Carbon-freezing Chamber
a specialized chamber which preserves Tibanna gas for transport by freexing it inside carbonite. Lando Calrissian had one on his Cloud City mining colony. The Tibanna gas is first pumped into the chamber, and then mixed with molten carbonite. This mixture is then frozen, which traps the gas inside the block of carbonite until it is released in a reversal process. The process has often been used on living beings, as a form of torture or retribution. Darth Vader was going to use Calrissian's chamber to freeze Luke Skywalker for transport to the Emperor on Coruscant, and had Han Solo test-frozen first. If properly frozen, a living being goes into a state of hybernation until the carbonite is melted.
