Tanners Taroudant |

The
Tanners in Taroudant are very gifted artisans
that have been making wonderful leather
products for decades, the tannery place
just outside bab taghrount offer so many
leather goods, such as rugs, shoes, bags,
sandals, and decor items, they are doing
their process in a very traditional and
authentic way.
The
aim of tanning the leather is to permanently
halt that process by removing most of the
fat and mineral parts of the skin while
retaining and strengthening the remaining
connective tissues, the tanning process
cannot be immediately begun, the skin must
be temporarily preserved, this curing can
be done in a variety of ways, but generally
involves salting and drying, processing
a skin into leather takes many steps, each
of which affects the physical and chemical
properties of the finished material, the
actual tanning does not happen until the
skin has been prepared by soaking, dehairing,
fleshing, scudding, deliming, and bating.
The
first step, soaking, removes the water-soluble
minerals and salts, washes off dirt, blood,
and dung, and rehydrates the dried skins.
Next, the leather is prepared for removal
of the hair, or dehairing. this is accomplished
either by controlled rotting (sweating)
or by soaking the skin in a suspension of
lime, the addition of sodium sulfide in
an aqueous solution significantly speeded
up this process, most of these dehairing
processes raising the alkalinity of the
leather, though this is most pronounced
in modern leather manufacture.

Lime and sodium
sulphide plump up the fibers and begin to dissolve the
keratin of the hair and epidermis while leaving the
collagen in the derma intact. Once the keratin is loosened,
the hair and epidermis are mechanically removed with
a blunt knife, modern leather production adds strong
alkalis to the bath to actually dissolve the hair root
and epidermis. The next step is directed at the flesh
side of the skin. Fleshing cleans and levels the lower
side of the skin, smoothing out natural irregularities
in thickness and removing unwanted hypodermal tissue,
a process known as scudding cleans any remaining hair
and dirt from the grain side with a blunt knife.
These preliminary
steps are intended to remove all of the undesirable
elements of the skin. They do not, however, address
the principle problems of leather preservation - the
propensity of the skin to putrefy when wet and to harden
when dried. Several methods exist of treating skins
to render them imputrescible and supple; the main categories
are vegetable, mineral, and oil processes. Extensively
used in bookbinding for centuries, vegetable tanning
relies on the properties of a group of complex substances
known as tannins derived from plant matter. Mineral
processes like alum tawing and oil processes such as
brain tanning and chamoising are also historically significant,
though used infrequently in bookbinding.
