Beyo

Beyo is a variation of obsidian mixed with different hardened minerals. At a cold enough temperatures, it will melt to become a coolant of sorts. This coolant frequently cools down, trying to restore the solid-state, as the coolant itself is an anomaly.

Crystal (Solid) Beyo
The inner cores of Crystal Beyo's atoms are all superheated, but it is so small that feeling the rock only produces a room temperature degree. A chemical reaction can be caused by rapidly decreasing the temperature around the Beyo, which would reduce the pressure on it and cause the atomic structure to melt it from the inside-out. At this point, it would become Liquid Beyo.

Liquid Beyo
The coolant, when in the stage, is known as Liquid Beyo. Liquid Beyo is, unlike Crystal Beyo, looks like a clear shampooing substance. It can form either into a deadly vapor or back into a solid depending on what temperature it is at. If the temperature around it is hot, the liquid will become a solid again. If it is subzero, it will become a vapor.

Vaporous Beyo
At this stage, the Beyo becomes a noxious gas. Upon touching the skin, it will freeze and crack it. If breathed in, it will freeze over the lungs and harden the edges of the throat with Crystal Beyo. Vaporous Beyo also gives off fumes and small pockets of hyper-stressed radiation, which can damage such species as the Gand, Quarrens, or Ithorians.

GT-37s
The GT-37s are a type of cryogenetic chamber that use Liquid Beyo as a source for freezing. In reality, the edges of the glass become superheated, causing the liquid to freeze over back into a Crystal Beyo state. During this frozen state of Crystal Beyo, the temperature is raised enough to become a solid, but not enough to revert back to its pitch-black coloring. Therefore, the person inside the cryogenetic tube appears to be cased under layers and layers of glass.
