It was all seat of the pants with lots of gas. The goal was trying to keep the upper 1/2 inch active. In any of these glasses, the DNA is right there in the glass but the thermal treatment is what kicks it. That includes the time at the gloryhole, blah blah blah. Glass composition is really important. I can't keep stressing that enough.
Where are we going and why am I in this basket?
