbonization technique, but enters the detail of materials, processing phases and specific uses:
A scientific approach ante litteram, based on empirical observation, but also on the in -depth knowledge of the properties of the materials, well beyond what is described by Pliny the Elder, Vitruvius or Palladio. In fact, surface carbonization does not appear in any of these texts, a sign that Leonardo elaborated this technique in total autonomy, through direct experiments and original reflections.
How Leonardo’s technique applies today
The superficial carbonic of wood carbonization is now used in advanced areas of the design:
The world of bio -architecture and the science of materials looks with growing interest in this rediscovery Leonardo. University, research centers and architecture studies are reinterpreting an ancient technique in a modern key, which today proves to be fundamental to build in a responsible and lasting way.
This is not only a archive curiosity, but a concrete lesson of sustainable innovation, which reminds us how the future can draw strength from the roots of the past. Leonardo da Vinci, once again, proves to be a pioneer of a circular thought, in which nature, science and creativity coexist in perfect balance.
