Chapter 648 Animation

    In fact, Zhao Hao is not too worried about leaking secrets.

    After all, cement is not coal, and it is useless to know the formula. The key to its production lies in the exact firing temperature and the correct ratio of raw materials.

    If these two things are not done well, the quality of the burned cement will be very poor, and the building will even collapse on its own.

    It was not until the mid-19th century that people summed up these two valuable experiences and figured out the most suitable temperature and the most suitable ratio of raw materials.

    The latter is easier to say. In the era before infrared thermometers, the former told you the appropriate temperature, but you still didn¡¯t count it.

    So how to determine the temperature in this era?  Zhao Hao's answer is to look at the fire.

    The flame that first started to glow was 500 degrees, crimson at 600 degrees, crimson at 700 degrees, cherry red at 800 degrees, cherry color at 1000 degrees

    When the fire is so white-hot that people dare not look directly at it, it has reached 1,400 degrees!

    Apart from him, only Hua Boxhen and a few technical backbones know what kind of fire color should be maintained in the furnace, which makes it difficult for others to steal the secrets.

    Well, actually the fire needs to be kept white hot, which is one thousand four hundred degrees.  So using firewood is totally out of the question.

    Fortunately, there is coal in Xishan, but the quality of the coal is not good, and it can barely burn red.  If it is crushed into coal powder, it can only be burned into cherry red.

    When Zhao Hao stayed in Xishan for so long, he spent most of his time trying to raise the furnace temperature.

    Later, I listened to Hua Boxhen¡¯s suggestion, adopted the structure of Wuxi brick kiln, and built a high kiln with automatic air suction. With the continuous pulling of several bellows, the furnace temperature was finally reached.

    By the way, even Hua Boxhen didn¡¯t know that refractory bricks are needed to build a high kiln.  Because the bricks fired on the island are kaolin clay unique to Xishan, they are refractory bricks.

    ¡°But bricks made from ordinary clay elsewhere cannot withstand the temperature in high kilns

    No way, who made the cement islandoh no, the Xishan Island is so considerate and has everything you need?

    ¡°And Xishan Island is still an island in a lake, so it is easier to keep it secret.

    ??~~

    After visiting the cement factory, Mr. Zhao¡¯s hair was already white when he came out.

    He took off his sunglasses from the bridge of his nose, took out his handkerchief and wiped off the layer of dust on them.  In order to avoid becoming a panda, Zhao Hao resolutely rejected Hua Boxhen's arrangement and will not inspect the 'Jiangnan Coal Field' today.

    When we went back, it was still the same gunner camp. The original camp headquarters was completely changed into the residence where Mr. Zhao lived when he came to the island, and it has been completely changed.

    The original dilapidated wooden house was completely demolished and rebuilt into a brand new brick house. The outside was painted with white dust, and the walls were hung with black tiles. The yard was filled with cement, the wellhead was sealed, and a suction pump was installed.

    Oh, by the way, it¡¯s called Drainage King.

    Qiaoqiao and Secretary Ma have lived on the island and know how dirty the cement plant is.  The two of them wisely did not follow, and came directly to tidy up the residence, boil water and wait for Zhao Hao to return.

    Seeing that he entered the yard in disgrace, the two women made fun of him while helping him wash his hair and bathe.

    By the time Mr. Zhao cleaned himself up again, it was already dark.

    Zhao Hao asked Xu Yuanchun and Xiaozhi to come over for dinner.

    He originally planned to ask Xu Yuanchun and Xu Kun what they talked about, but thought it would affect his appetite too much, so he wisely did not ask.

    I thought in my heart that this guy would definitely ask for help anyway, and we would just talk about it then.

    After dinner, when Zhao Hao was about to see off his guests, Xu Yuanchun suddenly knelt on the ground.

    Mr. Zhao said to his heart, "Here we come, although we are late, we are here."

    "Teacher, please accept me as a disciple!" Unexpectedly, this guy didn't mention his second uncle at all, but talked about becoming a disciple again.

    "Uh" Mr. Zhao was a little confused, wondering why the young people of this generation don't act according to common sense?

    He had no choice but to ask the persistent Xu Yuanchun: "What do you want to learn? You are so persistent."

    "Teacher, I want to learn this." Xu Yuanchun took out the physics book from his sleeve, turned to the middle page, and gave it to Zhao Hao with both hands.

    Mr. Zhao took it and took a look at it under the light. He saw that the title of this page was "Scam".  This is a small experiment he gave to explain how people see.

    It is to use the principle of "visual residue" to draw the character's decomposed movements on a disk, and then use a disk with a window to cover the previous one.  By turning the rear disc in this way, you can see the characters moving through the window of the front disc.

    "You want to learn animation?" Mr. Zhao looked at Xu Yuanchun in surprise. He didn't expect that his popular science booklet would actually help the grandson of the former chief minister to awaken.Incredible dead house properties.

    It can be said to be the first dead house on earth.

    "Animation that's right, it's a painting that can move!" Xu Yuanchun nodded excitedly, took out a book from his sleeves, handed it to Zhao Hao with both hands, and said: "Teacher, please look, this is what the students did according to your teachings."  The first 'flipper book' to come out!"

    "Oh, animation book?" Zhao Hao took it and flipped through a few pages, seeing that the pictures on each page were coherent.  He held all the pages in his right hand and released his fingers little by little.

    Amidst the sound of turning the book, the characters in the book started to move.

    What he painted was actually the scene when he was in Yuyuantan, taking a hot air balloon to the sky.

    From the time the hot air balloon took off to the distance, it was as lifelike as if it were yesterday again.

    But it¡¯s not just a reappearance, because after the hot air balloon took off, a flying sky and a phoenix appeared accompanying it. It was obvious that Xu Yuanchun was doing artistic processing again.

    Zhao Hao finished reading it quickly and couldn't help but praise: "This is awesome."

    Xu Yuanchun was immediately elated. He took out a round copper box from his bag and continued to offer treasures.

    After opening it, there was a trick he made inside.  But it¡¯s different from what Zhao Hao introduced.

    He put a circle of cardboard vertically on a rotatable disk.  Then I drew on the inside of the paper tape and made thin vertical holes on the paper tape.

    Zhao Hao turned the disk, but also because of the 'visual residue', the vertical holes seemed to be motionless.  Through the vertical hole, you can see the heroic figure of a girl in red skiing on the snow. I don¡¯t know who the prototype is.

    This is much more three-dimensional and vivid than the flat surface, it really feels like watching a cartoon.

    "Niu Boyi!" Mr. Zhao gave two thumbs up.

    "There's more!" Hearing Zhao Hao's praise, Xu Yuanchun's morale was greatly boosted, and he continued to take out a round glass plate from the copper box.

    As I said before, Western glass has been introduced to the Ming Dynasty long ago, and the Ming Dynasty royal family can also produce glass, but they all have one problem, it is expensive But he is the grandson of Xu Huating.

    Zhao Hao saw that he had drawn the storyboard on the glass this time, and also covered most of it with a paper shell, leaving only one blank frame.

    There is a round hole in the center of the glass disk, with a wooden rod inserted as a shaft.

    Then Xu Yuanchun put it up, brought it to the candle, and asked Xiaozhi to help him turn the glass plate. A slightly blurry horse was projected on the white wall opposite, but its running movements were very smooth!

    "Damn it, the trick projector!" Mr. Zhao shouted excitedly: "You are such a fucking genius!"

    Xu Weizhi was also very excited when he saw it. When his brain became hot, he gritted his teeth and lifted up his robe, knelt down side by side with Xu Yuanchun and said:

    ¡°Teacher, please accept me as a disciple, I also want to learn animation!¡±
