In the past, the internet was underdeveloped, and children could only have fun with toys. Many toys accompany children throughout their childhood, and glass marbles are one of them. And both men and women like glass beads, because they are not only fun, but also very beautiful, and colorful beads shine in the sun. There are many styles of glass marbles, the most common one is transparent glass beads with patterns in the middle, so how is this pattern made?

To understand how patterns are made, we must first understand how marbles are made. However, the raw material is waste glass. After the waste glass is collected, it is completely heated at high temperature to melt it. Then the template condenses the glass again. Before the glass liquid is completely solid, all the glass is cut into a certain shape, but it is not spherical. After that, these identical glass bodies were reprocessed and polished and became spherical, which is how the glass balls were formed.

When we were young, we had many fun games, such as throwing sandbags, jumping rubber bands, playing marbles and so on. Do you know how to get beautiful patterns on glass marbles? Some factories make glass beads from discarded glass bottles. Workers throw these broken glass bottles into a high-temperature melting furnace to melt, and then pour liquid transparent glass into an operating furnace. Liquid colored glass is poured into the tube in the center of the furnace, and then polished, and a glass ball with colored patterns is born.

The pattern of each glass marble is random, but the color of this glass ball is random, so some people will make it by hand in order to customize it. They first prepared quartz sand and other raw materials and poured them into a boiler to make molten glass. Then use an iron bar to rotate back and forth in it, and the molten glass will stick to the iron bar for molding, and put the desired color bar into the mold in advance. Then put all the molten glass into the mold while it is hot, and the color bar will stick to the molten glass.

At this time, all of them are put back into the boiler for heating, and the colored strips are integrated with the glass liquid. Before the molten glass cools, the workers put it on the steel plate, roll it back and forth to form a cylinder, and then take out special scissors. Cut the ball while rotating, then polish the marble mold and fire it with flame, and a round marble will be ready!
