Step Chronology Date Type Process Changes
#1 before layer formation 2011-07-19 mechanical Manual selection under optical binocular of about 10 matrix grains of about 30-50 microns diameter. Matrix selected based on its black color and on its fine-grained texture
#2 during layer formation 2011-07-19 mechanical Grains pressed between two diamond windows with a mechanical press grain crushed down to a thickness of about 10 microns
