Two varieties of black andesite porphyry. Incorrect name: breccia, ancient name unknown.
Used from Predynastic to Early Dynastic Periods. As an example two jars from Egypt. I would love to have the one with yellow :-)

The last one, 10th color / variety of porphyry - trachyandesite porphyry, black matrix with pale gray.
Roman name - possibly knekites, Italian name - porfido serpentino nero (do not confuse with serpentinite!).
