Shaking his head helplessly, he walked out of the small workshop, but he was angry and said aggrievedly: "This is what you said!?" ”

Liu Feng waited to explain it, thought about how to explain it clearly, smiled bitterly, left the workshop quickly, and walked towards the mansion. （）

Ulan also took it when he saw it, followed behind Liu Feng, and returned to the house.

However, in the next few days, Liu Feng was busy in the firing camp, firing his tiles, after a few days of changes to the production line, changes to the porcelain clay and porcelain enamel, etc., the fired tiles can also be fired out of several types of tiles.

Later generations of ceramic tiles, according to the different raw materials are divided into: ceramic bricks and porcelain tiles, ceramic bricks are fired using clay so the water absorption rate is higher, the general surface needs to be glazed and then fired, belongs to a kind of glazed bricks.

The most widely used porcelain tile in the ceramic tile industry is made of porcelain clay, which is fired with porcelain clay, in order to make it decorative, the glaze will be added to the high temperature and high pressure firing, so that the material is dense, high hardness, high strength, low water absorption, high pressure resistance. Most ceramic tile products in the ceramic market belong to porcelain tiles.

According to the different production processes, it is divided into: full-body bricks, polished bricks, fully glazed antique bricks, microcrystalline stone.

At this time, Liu Feng could only fire pottery bricks, although compared with porcelain bricks, the process is a big difference, but in this era, Liu Feng's pottery bricks are also high-quality.

In the selection of porcelain clay, after many experiments, the proportion of clay quartz sand feldspar has gradually mastered and perfected, of course, these are only known to Liu Feng and Zhao Xuewei and several masters.

During the development of ceramic tiles, Liu Feng also popularized the material characteristics of various raw materials, in terms of the raw materials of ceramic tiles, the plasticity of clay, the barrenness of quartz sand, and the solubility of feldspar.

Let these craftsmen no longer rely purely on experience to modulate the proportion of porcelain clay, but to experiment in a scientific way.

When Liu Feng used the language of scientific data to explain the characteristics of various raw materials to Zhao Xuewei and the bows and arrows, he was despised because the craftsmen could not understand the physical characteristics he said.

Zhaozhi in the crowd cheered him and said: "What the general said is that the firing of ceramic tiles is very different from the firing of porcelain, and it must take into account two aspects: strength and hardness. ”

"If quartz is the skeleton of the tile, clay is the meridian of the tile, and feldspar is the blood that connects the two. After mixing clay with an appropriate amount of water, it forms a mud mass, which is deformed but not cracked under the action of a certain external force, and can still maintain its shape when the external force is removed. These are the properties of the respective materials. ”

The people who can enter the circle of development are all masters of porcelain firing, how can they not understand such a truth, but Liu Feng described the characteristics of various raw materials in porcelain clay, which made them a little confused.

And Zhao Zhi explained such a metaphor, and everyone nodded their heads.

Half a month before the spring ploughing, Liu Feng almost stayed in the burning camp, did not leave, and put on a look that he would never give up if he did not fire tiles.

Fortunately, everyone lived up to their mission, and after everyone's collective efforts, Liu Feng was also among them, opening his golden finger and establishing a ball mill for porcelain clay grinding and a conveyor belt for the production line, but these ancient machinery without mechanized power and ancient machinery were running under the condition of animal power and water power.

Ceramic tiles can be fired and produced, but the output price is an important factor limiting its promotion, Liu Feng in order to solve the problem of production volume, in addition to subdividing the types of craftsmen in the firing camp, but also strengthen the use of mechanization on the production line.

There are more and more mechanized applications on the production line, and there are more and more smiles on Liu Feng's face, but the craftsmen in the firing camp are not as good as Liu Feng, and they are happy with the manpower-saving machinery.

The day after installing some machinery, Liu Feng gathered a group of middle and senior craftsmen and Zhao's father and daughter, surrounded the conveyor belt ball mill mold machine, etc., simple but can save manpower, whispering, and the words of resentment in the words made Liu Feng a little surprised.

Liu Feng's face sank when he heard this, he stepped forward and said in a deep voice: "What are you discussing, why don't you dare to teach someone to hear?" ”

When a group of craftsmen heard this, they saw Liu Feng's gloomy face, and lowered their heads in fear, until Zhao Xuewei was not afraid of him, she had to stand up when she saw this, but she also wanted to stop talking, and finally plucked up the courage to say: "General, arranging so many utensils, is it to streamline the craftsmen?" ”

Liu Fengren glanced at him, saw that he was looking at himself with a look of hope, and suddenly understood, and said with a smile: "Where do you say this!" I'm still understaffed in the camp! How can the craftsmen be streamlined! ”

"That ......," Zhao Xuewei said earnestly,

Without waiting for her to say anything, Liu Feng interrupted: "The demand for ceramic tiles and porcelain will increase more and more, but relying on manual work, it is far from being able to meet our needs, so we must try to develop and use better production tools!" I assure you that the Shogun Camp will not downsize its craftsmen because of this! ”

When everyone heard this, they all nodded happily.

The reason why they are somewhat resistant to the emergence of production equipment is because the emergence of these tools has made most craftsmen lose their jobs, such as the emergence of ball mills, which has turned an intermediate craftsman who grinds porcelain clay and porcelain stone into a junior craftsman who guards the ball mill, or even a trainee craftsman.

How can these craftsmen not be vigilant in their hearts, not to mention the treatment of the burning camp, which is nowhere to be found at the moment, take the intermediate craftsmen as an example, their monthly reward can reach more than fifteen taels per month, such a good treatment, so that they are reluctant to abandon the burning camp and go.

In the evaluation of ancient buildings and great historical projects, people will always have such a sentence, such a canal, a certain Great Wall, and a certain tower embody the wisdom and great creativity of the working people.

And Liu Feng is to give full play to the wisdom and great creativity of the working people, after more than a month of research and development, the burning camp of Liu's tiles, can finally be published, Liu Feng named "gold and stone bricks", and the first time in the five gods of the restaurant inside and outside the lay.

The one-foot square porcelain floor tiles, the glaze is smooth and translucent, and the five restaurants are laid differently.

Among them, the ordinary solid color porcelain enamel tiles, laid on the floor, bright and clean, suddenly compared to the wooden floor, not to mention the floor paved with green bricks.

The color of the white tiles, Liu Feng remembered Chen Fengming's praise of white porcelain in the Ming Dynasty, "What year is like Lingyan perch, stepping on Qiong Yao to make mud." Ye Ye Baoguang opened the Buddha soil, and the crystal white air pressure Dan ladder. ”

Among them, the main pale gold tile, its full and thick glaze, after polishing, the luster is moving, like jade; Its finely carved textures also have a natural charm, which is not only a tile to be laid, but also a work of art to be admired.
