Chrome tanning is a process of leather processing, quite simple and cheap, with very recent origins; since in 1910, the first chrome tanning was patented which experienced a significant expansion in the industrial sphere while the post-war period ending.
It is a process based on trivalent chromium ability to form complexes with carboxyl groups of skin collagen.
About 80-90% of all leather produced in the world has been chrome tanned; it is possible to use this technique on bovine skins, sheep skin, lambs and many other animals from which it is possible to find a skin.

We are in a world where technology makes our reality go faster and faster; perhaps we should stop every now and then to think about what kind of products we need to use. We should take into consideration technologies that allow us to obtain better products. The difference between these two kind of tanning process shoudl teach us a valuable lesson: purchase something that respects quality, durability and health criteria, rather than a low cost product of poor quality which is also bad for the environment.
Vegetable tanned leather should be a protected legacy; a product worthy of having care and attention in all its processing phases; it is not ashamed to show the scars and signs suffered over time. The leather is proud of them, and makes them his unique and unrepeatable identity, to represent a beauty that has matured with the use and experience of its owner.
Vegetable tanned leather is a legacy to be protected, just like the world we live in.
