"And I always said to you as students, there are no secrets. In the first place, glass is transparent. If you understand how it's made, every piece has its history right there for you to read. All you have to do is be able to read it. So an Italian makes a piece. All the technique is there for us to see. It's a transparent material. And it's transparent to a trained mind. There are no secrets."
