It's in the section near the end where Henry reprinted some of his funniest "Ask Dr. Glass" letters. Apparently, someone wrote to Henry asking if it would be feasible to fire a round into a gather of hot glass. They wanted to know if the glass would actually shatter from the impact, or if it would lodge itself in the gob like it was "embedded in amber", or somesuch.
I haven't unpacked my copy since moving my studio, so I don't know exactly what they said, but it went into all manner of pseudo-scientific descriptions of what might happen.
