Natural Science Forum / Earth Science / Mineralogy / June 2004Chinese green quartz treatment?
Hi, Does anybody know how the recent "find" of Chinese green "chromium" quartz is treated? Thanks! Alan  SignatureAlan Guisewite Senior Research Technician / RI Webmaster adg@cmu.edu Carnegie Mellon University Robotics Institute Official: http://www.ri.cmu.edu/people/guisewite_alan.html Mineral Collection: http://www.cs.cmu.edu/~adg/adg-piimages.html Celebrate with us! http://www.ri25.org Dear Alan, Could you be more specific? I find several links with www.google.com--->"Chinese chromium quartz", etc (including some of your owns dating back to several years! ...). Ni and Cr salts seem to have been widely used again and again, and other answers are plentyful.
