Glass blowing requires skilled craftsmen who possess both the mastery of vacuum glass lamp blowing and a high level of artistic literacy in order to complete the task. Craftsmen use special materials such as glass tubes, glass rods, and colored sandblasted glass to melt and blow various glass crafts in flames that can reach up to 800 degrees Celsius. The innovative glass vacuum blowing process solves the problem of assembling light sources inside glass crafts and has become unique colored lamps domestically.
