Abstract
As the chirally restored phase ends with T coming down to T_c, a phase resembling a mixed phase is realized, during which the hadrons (which are massless at T_c in the chiral limit) get their masses back out of their kinetic energy. The gluon condensation energy is fed into the system to keep the temperature (nearly) constant. Lattice results for the gluon condensation are matched by a Nambu-Jona-Lasinio calculation. The latter shows that below T_c the chiral symmetry is barely broken, so that with an about 6% drop in the scalar coupling G it is restored at T_c. Nearly half of the glue, which we call epoxy, is not melted at T_c.
