 Welcome back, ladies and gentlemen. I now continue my Socrates in the City conversation with Stephen Collins. Now, so I had, so logically I'm thinking, now wait a minute, if this thing is not on the surface, it's not in the melt glass, it's below the melt glass, it's a boiled zircon crystal at 5,000 degrees, an eighth of an inch at least from the surface of this thing. I said, well, if it's that hot inside, how hot is it at the surface?
