Strangeness and charm degrees of freedom are considered on the partonic level. First we present a model of the fully equilibrated quark-gluon plasma with thermal parton masses and find a considerable contribution of strangeness and also some charm. Then the kinetics of chemical equilibration processses of in an early hot glue system is modelled, i.e., the cooking of light and strange quarks in an expanding gluon gas is followed. The degree of equilibration depends on uncertainly known rates, however, we find that such penetrating probes as hard photons are less sensitive to details of the equilibration. Finally, we estimate the very early charm production in not yet thermalized parton matter and find indications for a clear dominance of the glue fusion processes, i.e., charm probes likely the early glue distribution. {copyright} 1995 {ital American} {ital Institute} {ital of} {ital Physics}.
