Ever wondered how the tiny quartz crystals in your watch, computer, TV, remote control, microwave, car key, etc are made? New Zealand manufacturer Rakon has a a very nice presentation of the entire process here, in either slideshow or single-page format. (The pictures are better in the slideshow)Very cool!  The first picture is of a multi-blade slurry saw, and the second is of the x-ray machine used to check crystal orientation… I knew that diffraction would show up here somewhere.
