Canary yellow when fresh
Lustre:
Vitreous
Hardness:
2 - 3
Specific Gravity:
6.87 (Calculated)
Crystal System:

Name:
For Dr. Kenneth Junghwa Hsu [June 29, 1929 Nanjing, China - ], Professor Emeritus, Swiss Federal Institute of Technology, Zurich, Switzerland. Dr. Hsu has had an illustrious career in geology and has been awarded the Wollaston Medal, Penrose medal, Twenhofel Medal, American Association of Petroleum Geologists President's Special Medal, and the Bownocker Medal from his alma mater (Ohio State University) and is a member of the National Academy of Science [USA]. His early career was working as a petroleum geologist, before he entered his academic career. He is also an inventor and holds patents for the integrated hydrologic circuit and the hydrotransitor and 14 other inventions. Dr. Hsu created a major new innovation of residual oil recovery involving water injection into oil reservoirs (colloquially called fracking).
