What Architecture's Foundations Teach Us About Leather Tanning

The "foundation" in architecture, and "tanning" in leather goods.
At first glance they seem to be two worlds that never intersect, but in fact they are deeply connected by an absolute truth of craftsmanship: "the invisible foundation determines all future value."

Massive concrete walls, beautiful silhouettes soaring into the sky. When we look at a building and are moved to call it "magnificent," what we see is always "the part that appears above ground."

Yet architectural professionals all say the same thing: "What truly matters is the 'foundation,' hidden and unseen beneath the ground."

Needless to say,
no matter how lavish the decoration, if the foundation is weak, the building cannot withstand the test of time and will eventually tilt and collapse.

Exactly the same can be said of the world of "leather goods." The cornerstone of a bag or wallet is the foundational process known as "leather tanning."

■ The first cornerstone in the transformation from "hide" to "leather"

The leather items we hold in our daily lives were not supple like that from the start. Originally, they are natural "hides (skins)" given to us by animals.

Left as they are, they rot from moisture, and once dry they turn as hard as a board. Tanning is the process of literally soaking these delicate "raw materials" with chrome (chemicals) or plant tannins, transforming them into "leather" that does not rot, is supple, and can be used as a tool for decades.

Even luxury exotic leathers such as crocodile, python and elephant all begin with the quality of this tanning.

[What architecture and leather have in common]

◎ The foundation in architecture: Invisible from above ground, yet it determines the "strength" to withstand the building's own weight and earthquakes.

◎ Tanning in leather: Hard to discern from the finished product even for professionals, yet it determines everything about the leather: its "durability," "softness" and "scent."

■ Why does "tanning" shape the aging to come?

Fine architecture gains dignity as the years go by. Likewise with leather goods, the greatest pleasure lies in the "patina (aging)" by which the leather develops a sheen and molds to your hand the more you use it.

But the beauty of this aging is precisely the important "work" in which the result of the foundational process, "what kind of tanning was done," appears directly.

■ The artisan's "subtraction" creates true dignity

Compared with ordinary cowhide and the like, tanning exotic leathers requires delicate handling and high standards of quality control and finishing technique. This is because the "unique beauty (scale patterns and grain)" that bears witness to crocodiles, snakes and elephants having lived in the wild must not be damaged, but rather brought out to the fullest.

Excess fat and dirt in the raw hide are washed away again and again. Based on precise calculations, the tanning agents are made to penetrate deep into the fibers.

How much passion can be poured into this thorough process of subtraction that is "invisible" in the finished product? That is the decisive difference between tanneries regarded as prestigious and mass-production factories.

Vivid dyeing, a texture that molds to the hand, and the robustness to withstand use: all of these can exist only on top of the solid foundation called "tanning," finished by artisans in work that is literally gritty, yet carried out with great pride.

■ Is what you hold built on a genuine "foundation"?

The next time you pick up your favorite leather wallet or bag, please take a moment to reflect on "this theme." The "foundation" called "tanning," hidden beneath the surface, is the one thing that can never be faked.

Genuine dignity that grows more cherished with time, maturing into a vintage piece that is yours alone.

It is proof of a "foundation" built by artisans who allowed no compromise whatsoever.

Be careful with products whose leather is of "unknown origin"!

As the choice of a grown-up who knows the real thing, I sincerely hope you will choose "leather goods built up from the foundation."
