Why glass bottles have wiring
Answer it from a professional point of view, that is the mold stitching line. Each glass bottle blown out of the machine has a stitching thread. Large stitches indicate that the molds are not properly mated; the molds have large stitches and the bottles and cans have large stitches. Logically speaking, the smaller the stitching, the better, but there will be no stitching. Unless the glassware is pressed, it has no stitches. The general bottles and bottles are blown by the machine, and they are all blown together with the two halves of the mold.
