Sylvite ores carved out of moons can occasionally yield very high densities of the valuable minerals. When this happens the ore is called Glistening Sylvite and reprocessing such ores will yield twice the normal volume of useful material.
A ubiquitous ore commercially mined from moons, Sylvite is very useful as it yields good quantities of Evaporite Deposits used as basic elements of some advanced materials. Sylvite ores will also yield Mexallon and Pyerite.
This material is compressed and a much more compact form of the original material.
