Soon, ten minutes later, the glass put into the cooling furnace was finally cooled, but when the glass was slowly pushed out of the cooling furnace.

    Wang Bin and the workers present looked very ugly, because the glass in these molds pushed out of the cooling furnace had broken and still broken into slag.

    Obviously, when smelting this furnace of glass, the workers must have ignored something.

    Then Wang Bin immediately picked up some glass slag and looked at it carefully. He found that many black things appeared in the glass of this furnace. Obviously, according to the original data, it is absolutely impossible for these black things to appear in these glasses, which can be seen by the naked eye.

    "Let''s not smelt again. First check the electric furnace to see if there is any problem. I''ll first test these failed products to see if there is a problem in that aspect." after that, Wang Bin took some glass slag to his laboratory to test the glass.

    When the test was completed, Wang Bin found that in these glasses, in addition to the black substances that can be seen by the naked eye, there are more invisible to the naked eye, which can be said to be all over every corner of these glasses.

    Wang Bin also as like as two peas rather baffling the material, but the material elements of black matter are identical to those of special glass. This makes Wang Bin somewhat puzzled. After all, the same materials and smelting processes and processes are alike, but this smelting process will fail somehow, and even the black matter in glass is rather baffling.

    After thinking for a while, Wang Bin didn''t come up with a clue, so he went out of the laboratory. He wanted to see how the workers checked the electric furnace and whether it was due to the electric furnace.

    However, when Wang Bin came to the workshop and conducted a series of tests on the electric furnace with the workers, he found that there was no problem with the electric furnace and all the equipment was very normal, which made Wang Bin even more puzzled.

    At a time when the attack was at a loss, Wang Bin said to the workers, "let''s prepare, restart smelting and see the situation of the second furnace. If the second furnace is still like this, there may be a problem with the materials."

    But in fact, Wang Bin still doesn''t think it''s a matter of materials. After all, the materials used today are the same batch as those used yesterday. It''s not reasonable. There''s no reason why the same materials can be made of the glass stock smelted yesterday, but not today. Can''t the materials be made by date.

    However, when the workers were ready to put quartz sand into the electric furnace, Wang Bin found something different in the electric furnace.

    Before, the temperature in the electric furnace was still relatively high, so Wang Bin and the workers did not find any abnormalities in the electric furnace, but now the electric furnace has completely cooled down, so he found that the original glass stock solution remaining in the electric furnace has completely changed from dark red to black.

    So he immediately said to the workers, "wait!"

    "What''s the matter? Mr. Wang! Have you found the problem?" the workers asked in some confusion.

    Wang Bin nodded and came to the electric melting furnace. He took out some glass slag in the electric melting furnace after natural cooling with pliers. He looked at it carefully. After a long time, he said to the workers: "when you started production this morning, didn''t you clean up the remaining glass slag in the electric melting furnace when you produced glass yesterday?"

    After listening to Wang Bin, a worker asked, "Mr. Wang, do you want to clean the glass slag in the electric furnace?

    It would be a waste of materials to clean up the remaining raw liquid in the electric melting furnace after each smelting. These materials are not cheap, especially those rare materials. "

    After listening to the worker''s words, Wang Bin was speechless. You know, even for ordinary glass, after production, the glass slag in the electric melting furnace also has a great impact on the next production of glass. Before, these workers did not need to clean the electric melting furnace when they were still producing glass crafts and producing a small amount of glass with Tiangong technology, After all, the quality requirements of glass crafts for glass are not so high. Even if there are some defects, they have nothing to do with elegance. Moreover, these defects can be treated in the processing of crafts.

    But now it''s different. They produce special high temperature resistant glass! In the production process, all procedures can not have any problems. If you are not careful, the whole furnace of glass stock solution will be scrapped, as it was this morning, and even affect the subsequent production.

    Therefore, Wang Bin already knows that the problem this time does not appear in materials and equipment, but that the workers did not thoroughly clean the glass furnace before starting today.

    Of course, the workers are also kind. They are afraid that there will be a waste of materials in the smelting process. In addition, when Wang Bin left yesterday, he did not explain clearly to the workers, which led to the smelting failure of this furnace of glass stock solution this morning.

    So he said, "well, I already know the reason. It''s because the electric furnace didn''t clean up completely before starting this morning, but it''s also strange that I didn''t explain it in advance.

    In the future, we must remember the lesson of this time. Don''t ignore the details because of saving materials. In the future, we must clean all the remaining slag in the electric melting furnace after smelting one furnace, and then carry out the smelting of the next furnace.

    At the same time, don''t be afraid to waste materials in production, especially when the first furnace is smelted every morning. After all, there is no way to produce special glass. Otherwise, this furnace of glass this morning is the best lesson.

    Well, everyone is an old worker of Tiangong technology. I don''t want to say anything more. Just be clear in your heart! Let''s start! "

    After that, Wang Bin and the workers began to clean the electric furnace. Soon, the electric furnace was cleaned up with the joint efforts of everyone. Wang Bin allowed the workers to start putting raw materials into the electric furnace and starting the electric furnace.

    When the workers began to put materials into the electric furnace, Wang Bin also stared at the situation in the furnace all the time, for fear of any accident in the smelting process or the appearance of the previous black thing again.

    However, fortunately, during the smelting process of the cleaned electric furnace, there was no accident in the glass stock solution, and there was no wrong color in the red glass stock solution.

    An hour later, today''s second furnace of glass stock solution finally came out of the furnace, and then the workers poured it into the mold and pushed it into the cooling furnace for cooling. However, after pushing the mold into the cooling furnace this time, the workers did not immediately start smelting the glass stock solution, but first cleaned up all the remaining slag in the electric melting furnace, and then waited for the glass in the cooling furnace to cool down!

    Soon the glass in the cooling furnace was cooled and pushed out of the cooling furnace. Wang Bin and the workers immediately came forward and looked carefully. The pieces of glass were intact and crystal clear. Even if they didn''t look carefully, they couldn''t see the existence of special glass in the mold.

    Obviously, the glass produced this time is not the same as last time. Even in terms of quality, even the naked eye can see that it is better than yesterday, which makes Wang Bin relieved.

    However, he still picked up a piece of glass and entered his laboratory to test the furnace of glass.

    When the test was completed, Wang Bin''s heart was finally put down. The glass from this furnace was unexpectedly good, and even almost comparable to that produced by Wang Bin''s laboratory.
