The thirteenth time trapped in the stone prison, the boy knew Tao Ning/was changed, and Chi You showed his ambition

(4) Tao Ning's frank speech can quickly shorten the distance between him and the people he thinks are interested, and Xiao Gong, who is also simple and innocent, naturally quickly dispels his guard and becomes a friend with whom he talks about everything. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Two people in the same situation, regardless of their age, call each other brothers, and tell each other their experiences, which can be regarded as a relief from loneliness and relief from anxiety in this dark and imprisoned place.

Through the conversation with Tao Ning, Gong has gained some insight.

To talk about the origin of this ancient human pottery, it is nothing more than a coincidence.

In the fire, the ancients stumbled upon the secret that mud was a kind of clay suitable for pottery, and after being roasted by fire, it became hard and would not soften or deform in water. So I found this clay kneaded into a suitable shape, and then burned and shaped, used to hold food, etc., this is the source of pottery, although its raw materials are rough and simple to work, but it can be called an ancient technological revolution.

Pottery is the first invention of Tao Ning's ethnic group - Shennong's Yandi tribe, passed to Tao Ning's generation I don't know how many generations, this technology is strictly confidential, and people who are not confirmed to be inheritable are not allowed to study.

Tao Ning has been obsessed with pottery since he was a child, and after a long period of unremitting research, he added an extra layer of washing before the process of wet clay, shaping, drying and firing. It is to wash and filter the clay required for pottery with water, and the clay made by this processing is more delicate and soft, and the pottery fired is much tighter than before. Not only that, he also improved the method of clay shaping, from the original overall kneading to first kneading the clay into clay strips, and then using clay strips to shape and connect into various shapes of vessels, which virtually reduced the difficulty of shaping and increased the moldable shape.

Tao Ning's enterprising character is destined to not end the road of exploration, before being captured by the Yu people, he wanted to go out to the wilderness to find better pottery clay and pottery recipes, but unfortunately became a prisoner of other tribes, and was enslaved and forced to make pottery for others.

He didn't know that there was great luck hidden in misfortune, but he unexpectedly fulfilled his wish. The people of the Yu nationality live in the cave, in order to prevent Ning from escaping, they burn pottery in the cave, and this unique firing environment actually makes the obsessed Ning realize a set of excellent pottery methods, which can not but be said to be a rare opportunity in the dark.

Originally, the original pottery was made by burning dry clay figurines in firewood and grass in the wild. Nowadays, pottery is fired in a rock cave, and although it is still burned on the ground, the cave is relatively closed, and the firing environment has quietly changed, as if forming a natural kiln. This unique confined environment gives the fired pottery a rare compact and fine texture, and in addition to being harder than before, the surface of the pottery has an unprecedented layer of fineness.

After pondering for a long time, Tao Ning looked up to the sky and laughed, and he thought that he had finally found the key to firing better pottery -- the temperature of fire, which was much higher in this closed cave than in the wild. At the same time, the idea of a kiln for firing pottery was already taking shape.
