The lost wax method is more suitable for casting small pieces and objects with many hollow patterns.
The second step is metal mold casting, where metal is made into a mold and bronze liquid is poured into the mold.
It can be used for multiple purposes, such as making weapons, but it cannot cast a bell.
Then there is the clay mold method. Yellow clay is used to make molds, which have good fixability and high temperature resistance, and are most suitable for bell casting.
The bell cast in this way not only has a beautiful appearance, but also, most importantly, has good sound quality.
When making clay molds, the yellow mud must have a temperature resistance of 1560°C, the soil must be highly viscous, resist shrinkage, cannot collapse the mold and collapse the mold, and the reducibility must be better.
Jingyun Bell is made of copper and tin alloy, using the "multiple mold casting method", that is, the mold is divided into 5 sections, a total of 26 molds, and cast in one go.
Therefore, if he imitates Jingyun Bell now, he will face two challenges.
One is the selection of bronze materials, and the other is the production of clay models.
After reading the inheritance of Jingyun Bell, Chen Wenzhe naturally has an idea of how to choose copper materials and how to make copper-tin alloy.
As for making clay models, isn't it just playing with clay? In this regard, Chen Wenzhe is professional.
The most important thing in making a clay model is actually the various patterns on the copper bell, as well as the stalactites used for tuning.
In fact, not only the 32 stalactites are tuners, but also other places, as long as the patterns are there, have some effect.
This is why Chen Wenzhe originally wanted to learn the music of the Tang Dynasty.
It's a pity that he didn't take time out to take a look at the collection of the big collector in Dahai City.
In other words, he was never available and did not summon him.
After joining the Collectors Association, Chen Wenzhe’s personal antiques were exhibited, but they haven’t been organized yet!
Chen Wenzhe asked Professor Tao that generally such exhibitions are held in a month near the end of the year.
In this way, the Gregorian New Year has passed and the lunar New Year's Eve has not yet come. It is in this space that the big guys have time to see the exhibition.
In fact, now that I think about it, it is superfluous to find another Tang Qin and study the music specifically.
Because Chen Wenzhe had seen too many tuning processes on this Jingyun Bell.
In other words, he already understood the music of the Tang Dynasty, at least the tuning methods of the percussion music of the Tang Dynasty.
Therefore, besides the copper material being the most important, the second step is the making of the clay model.
Because it is a multi-clay mold casting, that is to say, Chen Wenzhe will make five sections, a total of 26 clay molds, and cast them in one final step.
The most important thing is, who can guarantee that when cast in this way and welded together, it will form a big bell with a beautiful and rich sound?
This ancient musical instrument is truly amazing.
Many people say that being able to make a famous clock is due to luck, but this is not necessarily true.
For example, the Jingyun Bell is a large bell ordered by the emperor to be made. Can you rely on luck to make it?
For some people who do not understand the situation and do not understand the technology, they believe that the success of the casting of famous clocks depends to a large extent on luck.
It is not easy to cast a bell, because no caster can guarantee that the bell he casts will be a flawless and beautiful bell that is handed down from generation to generation.
But, do you really have to try your luck?
If making big bells is a matter of luck, what about chimes, which are numerous ancient percussion instruments?
Does the casting of this kind of thing also require luck?
If you can successfully cast four, six, or even sixteen or thirty-two pieces at one time, your luck will be too good.
Therefore, tuning, making clay models, and later carving, polishing, and connection are all very important techniques.
In other words, making a big clock in ancient times not only cost money, but also took a lot of energy.
Otherwise, if you can't think of anything and can't do anything, you won't succeed.
This requires extremely advanced knowledge of music theory, which obviously cannot be accomplished by luck.
Therefore, even if there is an emperor to promote it, casting a qualified and famous clock will still cost a lot of money.
If it costs so much, why cast it?
One is that the emperor thought, and the other is that it is really necessary to cast such a big bell.
Isn’t it the pursuit of beautiful things when human beings live?
The sound of bells is also a pursuit.
To give a random example, Hanshan Temple will ring 108 bells on New Year's Eve. Entering Hanshan Temple to listen to the bells is not free, but requires a 320 yuan ticket.
On average, each time you listen to the bells, you spend about 3 yuan. This may be the most expensive piece of music in the world.
But even so, why do pilgrims still flock to Hanshan Temple’s bells on New Year’s Eve?
The reason is very simple, because the sound made by the ancient bell of Hanshan Temple is extraordinary.
Sima Qian wrote in "Historical Records. Music Book": Beautiful music can "turbulence the blood, connect the body and mind, and rectify the heart."
Modern medicine has also proven that the sound of ancient bells can really "drive away evil spirits and cure diseases."
Facts have proved that residents living in Fengqiao Town, 10 kilometers around Hanshan Temple, which is within the reach of the bell, rarely suffer from psychological, digestive system and other diseases, and there are many old people in the town.
Chen Wenzhe has been assigned the task for a long time, and he also knows something about the world's famous clocks.
If he doesn't know much about it and has tried his best to confirm it, he really doesn't know that ultrasound can cure diseases.
For example, the grand bells can not only stimulate the righteousness in the human body, but when the ancient bells ring, they will also produce powerful ultrasonic waves. This ultrasonic waves can kill rabies virus, encephalitis virus, whooping cough and diphtheria bacteria.
Hard to survive.
This kind of thing would be nothing more than a legend.
Chen Wenzhe has actually verified that although ultrasound cannot treat rabies, the rabies virus can be inactivated by sunlight, ultraviolet light, ultrasound, 2% soapy water, iodine, etc.
Chen Wenzhe really couldn't believe such a thing unless it was discovered, but it was a fact.
There is a reporter who does not believe that bells can cleanse people's soul. He once sat on the steps of Hanshan Temple and listened to 108 bells.
He said: After listening to the New Year's bell, my heart is filled with positive energy like sunshine. I believe that I will be able to work more diligently tomorrow morning and strive to achieve better work results in the coming year!
Whether you can believe this statement, you will know for yourself by listening to the bells of Hanshan Temple.
Now is the Internet age. Even if you don’t travel, you can still listen to recordings.
Chen Wenzhe has heard it, and he has also heard the sound of singing bowls made using a large number of modern high-tech technologies.
Chen Wenzhe did not dare to say whether the sound of this kind of singing bowl could cure diseases, but after listening to it, he did feel that it sounded very good and even relaxing.
At the very least, I like to listen to it. Sometimes I can't help but listen to it over and over again. It can be said that the lingering sound is lingering and very pleasant.
The sound of bells is the same, but it cannot sound endless like a singing bowl.
However, if this thing is copied now, it will definitely have high economic value.
