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 synthetic type IIa diamond windowss with a mechanical press fragments crushed down to a thickness of about 10 microns
