It is sad to ask for it, to give it up, to give it up without hesitation. According to Anya's meaning, no matter which possibility it is, Sima Cheng is destined to be a poor person.

The production scale of bricks and tiles is large, and the output and quality have been improved. The size and shape of the bricks and tiles are different from the previous generation, and the pattern tiles are rare, and most of them are plain tiles. The cloud pattern on the tile is gradually replaced by a lotus pattern.

Auspicious writing is still popular, and there are wadangs with the year printed on them. Glazed tiles are used, and a light green glaze is applied.

In addition to rectangular plain bricks and Jomon bricks, there are also two types of large sculpture bricks for decoration. One of them is a beast face with a fierce expression, a huge mouth and beard, and angry fangs, which is vivid and magnificent.

"Jiuquan Yanshou County Nanshan out of the spring water, as big as a basket, into the ditch, the water has fat such as gravy, take the vessel, the beginning of yellow, after the black such as condensation paste, but extremely bright, and the paste is no different, the plaster car and the water tank is very good, the other side of the people call the stone paint. Water and fertilizer are also there, and the water of Gaonu County is also there. ”

It is recorded that in the country of Qiuci, "there are people like ointment in the northwest mountains, which flow out into the river, and go into the ground for several miles, and it is very smelly." People regard this oil as a panacea, believing that "those who take it can be rehabilitated, and the sick will be cured if they take it".

The aliens besieged Jiuquan, the people of Jiuquan used oil as fuel, burned the Turkic siege equipment, and the Turks put out the fire with water, not only did the fire not be extinguished, but burned more and more, and the Turkic army was defeated. In this way, Jiuquan City was not occupied by the Turkic army.

After the successful digging of the gas well, how to extract gas to facilitate the use, the book describes the gas recovery method of "boiling salt on the well with a basin cover" in the Linqiongran gas well. The earliest gas production device in the Ming Dynasty was the "basin", that is, the iron basin for boiling salt, which was covered on the well, so that the rising gas at the bottom of the well would not spread and overflow.

Then "throw bamboo and wood to make fire". This plays a role in gas recovery and the utilization of thermal energy, thus successfully developing shallow natural gas. In addition, people have also mastered the technology of collecting and storing natural gas in bamboo tubes.

Ranqi is not only widely used, but also becomes an important material for literary works. Guo Pu wrote in his "Salt Pond Fu": "Rong Rong is in the west, and the fire well is good at Bapu."

However, gas wells are limited to Bashu and a few areas in Shaanxi. Later, the area where the seedlings were found expanded. Not only did they find oil, but they also found gas spewing out of the ground and burning.

It is worth mentioning that at that time, Fan Yang was under the jurisdiction of the country, and Ran Qi was found here and used for cooking, which is very remarkable. Soon, natural gas was found in the area.

Although at this time, they could not get rid of the shackles of mysticism and regarded oil and natural gas as "foreign substances", but they had a deeper understanding of it and boldly used these "foreign substances" in many fields of production and life.

In addition to the original hemp and bark, it has been extended to make paper with mulberry and rattan bark. For example, white linen paper and jute paper used for writing scriptures, leather paper made of wolfberry bark, rattan paper made of rattan fiber, mulberry root paper made of mulberry bark, straw paper made of straw, etc.

Northerners also use Tsubaki bark to make paper. They boiled and peeled the bark, and although it was very hard, it was very profitable; If you can make paper yourself, the benefits will be even greater. The purpose of farmers in the north to plant oak trees is to make paper; Moreover, boiling and peeling bark is an important process in papermaking.

The hemp paper is made of rags, but it is white and inked, and it is of good quality and low price, and it can be rolled after being written. If the writing material is still used in silk and simplicity. Because of the large amount of white, smooth and square paper that can be made, people no longer need to use expensive silk and bulky slips, and gradually get used to writing on paper, and finally completely eliminate slips.

Archaeological excavations have shown that although the documents produced in the tombs or ruins are mostly paper, there are still Jane unearthed from time to time.

However, since the Eastern Jin Dynasty, there are no longer simple documents, and all paper is used. In the past, when writing on slips, pieces of slips were tied up with strips of leather or rope, connected into a long string (book), and then rolled into a large bundle.

When writing on paper, a piece of paper is glued together with paste and rolled up with a wooden scroll, so that a roll of paper can hold several large bundles of simple books, which is light and practical, thus causing the evolution of the form of the book.

In the past, a book written in a brochure required two people to lift, but now it can be easily carried in a pocket.

The widespread use of paper in Chinese society has effectively promoted the rapid growth of books and documents and the spread of science and culture. On the contrary, the development of scientific culture and the book industry requires the creation of more and better paper.

One of the most important processing technologies is surface coating, in which white mineral fines are brushed on the paper with adhesive or starch paste and then calendered. In this way, it can not only increase the whiteness and smoothness of the paper, but also reduce the light transmittance, so that the paper surface is tight and the ink absorption is good.

Another technology for paper processing is the so-called "Huangzhi" method.

"Where you beat paper, if you want to live, it is strong, and it is especially suitable for decoration. After the tiller is cooked, it is pounded and boiled, the cloth bag is pressed, and the re-pounding is boiled, where three pounds and three boils, and the pure juice is added, the province is four times, and it is clear and clean. Write a book through the summer and then into the decoration, and the sewing is not unraveling. The new writer must be sewn and ironed with an iron. No, if you enter, it will be scattered. ”

The purpose of such a set of decoration methods is not only to dye, but more importantly, to use the medicinal power of yellow tiller to prevent insects. In addition, the book also describes the method of using the "orpiment cure" to prevent insect damage.

At that time, the porcelain kilns in various places used the local porcelain clay as the raw material for billet making, and the Yue kiln may have consciously selected the porcelain clay with high iron and titanium content as the blank, so that the tire was burned gray, which played a role in setting off the glaze, and made the glaze green with gray, and the tone was relatively quiet.

The lime glaze made of limestone and porcelain clay is characterized by good luster and high transparency. The black glaze is prepared with purple gold clay with a high iron content.

Later, black porcelain and white porcelain were developed. The production of white porcelain, the early white porcelain, the fetal material has been refined, relatively fine white, the glaze layer is thin and moist, milky white, but it is still generally blue, and some places with thick glaze layer are cyan.

On the basis of tradition, there has been an improvement, its use is expanding day by day, the variety of colors has increased, and the glazing method has also increased, or yellow ground plus green color, or white ground plus green color, or yellow, green, brown three colors are used together.

From monochrome glaze to multi-color glaze has taken a step forward, the art of pottery and sculpture is not very developed, the production is simple, the form is dull, and the number is not much. The art of pottery and sculpture breaks through the rigid style and pays attention to the depiction of the demeanor, so the shape is beautiful.

In the textile industry, the cloth woven from hemp was improved by Ma Jun, and the variety and quality were improved. At that time, in addition to hemp paper, the paper industry also used rattan to make "rattan horn paper". Paper has been able to make snow-white paper and five-color flower paper, and by the Southern Dynasties, bamboo slips and silk brocade were completely replaced.

The porcelain industry has also made great strides in manufacturing technology and has spread widely in the southern region. For example, Zhejiang has formed Yue kiln, Ou kiln, Wuzhou kiln and Deqing kiln.

In terms of tea making, due to the Jin Dynasty's habit of drinking tea and advocating tea instead of wine, the demand increased, and the planting area progressed to the southeast coast.

It is precisely because Sima Cheng rarely goes out to show his head that the rumors about him in Luojing City will intensify.
