The epoch of the first second itself has not been tested directly yet; however, it is constrained by experiments at particle and heavy ion accelerators. Here I attempt to describe the epoch between the electroweak transition and the primordial nucleosynthesis.\n  The most dramatic event in that era is the quark--hadron transition at 10 $\\mu$s.
