LEATHERCRAFT 3

• Tanning


  The process by which pelts, skin, and hides are smoothened and made pliable so that they will be ready for use
• Tannery


  • The place where the animal skins are processed chemically to produce leather material
• Sources of pelts


  • Skins (small-sized animals)
  • Hides (large-sized animals)
  • Kips (undersized animals like lizards and snakes)
• Kinds and condition of pelts

  • Green Pelts
  • Green Salted
  • Dry Salted
  • Dried
• Curing or dressing

  1. Removal of all flesh hair and foreign particles

• Tanning

  Treating the skins and hides of animals to produce leather
• Methods of tanning

  • Vegetable tanning
  • Chrome tanning
  • Fur method
• Vegetable tanning


  Uses tannins, which occur naturally in the bark and leaves of many plants, to bind to the collagen proteins in the hide and coat them
• Chrome tanning


  Uses chemicals like chromium, known as the most efficient and effective tanning agent
• Fur method


  The easiest tanning process because the hair of the skin is preserved as a decoration on the leather
• Vegetable tanning materials

  • Oak bark, chestnut, red owl, hemlock, mangrove
• Vegetable tanning is a very slow process that requires several months to finish a tanned leather
• Chrome tanning is faster than vegetable tanning (less than a day for this part of the process) and produces stretchable leather
• The fur method involves applying a chemical compound (grease) only on the flesh side and never on the grain side to preserve the hair
• Happy face or sad face statements


  • Dry salted comes directly from animals and is brought immediately to the tannery (sad face)
  • Green Pelts come directly from animals and are brought immediately to the tannery (happy face)
  • The fur method is considered the easiest tanning process because the hair of the skin is preserved as a decoration on the leather (happy face)
  • Green Pelts come directly from animals and are brought immediately to the tannery (happy face)
• Fur Method


  The easiest tanning process because the hair of the skin is preserved as a decoration on the leather. The application of the chemical compound (grease) is only on the flesh side and never at all on the grain side because it will destroy the hair. The application of the compound is done three times using a brush.
• Dry salted


  Comes directly from animals and is brought immediately to the tannery
• Green Pelts


  Come directly from animals and are brought immediately to the tannery
• The fur method is considered the easiest tanning process because the hair of the skin is preserved as a decoration on the leather
• Green Pelts come directly from animals and are brought immediately to the tannery
• Vegetable tanning


  Done with the use of chemicals like chromium, long been regarded as the most efficient and effective tanning agent
• Dried after the fresh pelt has been stretched on board and dried
• Vegetable tanning is considered the earliest method of tanning leather
• Chrome tanning


  Done with the use of chemicals like chromium, long been regarded as the most efficient and effective tanning agent
• Kips


  Obtained from large-sized animals such as cows, horses, carabao, and others
• Hides


  Pelts of undersized animals like lizards and snakes
