It’s not that I can’t do it, but that I haven’t tried it. And I don’t know if it can be successful.

Even if it is made, it is still unknown whether the quality can be guaranteed.

At this moment, a man stood up: "Long live, the villain may be able to try it."

Zhu Cixuan was stunned: "Who is this person?"

Zhou Kui hurriedly introduced in surprise: "Long live, this person is called Zhang Fakui, and this tin water glass is from his hands."

Sure enough, there are many people who are hiding and lying on the verge of hiding dragons and tigers. Zhou Fakui briefly introduced his method of making round tube glass.

The glass plate is arranged on a forming mold having an outer peripheral surface with a circular cross-section, and then the glass plate is deformed by heating the glass plate by using the self-weight of the glass plate, so that the glass plate is transformed into a first deformation step in which the glass plate is formed into a shape along the upper side portion of the outer peripheral surface of the forming mold;

After the first deformation step, one side part of the glass plate is pressed to the forming mold side by the first pressing member located on one side of the forming mold, and the other side part of the glass plate is pressed to the forming mold side by the second pressing member located on the other side of the forming mold, thereby transforming the glass plate into a ring-shaped second deformation step;

And after the second deformation step, the bonding process of obtaining the glass tube is obtained by joining the two ends facing each other. In this way, it is possible to manufacture glass tubes with larger diameters and larger thicknesses.

To put it bluntly, this is the same as kneading. Glass will melt into liquid at high temperatures. As the liquid gradually cools down, it will become a soft body that can be kneaded at will. At this time, the glass can be shaped at will.

If this is the case, it can be made with the cooperation of many craftsmen, a large thickness and thick diameter glass tube, and the two ends of the glass tube must be thick and thin, which will be perfectly matched in the future. In this way, one section of water pipe can be made.

If you want to prevent water leakage, you can use fish glue. The ancient carpenters would use fish glue as adhesive. Moreover, this fish glue is pure and natural, pollution-free, and durable.

The glue used by these carpenters is magical. It is not only green and environmentally friendly, but also firmly sticky, but also will not damage the wooden structure of the furniture, so that the mortise and tenon structure can be disassembled and assembled at will without affecting the overall structure of the furniture. The more common ones are fish bladder glue, pig skin glue, etc.

Fish bladder glue has a history of nearly a thousand years in my country. According to the Compendium of Materia Medica, it has the effect of replenishing essence and blood, strengthening the kidneys and strengthening the foundation. Using fish bladder to make glue is a task that traditional Chinese medicine is still doing. The current traditional Chinese medicine prescription still has fish bladder glue, which is very expensive. It is also in the use of Chinese medicine fish bladder glue that people have begun to notice that it has a strong viscosity, especially rubber that boils over-boiled pharmaceutical glue. In this case, the use of fish bladder glue began to show.

Fish bladder glue is widely used. In addition to being used to bond musical instruments and make bows and arrows, it can also be used in classical furniture.

These are all the details. It seems that making glass tubes one by one does not seem difficult. The difficult thing is its transportation.

In an era when relied on animal power to transport, it is easy to imagine how difficult it is to build a tap water pipe from Yuquan Mountain to the Forbidden City.
