The vast majority of leathers undergo a process of mineral tanning. The imperfections are covered up with pigmentations, and artificial grains are pressed into the hides. This process allows the colours to set quickly and is consequently less costly. Nonetheless, for this process, chromium, and other heavy metals and chemicals are used. These elements are extremely polluting and potentially toxic. Although infrequent, they can produce allergic reactions when they come in contact with the skin.
The ancient process of vegetable tanning, which is much more natural and ecologically safe, makes use of natural dyes from plants and trees (oak, acacia, chestnut, mimosa, etc.). This process takes more time and is more laborious. However, it gives the leather a more authentic appearance and allows it to develop a beautiful natural patina and an incomparable texture as it ages.
Bleu de Chauffe is a company concerned with reducing the ecological footprint of its activity at every stage of production. Naturally, we have made the choice to only use vegetable tanned leathers, as much for environmental reasons as for their superior quality, unique appearance and the natural patina they develop with age, because each and every Bleu de Chauffe leather bag is made to last.
