How did the fresh sheep intestines become strings worth thousands of dollars after drying?

This is sheep intestines bought from livestock slaughterhouses. In the next two months, they will be polished into musical instrument strings worth thousands of dollars by string manufacturers.

First of all, in order to make the sausage softer before making, the guitarist will soak the sausage in cold water for two days, and then carefully scrape off the fatty mucosa on the surface of the sausage with bamboo strips. Next, soak the fat-scraped sausage in the nail clipper and squeeze out the dirty things with a ring. Until the texture of sausage becomes transparent and clean, a 20-meter-long sausage can be cut into strips with different widths with this special long knife. The thinner bars are used to make high-pitched strings with clear timbre, and the thicker bars are used to make low-pitched strings with stable timbre.

Secondly, next, in order to prevent the sheep intestines from oxidation and blackening, the stringing workers should soak the sheep intestines cut into seven meters in bleached water for three days, then use seven thin sheep intestines as a group to make high-pitched strings, and the thickest bass long string needs at most 120 thick sheep intestines, then put the two ends of the sheep intestines on the traditional stringing machine respectively, and then grind all the sheep intestines into a larger one by constantly rotating the reel. In this process, due to the rapid evaporation of water in the sheep intestines, guitarists need to disassemble the sheep intestines constantly, so that the sheep intestines can be ground into the appropriate texture under the appropriate humidity, and then put the glued sheep intestines on the shelf to dry.

Thirdly, in the whole air-drying cycle, in order to reduce the diameter of the intestine while maintaining the length and looseness of the intestine, the long strings need to be twisted repeatedly according to the air-drying condition of the intestine until the intestine is completely air-dried and the texture becomes firm and yellow, then the rough particles on the surface of the long strings are polished off with special horse hair, and then the long strings are repeatedly trimmed with towels and hay soaked in olive oil until each long string reaches the factory standard. You can cut high-pitched strings into specified lengths according to the requirements of different musical instruments, while long bass strings need to be covered with a thin layer of silver wire, the density of which is seven times that of long strings. This will not only improve the toughness of long strings, but also add more heavy sound effects to long strings. Finally, after decorating both ends of the long rope with red silk thread, it can be packaged and sold.
