The soldering process fixes the glass and the glass together. Because it is made by hand, it has the randomness of handwork. The uneven black lines are the marks left by the craftsmen by hand, which is the unique style of Tiffany. All the colors of the glass are fired instead of post-processing and coloring, and the unique modern craftsmanship design is perfectly integrated with the classic elegance, so that the whole lighting has a modern sense of fashion and antique.
