Chapter 192 Tanning Leather (3)
In the primitive era when production conditions were relatively backward, animal skins were the main material for daily wear and decoration, and people began to study the technology of processing animal skins very early.
Freshly peeled animal skins, if not processed, will have grease and animal odors and will be very stiff, making them completely unsuitable for daily use.
Therefore, if you want to get soft and warm animal skins, you must nitrate the "raw hides", and the technical requirements are very strict, otherwise it will be unusable.
Generally speaking, animal hides are usually tanned by oil tanning and smoking, which is also the main method used by primitive humans to process animal hides, as confirmed by archaeologists.
As a wilderness survival anchor, Xia Tian has extensive knowledge in this area and is very skilled in the movements.
The first step in tanning leather is to clean the hide.
Fur Fur, one side is skin and the other side is hair.
The fur part does not need to be processed too much. Si Ye's movements when skinning are very clean and neat. Except for a very small amount of blood stuck on it, the rest of the body is intact and clean.
The main processing object is the skin on the other side connected to the meat, which is also the "protagonist" of the tanning process.
Because the fresh animal skin had just been peeled off from the exotic beast, it still had fresh blood and various tissues on it. It was necessary to use a stone knife to remove the useless adhesion substances bit by bit, and then clean the blood stains.
This process requires patience and carefulness, and it cannot be delayed too long, otherwise the fur will begin to harden, shrink and deform, and all the preparations for tanning will be wasted.
"This part of the tissue must be completely scraped off, leaving no trace, otherwise it will affect the final tanning effect and the storage time of the fur." Xia Tian was in the kitchen, doing her work while communicating with Si Ye who was grinding stones in the cave.
This was not only because she was open about the skills she knew, but also because of the requirements of the system -
She really wasn't sure what achievements needed to be achieved to light up the civilization tree, nor did she know what the requirements were, so she could only make preparations and try to teach him what she knew whenever she had the chance.
Si Ye is a person who loves to learn and has strong hands-on skills. As long as you watch her demonstrate it once, you will basically be able to learn it. At that time, you will also be able to verify what kind of evaluation criteria this live broadcast system uses to judge the achievements of civilization.
Although many of the audience in the live broadcast room have never seen real fur, or their performance in their studies and work is average, they are surprisingly studious here.
[I understand. You must be patient when doing this. You must clean up all the tissues above.]
How much tilt should I use for this technique? Also, the strength should be controlled.
I think I'm a little worried about scratching the hide.
[So Xia Xia seems to have used the blunt side of the stone knife to make it, probably to protect the fur]
This attitude is even more serious and hardworking than when I took the entrance exam myself.
Xia Tian was a little amused but still patiently answered various questions and reminded Si Ye of some precautions.
"The stone knife is tilted at a certain angle to make it easier to apply force. There are no special requirements for this. Of course, the stone knife can't be too sharp, otherwise it will scratch the fur. And you must be patient..."
