Processing steps

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