“In the glass pieces, what fascinates me has a lot to do with the essence of something that has one appearance but is really something completely different. For example, glass is a (super-cooled) liquid, not a solid. It’s a pretty amazing thing that a material as ubiquitous as glass can masquerade like that. It’s like having a mask but the mask is identical to the real thing.”
