Hexorium was first discovered back on 13th of June 2012. Back then, not much was known about it and it was named "Xychorium". The adventurers used it for a lot of different purposes, but they were mostly decorative in nature, as not much was known about the material back then.
Recently, on 14th of April 2015, a company called CelesTek Technologies emerged with a cause to find a proper use for the mineral. They conducted plenty of research in both properties of the material and potential uses. Due to the crystalline structure, the name of the mineral was changed to "Hexorium", to better reflect the hexagonal nature of the crystals. The results of the researches were interesting, showing that the material is not limited to the five base colors, and that these colors can actually be mixed under right conditions. In addition, the tests have shown a way how to use the material to transfer energy over long distances and use it inside electronic devices.
As a result, the company created a large number of machines and vowed to continue with their research and bring even more things to the general public. Once enough research has been done, the company decided to debut their discoveries and technology on 24th of May 2015.
The most prominent feature of Hexorium is that it glows in the dark. Upon further observation, it can be noticed that the crystals don't actually reflect outside light, as the ambient lighting does not affect them. This is most easily visible with White Hexorium Ore, as the crystals' brightness is identical during both day and night making them appear gray during day. In addition, light emitted by the crystals doesn't seem to affect any other materials either, so they cannot be used as a light source.
The molecular structure of Hexorium appears to be hexagonal. This is evident when looking at Hexorium Monoliths.
Red Hexorium Crystals
The Red Hexorium Crystals appear to be similar in structure to Green Hexorium Crystals, but their structure appears to be offset by -120°. It is not exactly understood why or how this happens yet. The result is a different hue. These crystals don't seem to have high electrical conductivity, so they are generally not used for electronics.
Green Hexorium Crystals
The Green Hexorium Crystals appear to be the base color of all crystals, as their structure doesn't have any offset. These crystals don't seem to have high electrical conductivity, so they are generally not used for electronics.
Blue Hexorium Crystals
The Blue Hexorium Crystals appear to be similar in structure to Green Hexorium Crystals, but their structure appears to be offset by +120°. It is not exactly understood why or how this happens yet. The result is a different hue. These crystals don't seem to have high electrical conductivity, so they are generally not used for electronics.
White Hexorium Crystals
The White Hexorium Crystals appear to be composed of all three (Red, Green, and Blue) crystals and as such, they emit pure white light. The White crystals appear to be found way deeper underground. Studies have shown that this is the result of the Discoloration process. The process is not well understood, but appears to be related to high pressure and lack of light. Compared to the other crystals, White have better conductivity, so they can be used for electronics.
Black Hexorium Crystals
The Black Hexorium Crystals are the most interesting of all. They appear to be similar to White Hexorium Crystals, but they have a way higher density. This makes them lower the light output by a huge amount. Black crystals are in fact still white, but the light output is reduced by such a significant amount that it was decided to call them Black. Due to the higher density, they appear to have the property of manipulating Energized Hexorium. In addition, they have a way higher conductivity than White crystals, so they are the main component for all electronics.
Energized Hexorium is a special state of Hexorium. It was discovered that, when combined with Redstone, the Hexorium molecular structure changes dramatically. In fact it is no longer a solid and begins to intensely glow.
The process seems to be a chain reaction. By adding a single piece of Redstone to a Hexorium crystal, every crystal touching it will become Energized. It is not understood what happens with the Redstone used, but it seems to disappear. During the process, all of the different crystals used will blend their matrices together, forming all of the different colors. The special situation where Red, Green, Blue and White are combined seems to create a special "rainbow" color. This form of Energized Hexorium seems to constantly shift the color, going through the full spectrum.
Energized Hexorium has properties vastly different from the natural form. It seems to emit a much larger amount of light, and its structure is no longer solid. The structure becomes a solid-fluid, conveniently changing to solid where needed. This structure seems to be extremely brittle and breaking it with anything other than Hexorium Manipulator will result in all Hexorium crystals discharging, returning to their original state. Luckily, Energized Hexorium has a lot of uses, and is one of the most widely used materials when dealing with Hexorium.
The material appears to have great conductivity, and as such is used with Hexorium Cables to transfer HEX energy between machines. It is used in all different Hexorium machines as a base block. Its matrix can also be artificially reconstructed into a fine Energized Hexorium Monolith. These monoliths keep the energized properties and can be used with Energy Pylons to conduct energy remotely. And finally, people love to use it for decorative purposes.
