  This short report is concerned with the well known and not yet satisfactorily
answered problem of the existence of two well distinct typical mass scales of
primordial halo objects: solar size objects (halo field stars) and globular
cluster size objects (10^5 solar masses and more). A likely possibility is that
almost all the gaseous content of the halo fragmented into massive clouds,
which, in their turn, recycled part of their gas to the environment in either a
quiescent either a violent way.
  The modes and quantity of mass loss depends on thermodynamic properties of
gas clouds, determined, in a zero-metal environment, mainly by hydrogenic
components evolution and influence on the equation of state.
  It is logical to expect that, due to the different dynamical and
thermodynamical conditions of the recycled gas, another typical fragmenting
mass scale is settled.
