The glass making process is a fairly simple process, yet it requires a knowledge of materials and heritage of experience that has endured and progressed out of countless trails and errors. This heritage did not happen over night, but rather, it was the result of many years of human development and the progression of the art of glass making. Without this kind of development, the reliable and strong glass that makes up our patio doors, vinyl windows, aluminum windows, and even car windows would not be nearly as dependable or enduring.
