A low energy effective field theory model for QCD with a scalar color octetfield is discussed. The model relates the gluon mass, the constituent quarkmasses and the quark condensate. The gluon mass comes about $\sqrt{N_c}\,\Lambda_{QCD}$ with the quark condensate being proportional to the gluon masssquared. The model suggests that the restoration of chiral symmetry and thedeconfinement transition occur at the same temperature and that, near thetransition, the critical exponent for the condensate is twice the gluon massone. The model also favors the decoupling like solution for the gluonpropagator.
