The raw materials of the glass balls are various natural ore powders or glass fragments. According to the glass composition, they are made into batch materials and sent to the glass melting furnace for melting. In order to increase the color of the glass balls, a small amount of soda ash and clarifiers are added to the raw materials. Will produce colorful glass balls.
The raw materials are heated to 1400 degrees in the melting furnace to form molten glass. The molten glass flows out from the material port to form a flowing liquid. The flowing liquid is sheared into spheres 200 times per minute.
The billet passes through the rolling groove and falls into the ball groove formed by two rollers with the same rotation direction. The billet rotates on the roller and its own surface tension acts to gradually form a smooth and round glass ball. The size of the glass ball is determined by the thickness of the fluid, the flow rate and the speed of the scissors.
There are also some glass balls with various patterns. Let’s see how they are made. In fact, the patterns inside are colored glass. The colored glass is melted and poured into the transparent glass to form a sandwich glass fluid. The patterns inside are all It is produced randomly and will not be exactly the same.
