Compressed Hedbergite II-Grade

When asteroids containing hedbergite pass close to suns or other sources of intense heat can cause the hedbergite to glassify. The result is called II-Grade or vitric hedbergite and has 5% better yield than normal hedbergite. Hedbergite is sought after for its high concentration of Pyerite and Nocxium. This material is compressed and a much more compact form of the original material.
