The secret sauce of all of this is the precise controlling of the timing and temperature of the draw; that’s what gets the pristine transparency and low signal loss that communicators want. “If you do something very abrupt with glass, the material is not homogeneous anymore,”
Mazzali said, because the chemicals will clump up and you’ll lose the architecture that has been carefully engineered into the glass. Any variations in density—however minor—will cause the light to scatter. And scatter means loss.
Mazzali led me into the wide white hall outside the prototype demo room to take the elevator to a higher floor of the R&D lab. As we went up, he told me what was about to happen. “We’re going to need safety glasses.” We came out of the elevator, put on the glasses, and looked up at a big steel box with one side missing. “What comes after the blank?” Mazzali quizzed me.

I tried hard to remember what he had told me minutes before: “You’ve got the big thick thing, and then you take out all the moisture and all the impurities and slenderize it,” I gamely responded. Mazzali pointed out a clear post-processing glass tube, with the core visible. “After you have that piece of glass, what’s the next step?” He was enjoying being the teacher. “You draw, the globule comes first, and then the very skinny stuff comes next,” I said, gabbling a bit.
