the mastery expressed by ancient works
must be evaluated as like as artworks.
Since prehistory, the first exponents of humanity had identified, in the skins of the animals that they were used to hunt, a possible protection from unpleasant weather.
Leather, however, is an organic material that is subject to putrefaction.
Probably due to fortuitous junctures, human beings of that era had realized that if leather are exposed to specific conditions, they can be preserved for a long time.
These specific contitions were represented from the smoke of hearths in campsites and from the immersion in water with branches and leaves of trees.
These are the first and rudimentary tipes of aldehydes
vegetal tanning, which is obtained through the use of tannins.
Tanning processes have ahd as their bases the use of aldehydes and tannins for many centuries and have maintained the same technology until, in second half of nineteenth century, was introduced the use of drums.
Another important innovation was the discovery, at the beginning of twentieth century, of the possibility to use a new product to tan: trivalent chromium. The substances that comprise this element have the ability to bind, in a stable and permanent way, to the fibers of leather.
Chrome tanning is nowadays the most used method inside the sector, even if also the other modes are mantained.
Thanks to these instruments we can, today as it was in prehistory, transform and give a new value to a waste product that results from food use and make it a well-rounded, lasting, quality and extremely beautiful material.
