Plas'ss is an optically transparent organo-metallic compound initially discovered on Telios Prime. It is essentially created by realigning the molecular structure of Illan-ta to make it "permeable" to certain energy wavelengths, at the expense of reducing the material's inate structural properties. It has been discovered that the exposure of this material to the vacuum of space further changes the external structure of the material and in essence annealing the surface, leaving a extremely strong, optically transparent material which is used in numerous applications.
