From the moment the gob is cut and delivered, every mechanism in its path either preservers its integrity or introduces a variable the process can’t recover from.
Each point of the glassmaking process is a point where quality is either kept or quietly lost.
Glass doesn’t fail at the end of the line. It fails in the forming stage, in the mold, in the compound that was almost right.

Every contact point in the forming process has its own chemistry, and every chemistry has its own margin of error.
The difference between a perfect container and waste is often invisible.
It all begins with understanding
