A long time ago, when the industry was not very prosperous, crystal double-layer glasses were hand-made by the craftsman, so at that time there were still relatively few crystal double-layer glasses. The current crystal double-layer glass cups are all made by machinery, and their applications are widespread. Two methods of making them are as follows. The editor has compiled two commonly used methods for you to explain in detail.
1. Hand-made crystal double-layer glass: Hand-made technicians basically need years of training before they can independently operate the production process. Among them, when the potassium glass melts to a viscous state, individual bubbles sometimes remain. The manual technician picks up a crystal ball containing 1 bubble through one end of the long steel tube, rotates, blows and shapes, and then goes through a series of pure hand-made procedures such as cutting, polishing, etc., only a crystal clear crystal wine glass can be formed. Moreover, not every hard work can be successful, so now the output of handmade crystal double-layer glass is small and the cost is high.
2. Machine-made crystal double-layer glass: In machine-made production, the potash glass is melted to a very dilute state, so that the bubbles inside are easy to get out, just like in water, and then the potash glass is poured into the mold like water. , Forming and cooling, and then after mechanical polishing, it can be formed.
Note: Because of artificial reasons, the unique shape of the handmade crystal double-layer glass can better reflect the exquisite skills, so it is suitable for high-level consumption, and a good handmade crystal double-layer glass has a certain investment value. The mechanically made crystal double-layer glass It is an assembly line, each product can be produced in large quantities, and the cost is low, which is suitable for daily consumption.
