The origin of distilled spirits is distillation is a technique in which an individual would vaporize and then re-condenses a liquid in order to separate and purify its constituent parts. this originated from Arabian scholars in cordoba, Damascus, and Baghdad. these scholars were building on knowledge from Greek, Indian, and Persian sources in other fields such as astronomy, mathematics, and medicine, and they also refined and popularized the technique of distillation that led to the creation of new drinks.
By using selective boiling and condensation, distillation, also known as traditional distillation, is the process of removing the constituents or compounds from a liquid mixture. The process of heating solid materials to create gaseous products is known as dry distillation (which may condense into liquids or solids).
Dry distillation, which is not covered in this article, may involve chemical alterations such as destructive distillation or crack. The separation produced by distillation might be nearly perfect (components are nearly pure), or it can be partial (the concentration of some components in the mixture is increased).
In either scenario, the mechanism takes advantage of variations in the components of the mixture's relative volatility. Distillation is a unit operation of almost universal significance in industrial applications, although it is a physical separation process, not a chemical one.

Silk production
---------------------
A moth lays 500 or so eggs and then dies
Baby worms hatch from the eggs are fed mulberry leaves for one month until they are fat
The worms spin cocoons
The cocoons are steamed to kill the growing moth inside
The cocoons are rinsed in hot water to loosen the threads
Women would unwind the cocoons and then combine six or so fibers into silk threads
The threads are woven into cloth
The cloth is then pounded to make it softer
Why it was valuable to the Chinese
-------------------------------------------------
Silk cloth was extremely valuable in Ancient China. Wearing silk was an important status symbol. At first, only members of the royal family were allowed to wear silk. Later, silk clothing was restricted to only the noble class. Merchants and peasants were not allowed to wear silk. Silk was even used as money during some Ancient Chinese dynasties.
Why it was secret
-------------------------
Silk became a prized export for the Chinese. Nobles and kings of foreign lands desired silk and would pay high prices for the cloth. The emperors of China wanted to keep the process for making silk a secret. Anyone caught telling the secret or taking silkworms out of China was put to death.
Hope all this helps :)
