Technicians carefully select high-quality glass, heat the glass at a high temperature of 1300℃ to melt it into a liquid state, and then shape it into various forms according to design requirements—such as swan necks, lilies, or flames. After annealing treatment for 5 to over 30 hours, the exquisite shapes are finally formed. The entire operation process is strictly controlled to ensure the aesthetics of the glass after forming.
