  Dark Matter might be an accidentally stable baryon of a new confining gauge
interaction. We extend previous studies exploring the possibility that the DM
is made of dark quarks heavier than the dark confinement scale. The resulting
phenomenology contains new unusual elements: a two-stage DM cosmology
(freeze-out followed by dark condensation), a large DM annihilation cross
section through recombination of dark quarks (allowing to fit the positron
excess). Light dark glue-balls are relatively long lived and give extra
cosmological effects; DM itself can remain radioactive.
