Have you played with glass balls? That is, marbles, the kind with patterns inside.
Every Chinese New Year, Kuangwan always packs out some toys that he once loved, and the colorful marbles are one of them. In my memory, when I was young, I was addicted to “Bouncer” as much as I am playing “Glory of the King” now. I can draw a circle on the ground to fight with my friends for an afternoon.
But while playing, have you thought about the same question as Kumamaru: how exactly are the patterns in the marbles put in ?
The Japanese popular science program THE MAKING has restored the manufacturing process for us. First of all, the material of glass marbles usually comes from waste glass bottles, which are sorted according to color, and then crushed into fine pieces for use as materials:
In this process, the assembly line machine will remove paper labels and other items on the glass, including the use of magnets to remove various metal material residues:
After processing and filtering, the waste glass becomes pure colored glass residues, which will be used as raw materials to be transported to the glass marble production line.
The first step in turning these materials into marbles is softening . The marble raw material, that is, glass slag, will be discharged into the dissolving furnace after entering the assembly line. The temperature here is as high as 1200-1400 degrees Celsius, which can soften the material just right, making it flowable and cut.
Speaking of the structure of the melting furnace is very similar to the combination of water dispenser + septic tank, after being softened by high temperature, the unnecessary raw material residues will float up or sink, and the real usable materials will flow into the outlet from the middle section and outwards. emission.
Then the material needs to be cut . The discharged glass material needs mechanical help to cut it into a suitable and uniform size:
Each one will be cut very evenly, and the cutting process looks very comfortable…even a bit greedy:
The cut marble material needs to be shaped and cooled . The molding is well understood. The cut marble material is not spherical and needs further processing. The common machine is the following:
This is a conveyor consisting of two continuously rotating trough drums. The marbles will continue to rotate and polish between the two grooved barrels, and at the same time the machine will transport them to the next assembly line:
Of course, the marbles are being cooled during the entire polishing and transportation process:
After the marbles are formed, the “racing time” is up. Marbles will race fast on various corners and further reduce their body temperature:
Finally reached the end of the track and flew into the cargo box collectively, and the transparent marbles were made.
So how does the pattern in the marble come out ? This kind of marbles is also called cat’s eye marbles. They are often regarded as treasures by friends because of their rare design and appearance, but the production process is actually not as complicated as we think.
To make this kind of marbles, you have to prepare from the first step of making marbles. In fact, the pattern inside is also made of glass, but it is colored glass.
The secret of the production is that the two different colors of glass are placed in different positions when they are softened. Generally speaking, the material of colored marbles in the furnace needs to be placed in the middle of the transparent marbles , which is the so-called “sandwich”:
When the two materials flow out, they are poured out together. At this time, the transparent glass material will just wrap the colored material. You can clearly see their layering when cropping:
The two materials will enter the forming and cooling stage together. At this time, the marble will continue to rotate under the influence of the machine, and the colored materials inside will be constantly shaken at the same time, and gradually turn into our common cat-eye shape before cooling. In this way, the color in the marbles is added.
Finally, no matter what kind of marbles, they must be inspected and packaged before being delivered to us.
Of course, it is difficult to control the pattern of marbles from this kind of assembly line. If you want marbles to have a more beautiful pattern, you need to make them by hand .
Simply put, the production of handmade glass marbles can be understood as a process of continuous softening and continuous shaping . For example, in the demo of the little brother below, first the transparent glass material is softened at high temperature, and then it is plated into a cylindrical shape:
Then cut out some desired colored glass cores, such as pure white, and then roll them at even intervals like a dipping sauce to make the glass core stick to the glass body:
Then soften again, so that the white glass core and the transparent material become one body:
Through continuous rotation and stretching, the white glass core is pulled out of the net pattern:
Then soften again and glue a layer of glass core:
Then continue to soften, and then process the shape of the glass core to make it flat:
After softening them again, add another layer of colored glass core, and repeat the previous steps, continue to plate it:
At this time, the marble material already has multiple layers of patterns, and the quilt is thin and long, especially at the front end, where the prototype of the marble has been plated:
Then break the connection point between the marble and the material to obtain the marble, but there are still cracks on the marble at the moment:
Use high temperature to soften it directly, so that the fracture marks disappear:
Finally, place it to cool, and a multi-layered marble is ready:
Of course, when making marbles by hand, different patterns have different production steps and processes. The following method is more like making a hamburger, first burn the core, and then sandwich the transparent glass material on both sides:
Finally stretched infinitely, softened, cut, and rolled onto a layer of glass core:
Then start to polish it, and plate it:
Finally, it is formed and cooled, and the internal pattern is also exquisite:
In addition, some superb touches can also be carved directly in marbles. For example, this Vicki Schneider, he continued to soften the marbles, and then continue to integrate other materials with the marbles:
The final result almost turned this glass ball into a transparent elf ball:
Another big boss, William Grout, created an underwater world inside the marble:
After reading the craftsmanship of the big guys above, I believe you have discovered that in addition to our common transparent and cat eyes, there are many types of marbles. For example, as we mentioned earlier, handmade works belong to Latticino core, which is characterized by a spiral net-like pattern structure in marbles:
The following types are called Indian Swirls, or Indian Swirls, but this type of marbles has nothing to do with India:

In addition, in terms of artistic sense, the Winlock Marbles series is also very famous. These marbles are as if infused with watercolor, the colors are gorgeous and eye-catching.
Fritts art glass is also one of the highly acclaimed marble series. Their patterns are more delicate and the lines are more distorted, giving me a feeling of butterfly wings:
Of course, cosmic marbles have become more popular in recent years. How does it feel to hold the universe in your hand? Just look at Satoshi Tomizu’s work:
He used other materials such as opal to create various planets in marbles. The gold and silver particles embellish the dazzling galaxy. When the lights are turned on, the effect should not be too beautiful:
When it comes to cosmic marbles, one has to mention Gateson Recko. The starry sky he created is even more profound and mysterious:
This is a dynamic effect, and the sea of stars is hidden in the small marbles:
In addition, Kuang Maru also found another fairy work on the official website of Gateson Recko, an island hidden in the marble below:
How is it, do you really want to have one after reading it? Of course, the price of these marbles is also very “fairy” . Take Gateson Recko’s series of works, the price is between 400 and 1,200 US dollars, which is the most expensive around 8,000 yuan.
Feeling a bit outrageous? But for rare marbles, these numbers are nothing at all . For example, the classic lutzes marble below. It was created by the well-known marble company Christensen Agate. It is understood that because its color is extremely rare and has a certain age value, it was auctioned for $25,000 and is one of the most expensive marbles in the world.
Yes, a small ball is worth more than 160,000 RMB. So, if you have marbles in your hand, don’t forget to tell each other, don’t abandon them easily, after all, maybe one of them is a peerless orphan, and you can rely on it to make a fortune.
