No, just I was talking about the facility, not the carbon freezing process.
Same thing. Lando's exact words: "We
only use this facility for carbon freezing." So if you're talking about the facility, you
are talking about the carbon freezing process, because that's explicitly the only thing it does. He doesn't say "only for industrial carbon freezing" or "only for a crude form of carbon freezing" -- he says "only for carbon freezing." So Lando is saying that carbon freezing may kill Han, period. Anything beyond that is presuming data not actually present in the dialogue.
I thnk we may be getting off of the key point. Just to be clear, I'm not trying to interpret TESB in the context of the larger SW universe as it now exists; just the opposite, I'm trying to discern what the original intention of Kasdan, Brackett, Lucas, Kershner, etc. probably was when they made the film in 1980. So I'm limiting myself to the letter of the script and to the plot logic as presented in the film, and considering those entirely in isolation. Because my hypothesis is that the way carbon freezing was interpreted later is distinct from what it was originally intended to be.
Now, I doubt very much that Kasdan, Brackett, etc. gave much thought to the larger practice of medical cryogenics in the galaxy far, far away. They just wanted to manufacture a threat to Han Solo and Luke Skywalker. It had to be something that could trap a living person, but for the sake of suspense, it also had to be potentially lethal. So their goal was to create something that was dangerous, and they just slapped on some technobabble that gave the impression they wanted. It wasn't worked out in any more detail than that. So it's vague enough to leave a lot of questions, because this was just a well-made popcorn movie that nobody expected to be analyzed to death decades later. But the key thing is, they invented it to be dangerous, albeit potentially survivable. So any later work that portrays it as routine or reliable is diverging from that intention, however you rationalize it.
