2. LEATHER
• It is a durable and flexible material created via
the tanning of putrescible animal raw
hide and skin, primarily cattle hide.
• It is animal skin that has been processed to
retain its flexibility, toughness, and waterproof
nature.
3. LEATHER
• The natural surface of leather is similar to
wood grain, each has its own distinct
characteristics. These unique features exude
authenticity and accentuate the landscape of
each individual hide.
5. HISTORY
• Prehistoric people wrapped animal skins
around their bodies for warmth.
• Romans used leather for shoes and tunics as
well as for breastplates and shields. In fact,
the first recorded tanning guild was formed in
the Roman Empire.
6. HISTORY
• Ancient Hebrews are credited with inventing
the first tanning process using oak bark. The
American Indians used fish oil for the same
purpose. American colonists found that plants
such as the hemlock and chest-nut trees could
also be used for tanning.
7. HISTORY
• In the 19th century, machines were developed
to perform these processes and an American
chemist developed a tanning method using
chromium salts that cut the processing time
from weeks or months to just a few hours.
